Run the quit command to exit from the AAA view. l Configure non-authentication. 1. Run the system-view command to enter the system view. 2. Run the user-interface [ ui-type ] first-ui-number [ last-ui-number ] command to enter the user interface view. 3. Run the authentication-mode none command to configure non-authentication. Step 3 Run the user privilege level level command in the user interface view to control the user rights. ----End Commissioning Results After the preceding configurations are complete, perform the following operations to check whether the configurations are correct. 1. Run the Telnet client program on the PC, and enter the IP address of the interface to which you want to connect to. 2. Enter the user name and password in the login window. If the user is authenticated, a command line prompt such as <HUAWEI> is displayed. It indicates that you have entered the user view. Troubleshooting If the Telnet login fails, perform the following operations: 1. Check that network connections are proper. Run the ping command on the client to check network connections. If ping results are negative, network connections are faulty and Telnet connections cannot be set up. Check if unstable connections that cause packet loss or occasional login failures exist in the network. If network connections are faulty, follow the procedure described in "The Ping Operation Fails" in the HUAWEI NetEngine80E/40E Router Troubleshooting to locate and rectify the fault and ensure that the Telnet client can successfully ping the Telnet server. 2. Check whether login users on the NE80E/40E have reached the maximum. Log in to the NE80E/40E by using the console interface. Then, run the display users command to check whether the VTY user interfaces are all used. By default, a maximum of five VTY user interfaces are available to login users. You can run the display userinterface maximum-vty command to view the allowed maximum number of login users.

This means that to allow a client to telnet to the NE80E/40E, you must specify the IP address of the client in the permit rule of the ACL bound to VTY user interfaces. 4. Check that the access protocol has been correctly configured in the VTY user interface view. [HUAWEI] user-interface vty 0 4 [HUAWEI-ui-vty0-4] display this user-interface vty 0 4 authentication-mode aaa user privilege level 3 idle-timeout 0 0 protocol inbound ssh The protocol inbound { all | ssh | telnet } command is used to specify protocols supported by the current user interface. telnet is the default parameter. If ssh is specified, Telnet login is prohibited. If all is specified, both Telnet login and SSH login are allowed. 5. Check whether extended VTY user interfaces 16 to 20 are available to login users. These user interfaces are reserved for NMS users. Whether VTY user interfaces 0 to 14 are all used, VTY user interfaces 16 to 20 are open to NMS users (whose user type is netmanager) only, not common login users. The display users command can be used to check the user login information of every VTY user interface. 6. Check that a password has been set in the user interface view. If the authentication-mode password command has been run in the VTY user interface view to set the authentication mode to password, the set authentication password command must be run to set an authentication password. The authentication mode can also be set to aaa by running the authentication-mode aaa command or to none by running the authentication-mode none command. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 9 HUAWEI NetEngine80E/40E Router Commissioning Guide 7. 2 Logging In to the NE80E/40E Check that the user level is correct. If the authentication mode in the VTY user interface view is set to password or none, you need to check the user level. Low-level users, after login, are not allowed to run high-level commands such as the system-view command. If you use an administrator account to log in to the NE80E/40E, you can run the user privilege level level command to configure the level of commands that the user logging in through the current user interface can use. NOTE By default, command levels are 0, 1, 2, and 3. Before the upgrade of command levels, user levels 3 to 15 are the same, which are all management levels. 8. Collect the following information and contact Huawei technical support personnel: l Results of the preceding operation procedure l Configuration files, log files, and alarm files of the NE80E/40E 2.3 Logging In to the NE80E/40E by Using SSH This section describes how to log in to the NE80E/40E by using SSH. SSH is a secure remote login protocol, which is developed based on the traditional Telnet protocol. Compared with Telnet, SSH is greatly improved in terms of the authentication mode and data transmission security. Prerequisite Figure 2-6 Networking diagram of logging in to the NE80E/40E by using SSH network SSH Client SSH Server Before logging in to the NE80E/40E by using SSH, complete the following tasks: l Ensure that the NE80E/40E is working properly. l Log in to the NE80E/40E by using the console interface and configure an IP address for each interface on the NE80E/40E. l Ensure that there is a direct or reachable route between the SSH client and the NE80E/ 40E. NOTE Perform the following configurations on the NE80E/40E that serves as the SSH server: Procedure Step 1 Configure the NE80E/40E to generate a local key pair. 1.

Step 2 Configure a VTY user interface to support SSH. 1. Run the system-view command to enter the system view. 2. Run the user-interface [ ui-type ] first-ui-number [ last-ui-number ] command to enter the user interface view. 3. Run the authentication-mode aaa command to specify AAA authentication as the authentication mode. 4. Run the protocol inbound ssh command to configure SSH as the access protocol in the VTY user interface view. NOTE AAA authentication must be configured in the VTY user interface view; otherwise, the protocol inbound ssh command does not take effect. Step 3 Run the ssh user user-name command in the system view to create an SSH user. Step 4 Run the ssh user username authentication-type { all | password | password-rsa | rsa } command in the system view to configure an authentication mode for SSH users. Perform one of the following operations as needed: l Configure password authentication. – Run the ssh user user-name authentication-type password command to configure password authentication. – Run the ssh authentication-type default password command to configure default password authentication. If local authentication or HWTACACS authentication is used, default password authentication will be preferable for SSH users when the user number is great, which can simplify configurations. l Configure RSA authentication. 1. Run the ssh user user-name authentication-type rsa command to configure RSA authentication. 2. Run the rsa peer-public-key key-name command to enter the public key view. 3. Run the public-key-code begin command to enter the public key edit view. 4. Enter hex-data to edit the public key. 5. Run the public-key-code end command to exit from the public key edit view. If illegal hexadecimal data is entered, no key will be generated after the peer-public-key end command is run. If key-name specified in Step b has been deleted in another window, the system will display a message indicating that the key does not exist and return to the system view directly after you run the peer-public-key end command. 6. Run the peer-public-key end command to return to the system view. 7. Run the ssh user user-name assign rsa-key key-name command to assign the SSH user a public key. Step 5 In password or RSA authentication mode, create a local user with the SSH user name in the AAA view. 1. Issue 02 (2011-09-10) Run the aaa command in the system view to enter the AAA view.

Procedure Step 1 Run the display temperature[ [ lpu | mpu | sfu ] slot slot-id [ pic pic-id ] ] command to view the temperature status on each board. <HUAWEI> display temperature SlotID2 Base-Board, Unit:C, Slot2 PCB I2C Addr Chl Status Minor Major Fatal Adj_speed Temp TMin Tmax (C) ----------------------------------------------------------------LPUF 1 1 0 NORMAL 70 80 90 60 70 36 LPUF 1 2 0 NORMAL 60 70 80 50 60 33 LPUF 1 4 0 NORMAL 70 80 90 60 70 35 LPUF 1 5 0 NORMAL 80 90 100 70 80 39 LPUF 1 6 0 NORMAL 70 80 90 60 70 38 LPUF 2 76 1 NORMAL 90 96 102 80 90 39 LPUF 2 76 2 NORMAL 90 96 102 80 90 40 TCMB 1 3 0 NORMAL 70 80 90 60 70 34 TCMB 1 7 0 NORMAL 60 70 80 50 60 31 Pay attention to the values of the fields displayed in boldface. The Temp(C) field indicates the current temperature. The Minor field indicates the threshold of a high temperature for a minor alarm. The Major field indicates the threshold of a high temperature for a major alarm. The Fatal field indicates the threshold of a high temperature for a critical alarm. If the board temperature reaches or exceeds the value of the Fatal field, the NE80E/40E may work abnormally or be damaged. If the displayed value of the Temp(C) field is lower than that of the Minor field, the board temperature is normal. Then, go on with the subsequent commissioning. ----End Troubleshooting If the board temperature exceeds the threshold, perform the following operations: 1. Check whether fans are faulty and replace any faulty fans. 2. Check whether the air filter is clogged. If it is clogged, clean it.

