About This Document
Purpose
This document describes the NE5000E in terms of its product positioning and features,
architecture, technical specifications, supported FPICs, link features, service features, usage
scenarios, and operation and maintenance.
Note the following precautions:

The encryption algorithms DES/3DES/SKIPJACK/RC2/RSA (RSA-1024 or
lower)/MD2/MD4/MD5 (in digital signature scenarios and password encryption)/SHA1
(in digital signature scenarios) have a low security, which may bring security risks. If
protocols allowed, using more secure encryption algorithms, such as AES/RSA
(RSA-2048 or higher)/SHA2/HMAC-SHA2 is recommended.

Do not set both the start and end characters of a password to "%#%#". This causes the
password to be displayed directly in the configuration file.

To further improve device security, periodically change the password.

1.2 Product Features
1.1 Product Positioning
The Huawei NetEngine5000E Core Router (NE5000E), which has large capacity and high
performance, is developed to meet the requirement of carrier-class reliability. Based on the
powerful versatile routing platform (VRP), the NE5000E provides strong switching
capabilities, dense ports, and high reliability. NE5000Es mainly serve as super-core nodes on
carriers' backbone networks, core nodes on metropolitan area networks (MANs), egresses in
large-scale Internet data centers (IDCs), or core nodes on large-scale enterprise networks.
NE5000E clusters are positioned as super-core nodes on backbone networks, supporting
Layer 3 routing and Multiprotocol Label Switching (MPLS) forwarding. In an NE5000E
cluster, a cluster central chassis (CCC) functions as a level-2 switching module and routing
engine module in a three-stage switch fabric; a cluster line-card chassis (CLC) functions as a
level-1 or level-3 switching module and forwarding module.
The V800R008C10 supports the following types of chassis:


1.2 Product Features
Powerful Forwarding Capability
Designed with a hardware-based forwarding engine, NE5000E series routers support
full-duplex forwarding of IPv4, IPv6, and MPLS packets at the line rate on all interfaces, and
also support access control list (ACL)-based line rate forwarding.
NE5000E series routers support multicast traffic forwarding at the line rate. The hardware of
NE5000E series routers supports two-level multicast traffic replication: replication from
switch fabric units (SFUs) to LPUs and replication from the forwarding engine of an LPU to
associated interfaces.
An LPU can buffer packets, ensuring that no packet is lost in the case of traffic burst.
Well-Designed QoS Mechanism
NE5000E series routers provide the following QoS functions:

Rule-based traffic classification: Traffic can be classified based on Layer 2 rules, Layer 3
rules, and MPLS rules.

Differentiated services: Differentiated services are provided for traffic with different
differentiated services code point (DSCP) values, EXP values, 802.1p priorities, or IP
precedence.

Traffic marking: The DSCP values, EXP values, 802.1p priorities, or IP precedence of
specific traffic can be modified based on a pre-defined policy.

Traffic policing: All traffic or specific traffic on a specified interface can be monitored
for traffic limiting.

Congestion avoidance: Tail drop or weighted random early detection (WRED) is used to
drop certain packets in a queue to prevent queue overflow.

Congestion management: Priority queuing (PQ) and weighted fair queuing (WFQ) are
provided so that fair queue scheduling is ensured and services with a higher priority are
processed preferentially.
These QoS functions ensure different delays, jitter, bandwidth, and packet loss ratios for
different services, such as voice over IP (VoIP) and IPTV services, carried over an IP network.
Robust Security Design
NE5000E series routers provide multiple security features to protect the data of Internet
service providers (ISPs) and users. These features can protect services against denial of
service (DoS) attacks, unauthorized access, and traffic overload on the control plane. The
NE5000E series routers use a distributed structure that separates the data plane from the
control plane, providing industry-leading security performance.
NE5000E series routers provide the following security features:

Three user authentication modes: local authentication, Remote Authentication Dial In
User Service (RADIUS) authentication, and Huawei Terminal Access Controller Access
Control System (HWTACACS) authentication

Hardware-based packet filtering and sampling, which ensures high performance and high
scalability

Excellent Scalability and Rollback Capability
NE5000E series routers have excellent scalability and rollback capability:

An NE5000E single chassis can be smoothly expanded to a CCC-0, CCC-1, or CCC-2
system.

A CCC-0 system can be smoothly expanded to a CCC-1 or CCC-2 system.

A CCC-1 system can be smoothly expanded to a CCC-2 system.

An NE5000E cluster can be rolled back to an NE5000E single chassis.
Carrier-class Reliability and Manageability
NE5000E series routers offer carrier-class reliability and manageability. An NE5000E series
router can be installed in an N68E cabinet or a standard 19-inch cabinet.
NE5000E series routers also provide a powerful monitoring system. The main processing
units (MPUs) manage, monitor, and maintain the boards, fan modules, and power modules of
the entire system.
NE5000E series routers comply with Electromagnetic Compatibility (EMC) standards. The
modular design of the NE5000E series routers achieves EMC isolation between boards.

Support multi-service networks.
Different services are deployed on different VSs, forming a logical multi-service network.
This isolates different types of services to improve security and reliability.

Verify new services.
New services, such as IPv6 and video services, can be verified on VSs, which isolate
services and have no impact on the existing network applications.
Ideal L2VPN Solution
NE5000E series routers support the MPLS L2VPN technology. MPLS L2VPN transparently
transmits Layer 2 user data over an MPLS network. From a user's perspective, an MPLS
network is a Layer 2 switching network on which Layer 2 connections can be set up between
nodes. MPLS L2VPN can be classified as virtual private LAN service (VPLS) or virtual
private wire service (VPWS).
VPWS is a technology that transmits Layer 2 services by emulating basic behaviors and
features of services such as Ethernet, synchronous optical network (SONET), and
synchronous digital hierarchy (SDH) on a packet switched network (PSN). VPWS is a
point-to-point L2VPN technology. A VPWS service enables two sites to communicate as if
they were directly connected by a link. A VPWS service, however, cannot allow more than
two sites to communicate.
VPLS uses the PSN to connect multiple Ethernet LAN segments, enabling them to work as a
single LAN. VPLS is also called transparent LAN service (TLS) or virtual private switched
network service (VPSNS). Different from common point-to-point L2VPN services, VPLS
enables a service provider to offer an Ethernet-based multipoint service to users over an
MPLS backbone network.
Easy Rollback Configuration
NE5000E series routers provide the rollback function. Rollback is important for configuration
management as it can reduce the operation error ratio and improve device maintenance
efficiency.

Physical Architecture of an NE5000E CCC-A
An NE5000E CCC-A consists of the following systems:

Power distribution system
Power modules work in N+N backup mode. Together with the power backplane and the
system backplane, the power modules supply power for boards and provide independent
-48 V power for fan modules.

Heat dissipation system
The upper and lower parts of the chassis each has two fan frames to dissipate heat for
boards.

NMS

Functional host system
The functional host system consists of a system backplane, MPUs, optical flexible cards
(OFCs), SFUs, and internal communication units (ICUs).
The functional host system manages and controls the other systems, and provides control and
data channels. Figure 2-2 shows the functional host system of an NE5000E CCC-A.

Physical Architecture of a CCC-0 System
A CCC-0 system is the simplest NE5000E cluster. In a CCC-0 system, two CLCs (a master
chassis and a slave chassis) are connected, as shown in Figure 2-4.

Figure 2-4 Physical architecture of a CCC-0 system
The CCC-0 system uses the concepts of master and slave chassis:

The chassis in master mode is called a master chassis. The master chassis manages all
components of the entire system. All components, including boards, power modules, fan
modules, and the liquid crystal display (LCD), must be registered with the master MPU
in the master chassis.

The chassis in slave mode is called a slave chassis. The functions of the MPUs in the
slave chassis are simplified. Aside from providing control channels, the MPUs in the
slave chassis provide only diagnostic and debugging functions, but do not support
routing protocols, MPLS, QoS, or multicast functions.
The physical architecture of a CCC-0 system is similar to that of a CLC, and also includes the
following systems:

Power distribution system

Heat dissipation system

Network management sub-system

Functional host system
The power distribution system, heat dissipation system, and network management sub-system
of a CCC-0 system are the same as those of a CLC. The functional host system of a CCC-0
system, however, differs from that of a CLC and consists of two parts:


dissipation systems of both the master and slave chassis. The functional host system of
the master chassis uses a network management interface to connect to the NMS.