Step 3 Run the ping command to test Ethernet link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting l If the physical status of an Ethernet interface is Down after the interface is configured, perform the following operations: 1. Check that the peer device is started. If the peer device is not started, start it. 2. Run the display interface interface-type interface-number command to view optical module information and interface configurations on the local and peer ends. – Check that the optical modules on the local and peer interfaces are matched, including interface types, rate, wavelengths, and optical powers of optical modules. Check the fiber connected the optical modules and the power of connected optical modules meet the requirement. If the fiber or either of the optical modules does not meet the requirement, replace it. – Check that the auto-negotiation modes on the local and peer interfaces are consistent. If they are inconsistent, run the duplex command to make the two interfaces use the same duplex mode. – Check that the interface configurations such as the MTU, TTL of packets, format of transmitted Ethernet frames, and maximum QoS bandwidth on the local and peer ends are consistent. If they are inconsistent, adjust them to ensure consistency. – Check that the traffic is normal. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 30 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer 3. Check that the fiber is properly and correctly installed. This means that the fiber is connected to the correct transmit optical module and receive optical module. 4. Run the loopback command to check that the fiber between the local and peer ends is not damaged. If the physical layer on the local interface is Up after the loopback local command is run, the local interface is normal. If the physical layer on the peer interface is Up after the loopback remote command is run, the peer interface is normal. It indicates that the fiber between the local and peer interfaces is damaged. Replace the fiber. 5. l If the fault persists after the preceding operations are complete, contact Huawei technical support personnel. If an Ethernet interface cannot be pinged, perform the following operations: 1. Check that the local end is correctly connected to the peer end. Observe the Link indicator on the LPU where the local Ethernet interface resides. If the indicator is on, the link works properly. If the indicator is off, check the optical module, interface, fiber, and the device. 2. Check that the auto-negotiation modes on the local and peer Ethernet interfaces are consistent. 3. Check that the IP address of the local Ethernet interface belongs to the same subnet as that of the peer Ethernet interface. This means that the two IP addresses must have the same network address and different host addresses. If the two IP addresses do not belong to the same subnet, reconfigure the IP addresses. 4. Check that the link layer protocols on the local and peer ends are consistent. Reliable communication between two Ethernet devices is available only when they use the same link layer protocol. 5. If the fault persists after the preceding operations are complete, contact Huawei technical support personnel. 4.2 Checking POS Interfaces This section describes how to check the link layer on POS interfaces. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Procedure Step 1 Run the display interface brief command to view brief information about POS interfaces, including the physical status, link layer protocol status, bandwidth usage, and statistics about incorrect packets. <HUAWEI> display interface brief | include Pos PHY: Physical *down: administratively down ^down: standby (l): loopback (s): spoofing (b): BFD down (e): EFM down (d): Dampening Suppressed InUti/OutUti: input utility/output utility Interface PHY Protocol InUti OutUti inErrors outErrors Pos1/0/0 up up 0.01% 0.01% 3795064053 0 Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 31 HUAWEI NetEngine80E/40E Router Commissioning Guide Pos1/0/1 Pos1/0/2 Pos1/0/3 4 Commissioning the Link Layer down down down down down down 0% 0% 0% 0% 0% 0% 343911292 343913408 343915353 0 0 0 This command can quickly display the physical status and link layer protocol status of all POS interfaces on the NE80E/40E. Step 2 Run the display interface pos command to view the physical status, link layer protocol status, clock mode on a POS interface. For example: <HUAWEI> display interface pos 1/0/0 Pos1/0/0 current state : UP Line protocol current state : UP Last line protocol up time : 2011-03-12 22:16:41 Description:HUAWEI, Quidway Series, Pos1/0/0 Interface Route Port,The Maximum Transmit Unit is 4470, Hold timer is 10(sec) Internet Address is 1.0.0.1/24 Link layer protocol is PPP LCP opened, IPCP opened The Vendor PN is FTRJ8519P1BNL-HW The Vendor Name is FINISAR CORP.