Functional host system of the slave chassis: manages the slave chassis.
Physical Architecture of a CCC-1 System
A CCC-1 system consists of one CCC and a maximum of four CLCs, as shown in Figure 2-5
and Figure 2-6.
Figure 2-5 Physical architecture of a CCC-1 system (NE5000E cluster)
Figure 2-6 Physical architecture of a CCC-1 system (400G cluster)
A CCC-1 system uses stage-1, stage-2, and stage-3 switch fabrics. In a CCC-1 system, a CLC
provides LPUs and stage-1 and stage-3 switch fabrics; a CCC provides a routing engine and a
stage-2 switch fabric.

The functions of these planes are as follows:

The data plane is responsible for high-speed processing and congestion-free switching of
data packets. It encapsulates and decapsulates packets, forwards IPv4/IPv6/MPLS
packets, performs QoS and queue scheduling, switches data at a high speed, and collects
statistics.

The control and management plane is the core of the entire system. It controls and
manages the system. The control and management plane processes protocols and
signaling, configures and maintains the system status, and reports and controls the
system status.

The monitoring plane independently monitors the ambient environment of the system. It
detects voltages and temperatures, and controls fan modules and power-on and power-off
of the system, thereby ensuring system security and stability. In addition, if a unit

becomes faulty, the monitoring plane can isolate the fault immediately so that it does not
affect the proper operation of the other units.
Logical Architectures of CCC-1 and CCC-2 Systems
CCC-1 and CCC-2
The logical architectures of CCC-1 and CCC-2 systems consist of the following logical
functional modules:

Routing control module

Management control module

Monitoring plane

Switch fabric

Forwarding plane
The implementation of modules in a CCC-1 or CCC-2 system, however, is different to that of
a CLC. A CCC-1 or CCC-2 system consists of two parts: CCC (NE5000E CCC or
NE5000E CCC-A) and CLC. A CLC can be an NE5000E-16 or NE5000E-X16 or
NE5000E-X16A that supports the cluster cascading function.
A CLC consists of the following functional modules:

Monitoring plane

Management control module

Forwarding plane

Switch fabric (S1 and S3)
A CCC consists of the following functional modules:

Monitoring plane

Management control module

Switch fabric (S2)

Routing control module
Figure 2-11 shows the distribution of functional modules in a CCC and a CLC. The CCC and
CLC exchange data through control and data channels.

6 Security Features
Whitelist
A whitelist contains a set of valid users or users with high priorities. By configuring the
whitelist, you can enable the NE5000E to protect existing services or user services with
high priorities.

Blacklist
A blacklist contains a set of unauthorized users. A blacklist can be self-defined based on
ACL rules, and is used to filter packets.

User-defined flow

Active link protection
The NE5000E uses the whitelist to protect TCP-based application-layer sessions.

Centralized configuration of CAR parameters
The NE5000E allows you to:

−
Configure CAR parameters for different LPUs in a centralized manner.
−
Use a uniform configuration interface to configure CAR parameters.
−
Configure protocol-specific CAR parameters.
Smallest packet compensation
The NE5000E can efficiently defend against attacks from small packets using the
smallest packet compensation function. After receiving a packet to be sent to the CPU,
the NE5000E checks the packet length:
−
If the packet is shorter than the preset minimum packet length, the router calculates
the rate at which packets are sent based on the preset minimum length.
−
If the packet is longer than the preset minimum packet length, the router calculates
the rate at which packets are sent based on the actual packet length.
BGP Flowspec
BGP Flowspec enables the NE5000E to:

Filter BGP traffic based on the ACL policy carried in BGP packets.

Filter BGP traffic based on the route attribute carried in BGP packets.

Redirect traffic to a specified TE tunnel.