If the alarm count and error count are not 0, run the command several times to check whether the counts increase. Or, run the reset counters interface command to clear the statistics and then run the command several times. Step 3 Run the ping command to test POS link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. ms ms ms ms 32 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting If the physical status of a POS interface does not go Up after it is connected, perform the following operations: 1. Check that the local and peer POS interfaces are enabled, the input and output optical power of the interfaces are normal, and there are no SDH alarms. Run the display interface pos [ interface-number ] command. l If the value of the current state field is Administratively down, the POS interface is not enabled. Run the undo shutdown command in the interface view. l If the output optical power is not within the allowed range, replace the optical module. l If the input optical power is smaller than the receiver sensitivity, adjust the link or replace the peer optical module. l If the values of the fields under the SDH alarm field are not none and B1, B2, and B3 error code counts displayed under the SDH error fields increase, note the following points: – If B1, B2, and B3 error code counts all increase, check the direct link between the optical modules as well as these modules on the two ends. If the link is a WDM link, ensure that it is stable. – If only the B3 error code count increases, check the link directly connecting the peer device and an SDH device because this problem often occurs when a routing device is connected to an SDH device. If the link between the concerned SDH devices is a WDM link, you also need to check the entire WDM link to ensure stable transmission. If the fault persists, go to Step 2. 2. Check that the fiber and optical modules are properly installed. An optical module or a fiber connector has a fastener. If you hear a click when installing the fiber or an optical module, the fiber or optical module is properly installed. If the fault persists, go to Step 3. 3. Check that the fiber is connected to the correct transmit optical module and receive optical module. Remove the fiber and connect it to a different module of the original interface on each end (for example, if the fiber is connected to the transmit optical module of an interface on the local end, remove it and then connect the fiber to the receive optical module of that interface on the local end). If the fault is not rectified, restore the original fiber connection. If the fault persists, go to Step 4. 4. Use a fiber to perform local loopback. Use a good fiber to connect the transmit and receive optical modules of the local interface. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 33 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer l If the physical layer is Up and SDH alarms are all cleared and B1, B2, and B3 error code counts do not increase on the interface, the local optical modules and the board where the interface resides work properly. You need to check the link and the peer device. l If the physical layer is not Up, the local optical modules or the board where the modules reside works abnormally. Switch the services of the board or the concerned interface to another board and then replace the optical modules or the board to see if the fault will be rectified. NOTE Before using a fiber to perform local loopback, run the clock master command to set the clock mode of an interface to master. If the fault persists, go to Step 5. 5. Collect the following information and contact Huawei technical support personnel: l Results of the preceding operation procedure l Configuration files, log files, and alarm files of the NE80E/40E 4.3 Checking CPOS Interfaces This section describes how to check the link layer on CPOS interfaces. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Procedure Step 1 Run the display controller cpos command to check the status of a CPOS interface. For example: <HUAWEI> display controller cpos 1/0/0 Cpos1/0/0 current state : UP Description : Cpos1/0/0 Interface The Vendor Name is AGILENT The Vendor PN is QFCT-5736TP Port BW: 155M, Transceiver max BW: 155M, Transceiver Mode: SingleMode WaveLengh: 1310nm, Transmission Distance: 15km Physical layer is Packet Over SDH clock master, Multiplex AU-4, loopback none TX:Flag J0: "NetEngine ", Flag J1: "NetEngine ", Flag C2: 2(0x2) RX:Flag J0: "NetEngine ", Flag J1: "NetEngine ", Flag C2: 2(0x2) section layer: alarm: none error: B1 0 line layer: alarm: none error: B2 0 REI 0 path layer: alarm: none error: B3 0 REI 0 The setted port-tx-enabling delay time is: 0 ms The remanent time of enabling port-tx is: 0 ms As shown by the characters displayed in boldface, the CPOS interface status is UP when the CPOS interface is correctly configured, and no alarms or errors are displayed. If the alarm count and error count are not 0, run the command several times to check whether the counts increase. Or, clear the statistics and then run the command several times. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 34 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Step 2 Run the display interface serial command to view the operation status of and statistics on the serial interface. For example: <HUAWEI> display interface serial 1/0/0/0:0 Serial1/0/0/0:0 current state : Up Line protocol current state : Up Description:HUAWEI, Quidway Series, Serial1/0/0/0:0 Interface Route Port,The Maximum Transmit Unit is 1500, Hold timer is 10(sec) Derived from CPOS 1/0/0 e1 1, Timeslot(s) Used: 1-31, baudrate is 1984000 bps Internet protocol processing : enabled Link layer protocol is PPP LCP initial clock master, loopback none CRC: CRC-32 Current system time: 2011-01-21 17:45:40 Framer LOS Alarm Status(0-NONE 1-ALARM): 0 Framer LOF Alarm Status(0-NONE 1-ALARM): 1 Framer PAIS Alarm Status(0-NONE 1-ALARM): 1 Framer PRDI Alarm Status(0-NONE 1-ALARM): 0 PSN2TDM PW Alarm status(0-NONE 1-RDI 2-AIS): 0 Statistics last cleared:2011-01-21 10:18:07 09:25:21 Traffic statistics: Input: 0 packets Output: 0 packets Output error: 0 underrun count, 0 overrun count 0 misorder packets, 0 malformed packets 0 los packets, 0 dummy packets ES: 0, SES: 0, UAS: 0 Input bandwidth utilization : 0.00% Output bandwidth utilization : 0.00% As shown by the characters displayed in boldface, the physical status and link layer protocol status of the serial interface are Up when the serial interface channelized from a CPOS interface is correctly configured. If the IP addresses of the serial interfaces on both ends of the link and routes are correctly configured, the network layer protocol status on the local serial interface is enabled. Step 3 Run the ping command to test CPOS link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting If serial interfaces on the two ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: 1. Issue 02 (2011-09-10) Check the physical status of the CPOS interfaces on both ends. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 35 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer (1) Check the type of fiber connecting the CPOS interfaces and whether the fiber is correctly installed. (2) If the fiber is correctly and properly installed, run the undo shutdown command and then the display this interface command on the local serial interface. You can see that the physical status of the interface is Up. (3) If the physical status of the interface is Down, run the clock master command and then the loopback local command on the CPOS interface on each end. If the physical status of the interface on each end is Up, the fiber may be faulty. If the physical status of the interface on either end is still Down, the board where the interface resides may be faulty. In this case, seek technical support. 2. Check that the link layer protocol configurations on both ends of the link are consistent. (1) Run the display this interface command on the serial interface on each end to view the configured link layer protocol. If PPP is configured on one end and HDLC is configured on the other end, change the link layer protocol configurations to ensure consistency on both ends. (2) Check whether the MTUs on the serial interfaces on both ends are the same. Run the display interface interface-type interface-number command on the serial interface on each end to view the MTU. If the MTUs on the serial interfaces on the two ends are not the same, run the mtu command on one end to ensure MTU consistency. If the fault persists, proceed with the following operations. If the link layer protocol is HDLC, go to Step 3. If the link layer protocol is PPP, go to Step 4. 3. Check that the HDLC configuration is correct. (1) Check whether IP address unnumbered is configured on the serial interfaces on both ends. Run the display this command on the serial interface on each end to check whether the ip address unnumbered interface interface-type interface-number command has been configured. If that command has been configured, ensure that the IP address borrower can learn the route to its peer. Otherwise, the ping operation will fail. (2) Check whether the same hold time is configured on the two ends. Run the display interface interface-type interface-number command on the serial interface on each end to view the value of the hold timer field. If different values of the hold timer field are configured on the two ends, run the timer hold command on one end to change the field value and ensure value consistency. If the fault persists, contact Huawei technical support personnel. 4. Check that PPP works properly between the serial interfaces on the two ends. Verify that IP addresses are correctly configured for the serial interfaces on the two ends. Then, run the display this interface command on the serial interface on each end. If the command output shows that the link layer protocol is Down, perform the following operations to find the reason why PPP is not started: (1) Check whether Link Control Protocol (LCP) negotiation goes smoothly. LCP negotiation is the first phase of the setup of a PPP connection. If LCP negotiation between the two ends succeeds, a link will be set up and some basic link characteristics on the two ends will reach consistency. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 36 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Run the display this interface command on the serial interface on either end. The command output shows the LCP negotiation status. If the status is opened, LCP negotiation is completed. Otherwise, LCP negotiation has not been completed yet. (2) Check whether Internet Protocol Control Protocol (IPCP) negotiation goes smoothly. IPCP negotiation follows successful LCP negotiation and authentication. In this phase, the IP addresses of serial interfaces are negotiated between the two ends. As a prerequisite, the serial interfaces on the two ends must be configured with IP addresses. Otherwise, the IPCP negotiation status cannot be checked. After confirming that the IP addresses configured on the serial interfaces on the two ends are correct, run the display this interface command on the serial interface on either end. The command output shows the IPCP negotiation status. If the status is opened, IPCP negotiation is completed. Otherwise, IPCP negotiation has not been completed yet. 5. Check statistics on the serial interfaces on the two ends. If PPP is started after LCP and IPCP negotiation but the serial interfaces on the two ends still cannot ping each other, check statistics on the serial interfaces to find if the transmission of other types of packets is faulty. NOTE Authentication is required between LCP negotiation and IPCP negotiation, which can be Password Authentication Protocol (PAP) authentication or Challenge Handshake Authentication Protocol (CHAP) authentication. If authentication fails, the link is disconnected. It is supposed that no authentication is configured in the preceding steps. If authentication is configured in real-world situations, check that the user name and password of the authenticated are correct. In addition, to check that the authentication messages are correctly transceived, enable debugging and check the statistics on the interface. 6. If the fault persists, contact Huawei technical support personnel. 4.4 Checking E-Carrier and T-Carrier Interfaces This section describes how to check the link layer on E-Carrier and T-Carrier interfaces. In this section, a CE1 interface is used as an example. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Procedure Step 1 Run the display controller e1 command to check the status of a CE1 interface.