Redirect traffic to a specified next hop.
Local Mirroring
The mirroring function, conforming to international standards, may be used to analyze the
communication information of terminal customers for a maintenance purpose. Before enabling the
mirroring function, ensure that it is performed within the boundaries permitted by applicable laws and
regulations. Effective measures must be taken to ensure that information is securely protected.
In local mirroring, an LPU can be configured with a physical observing interface, multiple
logical observing interfaces, and multiple mirrored interfaces.
The NE5000E supports inter-board local mirroring. The observing and mirrored interfaces can
be configured on different boards.
The NE5000E supports upstream mirroring. All packets or packets that match specific rules
received by a mirrored interface are copied to a specified observing interface.

Product Description
6 Security Features
The proportion of mirrored packets can be configured. For example, you can mirror only 10%
of a 100 Gbit/s traffic flow.
NetStream
The NetStream function conforms to IETF RFC3954. For security risks, see IETF RFC3954. This
function involves analyzing the communications information of terminal customers. Before enabling the
function, ensure that it is performed within the boundaries permitted by applicable laws and regulations.
Effective measures must be taken to ensure that information is securely protected.
NetStream provides the following functions:

Accounting

Network planning and analysis

Network monitoring

Application monitoring and analysis

Detection of unusual traffic
The implementation of NetStream requires three devices: NetStream data exporter (NDE),
NetStream collector (NSC), and NetStream data analyzer (NDA).
The NE5000E can function as NDEs to sample packets, aggregate flows, and output flows.
Based on the location of packet sampling and flow processing, NetStream is classified into:

Distributed NetStream: An LPU can sample packets, aggregate flows, and output flows
independently. Distributed NetStream supports load balancing among multiple
NetStream boards.

Integrated NetStream: Some LPUs do not support flow processing. They can only
sample packets and send the sampled packets to the LPUF-100, LPUI-100 for flow
aggregation and flow output. NetStream on these LPUs is called integrated NetStream.
The LPUF-100, LPUI-100 sample packets, aggregate flows, and output flows locally.
The NE5000E supports the following sampling functions:

Packet sampling on inbound and outbound interfaces (some boards support packet
sampling on inbound interface only)

Interface-based sampling and traffic-classifier-based sampling

Sampling of IPv4 unicast/multicast packets, fragmented packets, MPLS packets, MPLS
L3VPN packets, and IPv6 packets

Fixed packet sampling, random packet sampling, fixed interval sampling, and random
interval sampling

Sampling on various physical and logical interfaces, such as POS interfaces, Ethernet
interfaces, and trunk interfaces.
The NE5000E supports the following flow aggregation and output functions:

IPv4 packets can be aggregated based on options such as as, as-tos, protocol-port,
protocol-port-tos, source-prefix, source-prefix-tos, destination-prefix,
destination-prefix-tos, prefix, and prefix-tos.

MPLS packets can be aggregated based on Layer 3 labels.

Collected statistics can be output in V5, V8, or V9 format. The 16-bit and 32-bit AS
numbers are supported, and can be configured using commands. If the packets are output
in the V9 format, both the 16-bit and 32-bit NetStream interface indexes are supported,
which can be set using commands as required.

RFC 7013, and RFC 7015 standards. For details about security risks, see relevant descriptions in these
standards. This function can be used to analyze communication contents of specific target users for
maintenance and operation purposes. Strictly observe the local law when using this function. When
collecting and storing communication contents of specific users, ensure that the contents are profoundly
protected.
IPFix provides the following functions:

Accounting

Network planning and analysis

Network monitoring

protocol-port-tos, source-prefix, source-prefix-tos, destination-prefix,
destination-prefix-tos, prefix, and prefix-tos.

IPv6 packets can be aggregated based on options such as as, as-tos, protocol-port,
protocol-port-tos, source-prefix, source-prefix-tos, destination-prefix,
destination-prefix-tos, prefix, and prefix-tos.

MPLS packets can be aggregated based on Layer 3 labels.

Each type of aggregated flow can be output to eight network management servers.
Online Packet Header Capture
Based on your requirements to detect failures in telecom transmission, this feature may collect
or store some communication information about specific customers. Huawei cannot offer
services to collect or store this information unilaterally. Before enabling the function, ensure
that it is performed within the boundaries permitted by applicable laws and regulations.
Effective measures must be taken to ensure that information is securely protected.
Online packet header capture is similar to the mirroring function. Packets are processed using
the mirroring process. Then replicated packets are sent to a CPU of an MPU and stored in the
CPU memory and CF card.
Online packet header capture provides the following functions:

HUAWEI NE5000E Core Router
Product Description
7 Service Features
7.4 MPLS Features
The NE5000E supports MPLS and dynamic label switched paths (LSPs). Dynamic LSPs are
established dynamically by the Label Distribution Protocol (LDP) or Resource Reservation
Protocol (RSVP)-TE based on routing information.
Basic Features
The NE5000E supports the following MPLS functions:

Basic MPLS functions, service forwarding, and LDP (MPLS signaling distributes labels,
sets up LSPs, and transfers parameters used for LSP establishment)

LDP supports:
−
Label distribution in DU mode
−
Label control in independent or ordered mode
−
Liberal label retention mode
−
Loop detection using the maximum number of hops or path vector

MPLS ping and tracert, and LSP availability check using MPLS Echo Request and
MPLS Echo Reply packets

MPLS QoS, mapping of the ToS field in IP packets to the EXP field in MPLS packets,
and MPLS uniform, pipe, and short pipe modes

MPLS trap

LDP GTSM

P2MP

Remote LFA
The NE5000E can serve as label edge routers (LERs) or label switching routers (LSRs):

An LER is an edge device on the MPLS network. It classifies services, distributes labels,
and adds or removes labels.

An LSR is a core router on the MPLS network. It switches and distributes labels.
MPLS TE
The MPLS TE technology integrates the MPLS technology with traffic engineering. It can
reserve resources by setting up LSPs for a specified path in an attempt to avoid network
congestion and balance network traffic.
If resources are scarce, MPLS TE can preempt the bandwidth resources of LSPs with low
priorities. This meets the demands of LSPs with large bandwidth or LSPs carrying important
services. In addition, when an LSP fails or a node is congested, MPLS TE can protect network
communication using the backup path and FRR.
MPLS TE provides the function to process various types of constrained route-label switched
paths (CR-LSPs).
CR-LSPs are classified into the following types:

RSVP-TE

Auto route
The auto route mechanism works in either of the following modes:

7 Service Features
−
IGP shortcut: A device uses a TE tunnel for local route calculation and does not
advertise the TE tunnel to its peers as a route. Therefore, the peers of this device
cannot use the TE tunnel for route calculation.
−
Forwarding adjacency: A device uses a TE tunnel for local route calculation and
advertises the TE tunnel to its peers as a route. Therefore, the peers of this device
can use the TE tunnel for route calculation.
FRR
TE FRR switching can be completed within 50 ms, minimizing data loss caused by
network failures.

Auto FRR
Auto FRR is an extension of MPLS TE FRR. Auto FRR allows you to set up a bypass
tunnel for a primary tunnel. If the primary tunnel changes, the old bypass tunnel will be
automatically deleted and a new bypass tunnel will be set up.

CR-LSP backup
The NE5000E supports the following backup modes:

−
Hot backup: A backup CR-LSP is set up immediately after a primary CR-LSP has
been set up. If the primary CR-LSP fails, MPLS TE switches traffic to the backup
CR-LSP immediately.
−
Common backup: A backup CR-LSP is set up when the primary CR-LSP fails.
LDP over TE
On existing networks, not all devices support MPLS TE. Maybe only the core devices
support TE whereas the edge devices use LDP. In this case, LDP over TE can be
introduced. LDP over TE indicates that a TE tunnel is considered as a hop of the entire
LDP LSP.
SR-TE
The NE5000E supports the following segment routing (SR)-TE functions:

Strict label stack

Stitching label

L2VPN, L3VPN, and LDP over SR-TE

Hot standby (HSB) LSP, and Bidirectional Forwarding Detection (BFD) for SR-TE LSP