Step 2 Run the display interface serial command to view the operation status of and statistics on the serial interface. For example: <HUAWEI> display interface serial 1/0/0/0:0 Serial1/0/0/0:0 current state : Up Line protocol current state : Up Description:HUAWEI, Quidway Series, Serial1/0/0/0:0 Interface Route Port,The Maximum Transmit Unit is 1500, Hold timer is 10(sec) Derived from CPOS 1/0/0 e1 1, Timeslot(s) Used: 1-31, baudrate is 1984000 bps Internet protocol processing : enabled Link layer protocol is PPP LCP initial clock master, loopback none CRC: CRC-32 Current system time: 2011-01-21 17:45:40 Framer LOS Alarm Status(0-NONE 1-ALARM): 0 Framer LOF Alarm Status(0-NONE 1-ALARM): 1 Framer PAIS Alarm Status(0-NONE 1-ALARM): 1 Framer PRDI Alarm Status(0-NONE 1-ALARM): 0 PSN2TDM PW Alarm status(0-NONE 1-RDI 2-AIS): 0 Statistics last cleared:2011-01-21 10:18:07 09:25:21 Traffic statistics: Input: 0 packets Output: 0 packets Output error: 0 underrun count, 0 overrun count 0 misorder packets, 0 malformed packets 0 los packets, 0 dummy packets ES: 0, SES: 0, UAS: 0 Input bandwidth utilization : 0.00% Output bandwidth utilization : 0.00% As shown by the characters displayed in boldface, the physical status and link layer protocol status of the serial interface are Up when the serial interface channelized from a CE1 interface is correctly configured. If the IP addresses of the serial interfaces on both ends of the link and routes are correctly configured, the network layer protocol status on the local serial interface is enabled. Step 3 Run the ping command to test CE1 link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting If E-carrier or T-carrier interfaces on both ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 38 HUAWEI NetEngine80E/40E Router Commissioning Guide 1. 4 Commissioning the Link Layer Check that the physical layer is Up. (1) Run the display controller e1 command to view interface information on each end. If the physical status is displayed as Administratively Down, the shutdown command has been run on the interface. Run the undo shutdown command to enable the interface. If the physical status is displayed as Down, check the following items: l Fiber is properly connected to the local interface and the indicator for the interface is in a normal state. l Fiber is properly connected to the peer interface. Run the display this interface command in the interface view to check if the physical status of the peer interface is Administratively Down and if loopback is configured on the peer interface. l Interface configurations, such as the operation mode and line coding/decoding format, on the two ends are consistent, and the clock modes configured on the two ends are correct. (2) If the fault persists, run the link-protocol command in the CE1, serial, CT1, E3, or CT3 interface view to set the link layer protocol to HDLC and then run the loopback command in the CE1, CT1, E3, or CT3 interface view. If the physical status of the interface is Up, the hardware on the local end works properly. The problem lies in the cable, and you need to replace the cable. If the physical status of the interface is Down, the board where the interface resides is faulty. The board needs to be repaired. 2. Check that the link layer is Up. If the link status is Down, run the display interface serial command on each end to check the link status. (1) Check whether the two ends use the same link layer protocol. The link layer can go Up only when the two ends of the link use the same link layer protocol. (2) If the physical layer is Up, check whether correct IP addresses are configured for the interfaces on the two ends. (3) If the LCP negotiation status is not opened, LCP negotiation has not been completed yet. LCP negotiation is completed only when the LCP negotiation status is opened. (4) If the LCP negotiation status is opened and the IPCP negotiation status is not opened, IPCP negotiation has not been completed. IPCP negotiation is completed only when the IPCP negotiation status is opened. 3. If the interfaces on the two ends of the link still cannot ping each other even if all configurations are correct, run the display interface serial command to view statistics on the interfaces and contact Huawei technical support personnel. 4.5 Checking ATM Interfaces This section describes how to check the link layer on ATM interfaces. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 39 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Procedure Step 1 Run the display interface atm command to check the configurations, physical status, and link layer protocol status on an ATM interface. For example: <HUAWEI> display interface atm 1/0/0 Atm1/0/0 current state : UP Line protocol current state : UP Last line protocol up time: 2010-11-03, 17:24:24 Description : Atm1/0/0 Interface Route Port, The Maximum Transmit Unit is 1500 Internet protocol processing : disabled AAL enabled: AAL5, Maximum VCs: 2048 VCs on main-interface: 1 (Total VCs: 1) VPs on main-interface: 0 (Total VPs: 1 ) The Vendor Name is FINISAR CORP. , The Vendor PN is FTRJ1321P1BTL Transceiver BW: 2.5G, Transceiver Mode: Single Mode WaveLength: 1310nm, Transmission Distance: 5km Rx Optical Power: -24.95dBm, Tx Optical Power: -1.99dBm Physical layer is Packet Over SDH UBR: 1, CBR: 0, VBR: 0, USED BandWidth: 0Kbps VPI Max: 255, VCI Max: 2047 Scramble enabled, clock master, CRC-32, loopback: none Flag: J0 "NetEngine " Flag: J1 "NetEngine " Flag: C2 19(0x13) SDH alarm: section layer: OOF LOF LOS line layer: AIS path layer: AIS RDI SDH error: section layer: B1: 24 line layer: B2: 0 M1: 0 path layer: B3: 0 G1: 0 Statistics last cleared:never Send good cell: 0 cells Send idle cell: 25099462530 cells Receive idle cell: 0 cells Receive corrected cell: 0 Receive uncorrected cell: 97 Dropped receive cell: 0 cells Last dropped receive cell connection: 0/0 Last 30 seconds input rate: 0 bits/sec, 0 Packets/sec Last 30 seconds output rate: 0 bits/sec, 0 Packets/sec Input: 0 Bytes, 0 Packets Output: 0 Bytes, 0 Packets As shown by the characters displayed in boldface, the physical status and link layer protocol status of the ATM interface are UP when the ATM interface is correctly configured. The command output also displays the frame format, clock mode, statistics interval, and whether scrambling is enabled. Step 2 Run the display atm map-info command to check whether information in the upper layer protocol mapping table is correct. <HUAWEI> display atm map-info Atm1/0/0, PVC 1/33, IP, State UP100.11.1.1, vlink 1 Atm1/0/0, PVC 2/101, ETH, Virtual-Ethernet1/0/0, UP Step 3 Run the display atm pvc-info command to view PVC information. <HUAWEI> display atm pvc-info VPI/VCI |STATE|PVC-NAME |INDEX |ENCAP|PROT |INTERFACE --------|-----|----------------|--------|-----|-----|------------------0/40 |UP | |1 |SNAP |IP |Atm1/0/0 (UP) 0/60 |UP |to_adsl_a |2 |SNAP |ETH |Atm1/0/0.1 (UP) VPI/VCI |STATE|PVC-NAME |INDEX |ENCAP|PROT |INTERFACE --------|-----|----------------|--------|-----|-----|------------------1/10 |UP | |2 |SNAP |None |Atm2/0/0.1 (UP) 1/100 |UP | |1 |SNAP |IP |Atm2/0/0 (UP) Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 40 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Check the fields displayed in boldface in the preceding information to see if the PVC status is Up, the application mode is correct (in the PROT field, IP indicates IPoA, and ETH indicates IPoEoA), and the interface where the PVC resides is Up. Step 4 Run the display atm pvp-info command to view PVP information. <HUAWEI> display atm pvp-info VPI | STATE | PVP-NAME | INDEX | ENCAP | PORT | INTERFACE -------------------------------------------------------------------10 | UP | | 0 | AAL0 | None | Atm2/0/0.1(UP) Check the fields displayed in boldface in the preceding information to see if the PVP status is Up, the application mode is correct (in the PROT field, IP indicates IPoA, and ETH indicates IPoEoA), and the interface where the PVP resides is Up. Step 5 Run the ping command to test ATM link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting If ATM interfaces on the two ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: 1. Enter the ATM interface view and run the display this interface command to check the physical status and link layer protocol status of the ATM interface on each end. If both status are Down, go to Step 2. If they are Up, go to Step 3. 2. Check the physical status, link layer protocol status, and clock mode on the ATM interface on each end. l Check that fiber is correctly connected to the ATM interface. An ATM interface is connected to two fibers. One is used for signal receiving and connected to the receive optical module, and the other is used for signal transmission and connected to the transmit optical module. Ensure that the fiber connections are correct. If the fiber connections are incorrect, the physical status of the ATM interface is Down. If the fiber connections are correct, the Link indicator on the ATM interface is On. l The fiber connected to an ATM interface can be multimode fiber or single-mode fiber. If some ping packets are lost or the ping fails, check whether the ATM interfaces on the two ends are both multimode or single-mode interfaces. In most cases, a multimode interface and a single-mode interface that are directly connected can communicate with each other, but sometimes a great number of packets will be discarded or CRC errors will occur. l If two NE80E/40Es are directly connected, check whether the internal clocks are not enabled on two ATM interfaces. By default, one NE80E/40E uses a line clock. If the Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 41 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer NE80E/40Es are directly connected or connected through a WDM device, run the clock master command on one of the NE80E/40Es to provide an internal clock. l If the physical status of the interface remains Down, contact Huawei technical support personnel. 3. Check that the PVCs on the interfaces on both ends are the same. Since ATM interfaces use PVCs for communication, the PVCs on the interfaces on both ends must be the same. For IPoA, check that the protocol address mapping is correctly configured. If two NE80E/40Es are directly connected, the PVC mapped from the local to the peer IP address must be the same as the PVC mapped from the peer to the local IP address. Check whether the authentication configurations on both ends are the same for PPPoA. 4. Check that the configurations and protocol types on the ATM interfaces on the two ends are the same. Check that the protocols (IPoA, PPPoA, IPoEoA, or PPPoEoA) over the PVCs on the ATM interfaces on the two ends are the same. If the routing protocol over ATM is Open Shortest Path First (OSPF), the mapping information configured on the ATM interfaces must contain broadcast. If the ATM interfaces on the two ends can use short packets, but not long packets, to ping each other, check whether the MTUs on the ATM interfaces are the same. 5. If the ATM interfaces on the two ends still cannot communicate with each other, contact Huawei technical support personnel. 4.6 Checking FR Interfaces This section describes how to check the link layer on Frame Relay (FR) interfaces. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Procedure Step 1 Run the display fr interface command to view the physical status and link layer protocol status of FR interfaces and whether the FR interfaces are DTE or DCE interfaces. The command output also includes the type and link layer protocol status of the sub-interface. <HUAWEI> display fr interface Pos1/0/0, DCE, physical up, protocol up Pos1/0/0.1, point-to-point, protocol up Check the information displayed in boldface in the preceding information to ensure that: l The working mode of the FR interface is correct. DTE indicates the working mode of the interface on the user side; DCE indicates the working mode of the interface on the network side. l The physical status and link layer protocol status are Up. l The network layer protocol is Up. l The sub-interface type is point-to-point. Step 2 Run the display fr map-info command to check the FR address mapping table. <HUAWEI> display fr map-info Map Statistics for interface Pos1/0/0 (DCE) DLCI 20, Point-to-Point DLCI, Pos1/0/0.1 created at: 2010/02/12 11:17:37, status: ACTIVE Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 42 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Check the information displayed in boldface in the preceding information to ensure that the configured Data-Link Connection Identifier (DLCI) is correct and dynamic address mapping works properly (ACTIVE). Step 3 Run the ping command to test FR link connectivity. For example: <HUAWEI> ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms In normal situations, the ping operation should succeed. ----End Troubleshooting If the physical status of an FR interface is Down, check whether the interface is properly connected to a cable. If the network layer protocol status is Down, check whether no DLCI is configured on the FR interface or its peer interface or the DLCIs configured on both ends are not the same. After changing the link layer configuration of an FR interface, run the shutdown command and then the undo shutdown command to restart the interface and make the configuration take effect. When configuring a DLCI on a sub-interface, you must shut down the sub-interface, configure a DLCI on the sub-interface, and then restart the sub-interface to make the configuration take effect. 4.7 Checking the Optical Power of Interfaces You need to check whether the optical power of SFP optical modules meets requirements. If the output optical power of SFP optical modules on the boards of the NE80E/40E does not meet requirements, packets will be lost and communication will be interrupted on the network layer. Prerequisite 3 Checking the Hardware is complete and the NE80E/40E works properly. Procedure Step 1 Run the display interface interface-type interface-number command to view the operation status and statistics on each of two connected interfaces. Go on with the subsequent commissioning, if the maximum transmission distance and central wavelength of the optical modules on the two connected interfaces are consistent and the input optical power and output optical power of the optical modules are within the allowed range. In the following example, the display on a POS interface is used.