Class-based tunnel selection (CBTS)
7.5 VPN Features
7.5.1 Tunnel Policy
Tunnel policies are used to select tunnels based on destination IP addresses. Applications that
require tunnels select suitable tunnels based on tunnel policies. If no tunnel policy is
configured, the tunnel management module selects tunnels based on the default policy.
NE5000E support the following tunnel policies:

Tunnel type prioritizing policy
In a tunnel type prioritizing policy, you can specify the sequence in which tunnels are
selected, and the number of tunnels for load balancing. Among all tunnels to the same

destination, the tunnels with the highest priority will be selected as long as they are Up,
regardless of whether they have been selected by other services. The tunnels with lower
priorities will not be selected unless load balancing is required or the tunnels with higher
priorities are Down.

Tunnel binding policy
In a tunnel binding policy, you can bind a VPN to a specific MPLS TE tunnel, so that
traffic from the VPN is exclusively transmitted over the specified MPLS TE tunnel.
Tunnel binding policies can be used to ensure QoS for specified VPN services.
7.5.2 VPN Tunnel
NE5000E support the following types of VPN tunnels:

LSPs

TE tunnels
7.5.3 BGP/MPLS L3VPN


Inter-AS VPN
NE5000E support the following BGP/MPLS L3VPN features:

−
VPN Instance to VPN Instance: The sub-interface between autonomous system
boundary routers (ASBRs) manages VPN routes. This solution is also called
Inter-Provider Backbones Option A.
−
EBGP redistribution of labeled VPN-IPv4 routes: ASBRs advertise labeled VPNv4
routes to each other through Multiprotocol External Border Gateway Protocol
(MP-EBGP). This solution is also called Inter-Provider Backbones Option B.
−
Multi-hop EBGP redistribution of labeled VPN-IPv4 routes: PEs advertise labeled
VPN-IPv4 routes to each other through Multihop MP-EBGP. This solution is in
compliance with RFC 3107 and is also called Inter-Provider Backbones Option C.

The NE5000E uses MPLS L2VPN to transparently transmit Layer 2 user traffic over MPLS
networks. From a user's perspective, an MPLS network is a Layer 2 switching network on
which Layer 2 connections can be set up between nodes.
MPLS L2VPN supports the following networking modes:

Pseudo wire emulation edge-to-edge (PWE3)

VPLS

Kompella VLL

Kompella VPLS
7.6 QoS Features
NE5000E provide QoS functions.
QPPB
On NE5000E, QoS Policy Propagation Through the Border Gateway Protocol (QPPB)
classifies packets and defines QoS policies based on the community attribute, IP-prefix,
AS_Path, or ACL. This reduces the need to modify configurations when there are changes in
network structure.
DiffServ Model
Multiple service flows can be aggregated into a behavior aggregate (BA), and forwarded
based on the same per-hop behavior (PHB), thereby simplifying service processing and
storage.
On the DiffServ core network, QoS is packet-specific, and therefore signaling is not required
for packet processing.
BA Classification
At present, NE5000E support BA classification on physical interfaces and their sub-interfaces,
and logical interfaces such as trunk interfaces.
Eight DiffServ domains are supported. PHB on outbound interfaces can be disabled. Eight
service queues are reserved on each interface.
BA classification can be based on:

8021p mapping

DSCP mapping

EXP mapping
MF Classification
Multi-field (MF) classification can be based on:


IPv4 rules: source IP address, destination IP address, IP protocol number, IP
fragmentation flag, DSCP, ToS + precedence, time-range, TCP/UDP source port number,
and TCP/UDP destination port number

Layer 2 rules: source MAC address, destination MAC address, 802.1p, or Etype

IPv6 rules: source IP address, destination IP address, IP protocol number, DSCP, ToS +
precedence, next header, TCP/UDP source port number, and TCP/UDP destination port
number