Check the output optical power of optical modules on the two ends against the "List of LPU Interface Attributes" to determine if the output optical power is within the allowed range. NOTE For details about the "List of LPU Interface Attributes", see the attachment. The output optical power of the local optical module must meet the following requirements: l The minimum output optical power must be higher than the receiver sensitivity of the optical module. Otherwise, the peer end cannot receive signals. l The maximum output optical power must be lower than the overload power of the optical module. Otherwise, the optical module may be damaged. ----End Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 44 HUAWEI NetEngine80E/40E Router Commissioning Guide 4 Commissioning the Link Layer Troubleshooting If the output optical power of an optical module is beyond the allowed range, replace the optical module.

Check that static route parameters are correctly configured. Run the display current-configuration | include route-static command to check whether static route parameters are correct and destination addresses, outbound interfaces, and next hops of IPv4 static routes are configured. 2. Check that the precedence of static routes is correctly configured. Run the display ip routing-table command to check the precedence of static routes in the IPv4 routing table. The precedence of static routes is 60 by default, being lower than OSPF routes (10) and IS-IS routes (15). Therefore, if OSPF or IS-IS is also configured, to make static routes take effect, run the ip route-static default-preference preference command to set the default precedence of static routes to be higher than that of OSPF routes or IS-IS routes before configuring static routes. The smaller the preference value, the higher the preference. 3. If the fault persists after the preceding operations are complete, contact Huawei technical support personnel. 5.2 Commissioning OSPF Routes Users can choose to configure a routing protocol based on the actual network planning.

Figure 5-3 Typical networking for commissioning OSPF routes 1.1.1.1/32 Console PC 2.2.2.2/32 192.168.1.1 / 24 GE1/0/0 network GE2/0/0 GE3/0/0 192.168.1.2 / 24 192.167.1.10 / 24 RouterA RouterB Procedure Step 1 Run the display ospf peer command on the commissioning device to view its OSPF neighbor information. <HUAWEI> display ospf peer OSPF Process 1 with Router ID 1.1.1.1 Neighbors Area 0.0.0.0 interface 192.168.1.1(GigabitEthernet1/0/0)'s neighbors Router ID: 2.2.2.2 Address: 192.168.1.2 State: Full Mode:Nbr is Slave Priority: 1 DR: 192.168.1.1 BDR: 192.168.1.2 MTU: 0 Dead timer due in 35 sec Retrans timer interval: 5 Neighbor is up for 00:00:05 Authentication Sequence: [ 0 ] The field in bold in the command output shows the OSPF neighbor information. Then check the number of neighbors, whether or not the neighbor relationships are in the Full state (indicating that the neighbors have finished LSDB synchronization and established the Full adjacency) and whether or not the neighbors can remain in the Up state for a long time. If a neighbor stays in the Up state for a short period of time, it indicates that the OSPF neighbor relationship has been recently interrupted. Pay attention to such a symptom. Step 2 Run the display ospf routing command on the commissioning device to view information about the OSPF routing table. Intra-area OSPF routes: <HUAWEI> display ospf routing OSPF Process 1 with Router ID 1.1.1.1 Routing Tables Routing for Network Destination Cost 192.168.1.0/24 1 2.2.2.2/32 1 Issue 02 (2011-09-10) Type transit Stub NextHop 192.168.1.1 192.168.1.2 AdvRouter 1.1.1.1 2.2.2.2 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 51 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols Step 5 Run the display ospf error command on the commissioning device to view OSPF errors. <HUAWEI> display ospf error OSPF Process 1 with Router ID 1.1.1.1 OSPF error statistics General packet errors: 0 : IP: received my own packet 0 : Bad version 0 : Bad area id 0 : Bad virtual link 0 : Bad authentication key 0 : Packet size > ip length 0 : Interface down 0 0 0 0 0 0 0 : : : : : : : Bad packet Bad checksum Drop on unnumbered interface Bad authentication type Packet too small Transmit error Unknown neighbor HELLO packet errors: 0 : Netmask mismatch 0 : Dead timer mismatch 0 : Router id confusion 0 : NBMA neighbor unknown 0 0 0 0 : : : : Hello timer mismatch Extern option mismatch Virtual neighbor unknown Invalid Source Address 0 0 : Router id confusion : Unknown LSA type 0 : Unknown LSA type LS REQ packet errors: 0 : Neighbor state low 0 : Bad request 0 : Empty request LS UPD packet errors: 0 : Neighbor state low 0 : LSA checksum bad 0 : Unknown LSA type 0 0 : Newer self-generate LSA : Received less recent LSA Opaque errors: 0 : 9-out of flooding scope 0 : 11-out of flooding scope type 0 0 : 10-out of flooding scope Unkown TLV DD packet errors: 0 : Neighbor state low 0 : Extern option mismatch 0 : MTU option mismatch LS ACK packet errors: 0 : Neighbor state low Retransmission for packet over Limitation errors: 0 : Number for DD Packet 0 : Number for Update Packet 0 : Number for Request Packet Receive Grace LSA errors: 0 : Number of invalid LSAs 0 : Number of wrong period LSAs Configuration errors: 0 : Tunnel cost mistake 0 : Number of policy failed LSAs To locate OSPF faults, you can run this command to view OSPF error information. OSPF error information is a basis for OSPF fault diagnosis. Step 6 Run the ping command on the commissioning device to test the availability of OSPF routes. <HUAWEI> ping 192.167.1.10 PING 192.167.1.10: 56 data Reply from 192.167.1.10: Reply from 192.167.1.10: Reply from 192.167.1.10: Reply from 192.167.1.10: Reply from 192.167.1.10: bytes, press CTRL_C bytes=56 Sequence=1 bytes=56 Sequence=2 bytes=56 Sequence=3 bytes=56 Sequence=4 bytes=56 Sequence=5 to break ttl=255 time=3 ttl=255 time=3 ttl=255 time=2 ttl=255 time=3 ttl=255 time=3 ms ms ms ms ms --- 192.167.1.10 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 2/2/3 ms Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 52 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols The preceding command output shows that the commissioning device has a reachable OSPF route to the network connected to Router B. ----End Troubleshooting If the OSPF neighbor relationship is Down after OSPF is configured, complete the following: 1. Check logs to find the cause of the Down OSPF neighbor relationship. Run the display logbuffer command to view the following log information: NBR_DOWN_REASON(l): Neighbor state leaves full or changed to Down. (ProcessId= [USHORT], NeighborRouterId=[IPADDR], NeighborAreaId=[ULONG], NeighborInterface=[STRING],NeighborDownImmediate reason=[STRING], NeighborDownPrimeReason=[STRING], NeighborChangeTime=[STRING]) Check the NeighborDownImmediate reason field which records the cause of the Down OSPF neighbor relationship. Possible causes are as follows: l Neighbor Down Due to Inactivity It indicates that the local end does not receive any Hello packet from its neighbor within the deadtime, and hence the OSPF neighbor relationship becomes Down. In this case, go to Step 2. l Neighbor Down Due to Kill Neighbor It indicates that the interface or BFD session is in the Down state, or the reset ospf process command is run and hence the OSPF neighbor relationship becomes Down. In this case, check the NeighborDownPrimeReason field to find the specific cause of the fault. – If the NeighborDownPrimeReason field displays Physical Interface State Change, it indicates that the interface status has changed. In this case, run the display interface [ interface-type [ interface-number ] ] command to check the interface status, and then rectify the interface fault. – If the NeighborDownPrimeReason field displays OSPF Process Reset, it indicates that the reset ospf process command has been executed. Whether or not this command has been run can be ensured by checking the operation records or log information. – If the NeighborDownPrimeReason field displays BFD Session Down, it indicates that the BFD session status has become Down. In this case, rectify the BFD fault. l Neighbor Down Due to 1-Wayhello Received or Neighbor Down Due to SequenceNum Mismatch It indicates that the OSPF status on the remote end becomes Down before the remote end sends a 1-Way Hello packet to the local end, causing the OSPF status on the local end to become Down as well. In this case, rectify the fault on the remote end. l In other cases, go to Step 9. 2. Check that the link between the two ends works normally. Check that the link between the two ends is working normally, including the transmission devices. If the link works properly, go to Step 3. 3. Check that the CPU usage is within the normal range. Check whether or not the CPU usage on the MPU or LPU of the faulty device is too high. If the CPU usage is too high, OSPF fails to receive and send protocol packets, causing the Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 53 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols neighbor relationship to flap. In this case, rectify the high CPU usage fault. If the CPU usage is within the normal range, go to Step 4. 4. Check that the interface status is Up. Run the display interface [ interface-type [ interface-number ] ] command to check the physical status of the interface. If the physical status of the interface is Down, rectify the interface fault. If the physical status of the interface is Up, run the display ospf interface command to check that the OSPF status of the interface is Up. <HUAWEI> display ospf interface OSPF Process 1 with Router ID 1.1.1.1 Interfaces Area: 0.0.0.0 IP Address Type (MPLS TE not enabled) State Cost 192.168.1.1 Broadcast Pri DR 1 192.168.1.1 BDR DR 1 0.0.0.0 l If the OSPF status of the interface is Down, run the display ospf cumulative command to check whether or not the number of interfaces enabled with OSPF in the OSPF process exceeds the limit. If so, reduce the number of interfaces enabled with OSPF. <HUAWEI> display ospf cumulative OSPF Process 1 with Router ID 1.1.1.1 Cumulations IO Statistics Type Input Output Hello 28310 134625 DB Description 32 25 Link-State Req 17 9 Link-State Update 1051 657 Link-State Ack 606 982 ASE: (Disabled) LSAs originated by this router Router: 1 Network: 11 Sum-Net: 0 Sum-Asbr: 0 External: 0 NSSA: 0 Opq-Link: 0 Opq-Area: 20 Opq-As: 0 LSAs Originated: 32 LSAs Received: 1448 Routing Table: Intra Area: 11 Inter Area: 0 ASE: 0 Up Interface Cumulate: 6 Neighbor Cumulate: ======================================================= Neighbor cumulative data.

Issue 02 (2011-09-10) Check that the IP addresses of the two ends are on the same network segment. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 54 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols l If the IP addresses of the two ends are on different network segments, modify the IP address of one end. l If the IP addresses of the two ends are on the same network segment, go to Step 6. 6. Check that MTUs of the interfaces on both ends are consistent. If ospf mtu-enable is enabled on the interfaces, the interface MTUs must be consistent. Otherwise, OSPF neighbors cannot negotiate with each other successfully. l If MTUs of the interfaces on both ends are inconsistent, run the mtu mtu command in the interface view to change MTUs of the interfaces to be consistent on both ends. l If the MTUs of the interfaces on both ends are consistent, go to Step 7. 7. Check that there is at least one interface whose priority is not 0. On the broadcast and NBMA networks, there should be at least one interface whose priority is not 0, which ensures that a DR is elected correctly. Otherwise, the state of the OSPF neighbor relationship can only reach 2-Way. Run the display ospf interface command to view the interface priority. <HUAWEI> display ospf interface OSPF Process 100 with Router ID 1.1.1.41 Interfaces Area: 0.0.0.0 (MPLS TE not enabled) IP Address Type State Cost BDR 192.168.1.1 Broadcast DR 1 0.0.0.0 8.

If the value of this field continually increases, it indicates that the OSPF authentication types of the two ends that establish the neighbor relationship are different. In this case, you need to set the same authentication type for both ends. l Check the Hello timer mismatch field. If the value of this field continually increases, it indicates that the value of the Hello timers on the two ends that establish the neighbor relationship are different. In this case, you need to check the interface configurations of the two ends and set the same value for their Hello timers. l Check the Dead timer mismatch field. If the value of this field continually increases, it indicates that the value of the dead timers on the two ends that establish the neighbor relationship are different. In this case, you need to check the interface configurations of the two ends and set the same value for their dead timers. l Check the Extern option mismatch field. If the value of this field continually increases, it indicates that the area types of the two ends that establish the neighbor relationship are different (the area type of one device is common area, and that of the other device is stub area or NSSA). In this case, you need to set the same area type for both ends. If the fault persists, proceed to Step 9. 9.