MPLS rule: EXP
NE5000E also support MF classification on logical interfaces, such as sub-interfaces and
trunk interfaces.
Traffic Policing
CAR is used to limit the traffic rate. CAR uses a token bucket to measure the traffic that pass
through an interface. Only the packets assigned with tokens can pass through the interface
within the specified time period. In this manner, the traffic rate is limited. CAR can limit the
rates of both incoming and outgoing traffic. In addition, CAR can control the rates of certain
types of traffic according to information such as the IP address, port number, and priority. The
traffic not meeting specified conditions is forwarded at the original rate.
CAR is mainly applied to network edge devices to ensure that core devices can process data
properly. NE5000E support CAR for both incoming and outgoing traffic.
Queue Scheduling
NE5000E can use first in first out (FIFO), PQ, and WFQ to schedule queues on interfaces.
Traffic Shaping
If network congestion occurs, traffic policing that uses the CAR technology can restrict traffic
by dropping packets that do not match specified rules. To prevent too many packets from
being dropped, the excess packets can be buffered and then sent out evenly under the control
of token buckets. This is called traffic shaping. Traffic shaping prevents too many packets
from being dropped and helps packets to match specified rules.
Traffic shaping is mainly used to control the volume of burst outgoing traffic over a certain
link so that the packets can be transmitted at an even rate. Generic traffic shaping (GTS) is a
technology used in traffic shaping. By shaping traffic that does not match specified rules, GTS
allows the matching between the upstream and downstream bandwidths.
Ethernet QoS
NE5000E support BA classification based on the 802.1p priority in VLAN packets. On the
ingress PE, the 802.1p priority in a Layer 2 packet is mapped to the precedence in an
upper-layer protocol packet, such as the IP DSCP value or the MPLS EXP value, thereby
providing the DiffServ service for the packets on the backbone network. On the egress PE, the
precedence of the upper-layer protocol packet is mapped to the 802.1p priority.
Enhanced ACL
Detailed information about packets can be viewed if they are matched based on ACLs.

7 Service Features
7.7 Traffic Load Balancing
If there are multiple routes to the same destination, traffic can be load balanced among these
routes. You can select either equal-cost load balancing or unequal-cost load balancing based
on customer or network requirements.
Equal-Cost Load Balancing
NE5000E support equal-cost load balancing among IP-Trunk or Eth-Trunk member links. If
there are multiple equal-cost routes to the same destination, NE5000E support equal-cost load
balancing of traffic among these routes.
There are two types of equal-cost load balancing: session-by-session and packet-by-packet.
By default, session-by-session load balancing is used.
Unequal-Cost Load Balancing
NE5000E support the following unequal-cost load balancing modes:

Route-based load balancing: When the costs of different direct routes are the same, you
can configure the weight of each route for load balancing.

Interface-based load balancing: On an IP-Trunk or Eth-Trunk, you can configure the
weight of each member link for load balancing.

Link-bandwidth-based load balancing: Unequal-cost load balancing is performed on the
outbound interfaces of links based on link bandwidth. Traffic is shared between links
based on the bandwidth of each link. That is, less traffic is forwarded over
lower-bandwidth links, and more traffic is forwarded over higher-bandwidth links. This
prevents lower-bandwidth links from being congested and higher-bandwidth links from
being idle.
NE5000E support traffic load balancing among physical interfaces or among physical and
logical interfaces. In addition, the system can detect the changes of bandwidth on logical
interfaces caused by manual configuration or the status changes (Up/Down) of member links.
If the bandwidth of a logical interface changes, traffic will be rebalanced automatically.
7.8 Traffic Statistics Collection
The NE5000E provides various types of traffic statistics collection for different access users.
Traffic statistics collection helps carriers analyze the network traffic model, provides
reference data for deploying and maintaining DiffServ TE, and supports volume-based
accounting of non-monthly flat fee subscribers.
Traffic Statistics Collection Based on QoS Policies
The NE5000E supports traffic statistics collection based on QoS policies on interfaces,
including Ethernet interfaces and their sub-interfaces, POS interfaces, Eth-Trunk interfaces
and their sub-interfaces, and IP-Trunk interfaces.
CAR Traffic Statistics Collection
The NE5000E provides QoS features such as traffic classification, traffic policing CAR, and
queue scheduling. Accordingly, QoS traffic statistics collection is provided:


In traffic classification, statistics on traffic that matches or does not match rules are
collected.