Check that IS-IS can receive and send Hello packets properly. Run the display isis statistics packet [ interface interface-type interface-number ] command to check that IS-IS can normally receive and send Hello packets. NOTE The default interval at which IS-IS sends Hello packets is 10s. Therefore, run this command every 10s to check whether or not the packet statistics increase. On a broadcast interface, IS-IS Hello packets have IS-IS levels, and therefore you can view Hello packet statistics based on the levels of established neighbor relationships. On a P2P interface, IS-IS Hello packets have no IS-IS levels and are recorded as L2 IIH packets. l If the number of received Hello packets does not increase for a certain period, check whether or not packet loss has occurred at the lower layer or at the link between the two ends. l If the number of received Hello packets increases gradually, perform the following operations based on interface types: – If the interfaces on both ends are trunk interfaces, check that the numbers of the trunk member interfaces in the Up state are the same on both ends. – If the interfaces on both ends are not trunk interfaces, go to Step 2. 2. Check that the interface status is Up. Run the display ip interface [ interface-type interface-number ] command to check the status of a specified interface. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 58 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols l If the interface status is not Up, rectify the interface fault. For detailed troubleshooting procedures, see "Interface & Physical Connection Troubleshooting" and "Layer 2 Network Troubleshooting." l If the interface status is Up, go to Step 3. 3. Check the status of IS-IS interfaces. Run the display isis interface command to check the status of the interfaces enabled with IS-IS. l If the interface status is Mtu:Dn/Lnk:Up/IP:Up, run the display currentconfiguration interface interface-type [ interface-number ] command to check the MTUs of the interfaces. Run the display current-configuration configuration isis command to check the LSP length configured in the IS-IS process. On a P2P interface, the LSP length should not be greater than the MTU. On a broadcast interface, the value obtained by subtracting the LSP length from the MTU should be greater than or equal to 3. If these conditions are not met, change the MTU of the interface or the LSP length. l If the interface status is Down, run the display current-configuration configuration isis command to check the configuration of the IS-IS process. Check that the NET is configured in the IS-IS process. If not, configure the NET in the IS-IS process. l If the interface status is Mtu:Up/Lnk:Dn/IP:Dn, check that IS-IS interfaces are configured with IP addresses. l If the interface status is Up, go to Step 4. 4. Check that the IP addresses of the two ends are on the same network segment. l If the IP addresses of the two ends are on different network segments, modify the IP address of one end. l If the IP addresses of the two ends are on the same network segment, go to Step 5. 5. Check that both ends are configured with different system IDs. Run the display current-configuration configuration isis command to check whether or not the system IDs of the two ends are the same. l If the system IDs of the two ends are the same, set different system IDs for each end. l If the system IDs of the two ends are different, go to Step 6. 6. Check that the IS-IS levels of the two ends are consistent. Run the display current-configuration configuration isis | include is-level command to check the levels of the IS-IS processes on both ends. Then, run the display currentconfiguration interface interface-type interface-number | include isis circuit-level command to check whether or not the IS-IS levels of the interfaces at both ends are consistent. The IS-IS neighbor relationship can only be established when the IS-IS levels of the two interfaces are consistent. l If the IS-IS levels of the interfaces at both ends are inconsistent, run the is-level command in the IS-IS view to change the IS-IS level of one end, or run the isis circuitlevel command in the interface view to change the IS-IS level of the interface. l If the IS-IS levels of the interfaces at both ends are consistent, go to Step 7. 7. Check that the area addresses of the two ends are the same. When the area addresses of the two ends are different, the alarm isisAreaMismatch is generated. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 59 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols NOTE If the two ends establish a Level-1 neighbor relationship, ensure that they are both in the same area. An IS-IS process can be configured with a maximum of three area addresses. As long as one of the area addresses of the local IS-IS process is the same as one of the area addresses of the remote IS-IS process, the Level-1 neighbor relationship can be established. When an IS-IS Level-2 neighbor relationship is established between two ends, you do not need to determine whether or not the area addresses of the two ends are the same. l If the area addresses of the two ends are different, run the network-entity command in the IS-IS view to set the same area address for both ends. l If the area addresses of the two ends are the same, go to Step 8. 8. Check that the authentication configurations on the two ends are the same. If the authentication modes configured on the two ends are different, the alarm isisAuthenticationTypeFailure or isisAuthenticationFailure is generated. Run the display current-configuration interface interface-type interface-number | include isis authentication-mode command to check IS-IS authentication configurations on the interfaces of the two ends. l If the authentication modes configured on both are different, run the isis authenticationmode command in the IS-IS interface view on both ends to set the same authentication mode. l If the authentication modes configured on both ends are the same, go to Step 9. 9. Collect the following information and contact Huawei technical support personnel. l Results of the preceding operation procedure l Configuration files, log files, and alarm files of the devices 5.4 Commissioning IBGP Routes Users can choose to configure the BGP routing protocol based on the actual network planning.

Check that the peer router ID does not conflict with the local router ID. Check information about BGP peers to ensure that their router IDs do not conflict. For example, if the IPv4 unicast peer relationship fails to be established, you can run the display bgp peer command to check whether or not the peer router ID conflicts with the local router ID. Use the following command output as an example: <HUAWEI> display BGP local router Local AS number Total number of Peer PrefRcv 8.9.0.8 10000 9.10.0.10 9999 bgp peer ID : 223.5.0.109 : 41976 peers : 12 Peers in established state : 4 V AS MsgRcvd 4 100 1601 4 200 1565 MsgSent 1443 1799 OutQ Up/Down State 0 23:21:56 Established 0 23:15:30 Established NOTE To check information about BGP peers in the BGP-VPNv4 address family or the BGP-VPN instance address family, you can run the display bgp vpnv4 all peer command. l If the peer router ID conflicts with the local router ID, run the router id command in the BGP view to modify the router IDs to agree. Generally, a loopback interface address is used as the local router ID. l If the peer router ID does not conflict with the local router ID, go to Step 4. 4. Check that the peer AS number is configured correctly. Run the display bgp peer command on each end to check that the displayed peer AS number is the same as that of the remote end. <HUAWEI> display bgp peer BGP local router ID : 223.5.0.109 Local AS number : 41976 Total number of peers : 12 Peer PrefRcv 8.9.0.8 10000 9.10.0.10 9999 Peers in established state : 4 V AS MsgRcvd 4 100 1601 4 200 1565 MsgSent 1443 1799 OutQ Up/Down State 0 23:21:56 Established 0 23:15:30 Established NOTE To check information about BGP peers in the BGP-VPNv4 address family or the BGP-VPN instance address family, you can run the display bgp vpnv4 all peer command. l If the peer AS number is configured incorrectly, change it to be the same as that of the remote end.

Check whether or not BGP configurations affect the establishment of the BGP peer relationship. Run the display current-configuration configuration bgp command to check BGP configurations. Table 5-1 Checklist for BGP configurations Item Description peer connect-interface interfacetype interface-number If two ends use loopback interfaces to establish the BGP peer relationship, you need to run the peer connect-interface command to specify the associated loopback interface as the source interface that sends BGP packets. peer valid-ttl-hops hops If the peer valid-ttl-hops hops command is configured, check that the hops value is correct. The valid TTL range of the detected packet is [255 - hops + 1, 255]. hops specifies the hop count between BGP peers, and the hop count between two directly connected devices is 1. NOTE The peer valid-ttl-hops command must be configured on both ends before setting up the BGP session. Issue 02 (2011-09-10) peer route-limit limit If the peer route-limit limit limit command is configured, check whether or not the number of routes sent by the peer exceeds the limit that is specified by limit. If it is exceeded, you need to reduce the number of routes sent from the peer, and run the reset bgp ip-address command to reset the BGP peer relationship and trigger the reestablishment of the BGP peer relationship. peer ignore If the peer ignore command is configured on the peer, it indicates that the peer is not required to establish the BGP peer relationship with the local end temporarily. To establish the BGP peer relationship between the remote peer and local peer, run the undo peer ignore command on the peer. Address family capability Check that the address family capabilities of the two ends match. For example, before establishing the BGP VPNv4 peer relationship, you need to configure the peer enable command in the BGP-VPNv4 address families of the two ends. If the peer enable command is only configured on one end, the BGP peer relationship of the other end is displayed as No neg.

Check whether the interface on which the LDP session is established is shut down. Run the display this command in the interface view. If the command output contains shutdown, the interface is shut down. l If the interface is shut down, run the undo shutdown command in the interface view to start the interface. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 75 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols l If the interface is not shut down, go to Step 2. 2. Check whether commands for deleting MPLS configurations have been executed. Run the display current-configuration command to check whether commands for deleting MPLS configurations have been executed. l If the command output does not contain mpls, MPLS is disabled. l If the command output does not contain mpls ldp, MPLS LDP is disabled. l If the command output does not contain mpls ldp remote peer, the session established with the remote LDP peer has been deleted. l If any command for deleting MPLS configurations has been run, run corresponding commands to restore the deleted configurations. l If no command for deleting MPLS configurations has been run but the fault persists, go to Step 3. 3. Check that routes are available. Run the display ip routing-table command and check the Destination/Mask field in the command output to find out whether there is a route to the peer device. If there is no route to the peer device, the TCP connection cannot be established. l If the route to the peer device is unreachable, follow the procedure described in "The Ping Operation Fails" in the HUAWEI NetEngine80E/40E Router Troubleshooting to rectify the IGP route fault. l If the route to the peer device is reachable, go to Step 4. 4. Check whether an LDP Hello-hold timer expires. Run the display mpls ldp interface command to check that both ends of the LDP session can send Hello messages. It is recommended that the display mpls ldp interface command be run every 3 seconds. If the statistics on sent or received messages remain unchanged, it indicates that the transmission of Hello messages is abnormal, and the Hello-hold timer expires. l If the Hello-hold timer expires, see the troubleshooting of high CPU usage. l If the Hello-hold timer does not expire, go to Step 5. 5. Check whether the LDP Keepalive-hold timer expires. Run the display mpls ldp session command to check that both ends of the LDP session can send Keepalive messages. It is recommended that the display mpls ldp session command be run every 5 seconds. If the statistics on sent or received messages remain unchanged, it indicates that the transmission of Keepalive messages is abnormal, and the Keepalive-hold timer expires. l If the Keepalive-hold timer expires, follow the procedure described in "The Ping Operation Fails" in the HUAWEI NetEngine80E/40E Router Troubleshooting to rectify the fault in message forwarding. l If the Keepalive-hold timer does not expire, go to Step 6. 6.

If there is no route to the original next hop, the BGP route is not advertised, because its next hop is unreachable. Then, find out why there is no route to the original next hop (this fault is generally associated with IGP or static routes). l If the target route is active but not selected, check whether there is a route with a higher protocol preference in the IP routing table. If there is a route with a higher protocol preference, import it into BGP or adjust its protocol preference. If there is no route with a higher protocol preference, contact Huawei technical support personnel. NOTE In the BGP routing table, multiple routes may have the same prefix. One of these routes can be selected at most, and only the selected route is added to the IP routing table and sent to the peer. When an optimal route needs to be selected from among BGP routes and other protocol routes, the route with the highest protocol preference is selected. l If the target route is active but not selected, contact Huawei technical support personnel. NOTE If there are active BGP routes, one of them is preferred. l If the target route is active and selected but there is no information indicating that this route is sent to the remote PE, perform Step 2 to check the outbound policy applied to the local PE. Run the display bgp vpnv4 all routing-table network { mask | mask-length } command on the remote PE to check that it has received the target route. – If the remote PE has received the target route, perform Step 1 again to check whether the next hop of the route is reachable and whether this route is selected. – If the remote PE has not received the target route, perform Step 2 to check the inbound policy applied to the remote PE. 2. Check that the routing policies are configured correctly.

If the BFD is associated with interface status successfully, the Proc interface status field will be displayed as Enable. ----End Troubleshooting If the BFD session cannot become Up, complete the following: 1. Run the display current-configuration configuration bfd-session command to check whether or not BFD session configurations have been committed. l If the commit field is displayed, BFD session configurations have been committed. Then go to Step 2. l If the commit field is not displayed, BFD session configurations have not been committed. In this case, run the commit command in the BFD session view, and then run the display bfd session all command to check that the BFD session is Up. – If the State field is displayed as Up, the BFD session has been created and no action is required. – If the State field is not Up, go to Step 2. 2. Run the display bfd statistics session all slot slot-id command repeatedly to check statistics about BFD packets. l If the Received Packets value does not increase, go to Step 3. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 98 HUAWEI NetEngine80E/40E Router Commissioning Guide 5 Commissioning Services and Protocols l If the Send Packets value does not increase, go to Step 4. l If both the Received Packets and Send Packets values increase properly, go to Step 7. l If none of the Received Packets, Send Packets, Received Bad Packets, and Send Bad Packets values increases, go to Step 5. l If the Down Count value increases, the BFD session flaps. In this case, go to Step 5. 3. Run the display bfd statistics session all slot slot-id command repeatedly to check that the Received Bad Packets value increases properly. l If the Received Bad Packets value increases, the local end receives but discards the BFD packets sent from the remote end. In this case, go to Step 7. l If the Received Bad Packets value does not increase, the local end does not receive BFD packets. In this case, go to Step 5. 4. Run the display bfd statistics session all slot slot-id command repeatedly to check that the Send Bad Packets value increases properly. l If the Send Bad Packets value increases, the BFD packets are sent but discarded. In this case, go to Step 7. l If the Send Bad Packets value does not increase, the local end does not send BFD packets to the remote end. In this case, go to Step 5. 5. Run the display bfd statistics session all slot slot-id command repeatedly. If the BFD session still does not go Up, run the ping command on one end to ping the other end of the BFD session. l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the HUAWEI NetEngine80E/40E Router Troubleshooting to rectify the packet forwarding fault. l If the ping succeeds, go to Step 6. 6. Run the display current-configuration configuration bfd-session command to check the min-tx-interval and min-rx-interval values and determine whether or not the detection time value is larger than the delay value. l If the detection time value is smaller than the delay value, run the detect-multiplier, min-rx-interval, or min-tx-interval command to change the detection time value of the BFD session to be larger than the delay value. l If the detection time value of the BFD session is larger than the delay value, go to Step 7. 7.

Networking Figure 6-1 shows an IP core bearer network that provides multiple services such as 3G, Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), and Internet services. This network consists of two layers, the core layer and the access layer. l Core layer – This layer has two planes with each plane having five nodes that are fully meshed and located in five cities. The nodes on different planes are connected to each other through 10 Gbit/s Ethernet links, and backup paths are provided. – Intermediate System-to-Intermediate System (IS-IS) is used as an Interior Gateway Protocol (IGP) at the core layer, and Traffic Engineering (TE) tunnels are established between Ps on the same plane. l Access layer – Each NGW is dual-homed to two switches. Each switch is separately connected to a PE. The Virtual Router Redundancy Protocol (VRRP) runs between the PEs and switches, ensuring high availability of the link between the two switches. – EBGP peer relationships are established between the PEs and RRs at the core layer. – Remote LDP sessions are established between the PEs at different sites. – The PEs at the same site are connected to each other, switches, and core nodes by GE links. On each PE, the interface connected to a switch is called the user-side interface, and the interface connected to the backbone network is called the network-side interface. The user-side interface contains multiple sub-interfaces with each sub-interface being bound to a VPN instance and serving as the gateway for the corresponding CE. BFD runs on main interfaces.