In traffic policing, traffic statistics collection is supported as follows:
−
Statistics on total traffic that matches the CAR rule are collected.
−
Statistics on traffic that is permitted or dropped based on the CAR rule are
collected.
−
Traffic statistics collection based on traffic policies is supported on interfaces.
−
If the same traffic policy is applied to different interfaces, the CAR traffic statistics
in the traffic policy are interface-specific.
Interface-based Traffic Statistics Collection
The NE5000E supports traffic statistics collection on interfaces and sub-interfaces.
Traffic Statistics Collection on TE Tunnels
When functioning as a PE on an MPLS TE network, the NE5000E can collect statistics on the
incoming and outgoing traffic in tunnels.
Traffic Statistics Collection on LDP LSPs
When functioning as a P or PE on an MPLS TE network, the NE5000E can collect traffic
statistics on LDP LSPs.
7.9 Network Reliability
Backup of Key Parts
An NE5000E can be equipped with a single MPU or dual MPUs (in backup mode). If two
MPUs are equipped, the two MPUs work in hot backup mode. The management network
interface on the slave MPU cannot be accessed by users, and the console interfaces cannot be
configured with any command. The slave MPU exchanges information (including heartbeat
messages and backup data) only with the master MPU.
The system supports two types of master/slave MPU switching: failover and switchover. A
failover is triggered either by a master MPU reset or by a serious master MPU fault. A
switchover is triggered by commands run on the console interface. You can also run
commands on the console interface to disable master/slave MPU switching.
NE5000E support backup of management buses and backup of power modules. In addition,
the LPUs, power modules, and fan modules are hot swappable.
If a critical fault occurs on an NE5000E, the router quickly takes responsive measures. As a
result, the mean time between failures (MTBF) is prolonged, and the impact of faults on
normal services is minimized.
High Reliability of LPUs
NE5000E support protocol backup on service interfaces of the same type. For example:

Issue 01 (2016-06-30)
Member interfaces of an Eth-Trunk or IP-Trunk can be backed up inside a group.

Inter-board trunk bundling can be achieved:
−
Users can use dual links to connect to different LPUs. Inter-board trunk bundling
ensures high reliability of services.
−
Inter-board trunk bundling is achieved by means of high-performance hardware
engines, allowing traffic to be load-balanced among multiple links.
−
The hash algorithm balances the traffic on each link based on source and destination
IP addresses.
−
A seamless switchover is implemented in the case of a link failure, so that services
are still forwarded normally.
Transmission Alarm Customization and Suppression
Transmission alarm suppression can efficiently filter and suppress alarms, preventing
interfaces from frequently flapping. In addition, transmission alarm customization is provided
for you to control the impact of alarms on interface status by specifying which alarms can
cause interface status changes.
BFD
BFD is a detection mechanism used to monitor and rapidly detect the connectivity of
network-wide links or IP routes.
BFD sends detection packets at the same time from both ends of a bidirectional link to check
the link status in both directions. BFD can detect link faults within milliseconds. NE5000E
support both single-hop and multi-hop BFD.
NE5000E support:

Distributed BFD: Some LPUs can set up BFD sessions independent of other LPUs.

Integrated BFD: Some LPUs do not support BFD and must depend on the LPUF-100 and
LPUF-200 to set up BFD sessions. All the state machines of BFD sessions are
established on the LPUF-100 and LPUF-200.
The NE5000E support the following BFD applications:

BFD for Virtual Router Redundancy Protocol (VRRP)

BFD for FRR, including BFD for LDP FRR, BFD for IP FRR, and BFD for VPN FRR

BFD for static route

BFD for IS-IS
On an NE5000E, the statically configured BFD session can be used to detect an IS-IS
neighbor relationship.
BFD detects faults on the links between IS-IS neighbors and rapidly reports the faults to
IS-IS, thereby triggering fast convergence of IS-IS routes.

BFD for IPv6 IS-IS
On an NE5000E, IPv6 IS-IS can dynamically create and delete BFD sessions.

BFD for OSPF/BGP
On an NE5000E, OSPF and BGP can dynamically create and delete BFD sessions.

BFD for OSPFv3/BGP4+
On an NE5000E, OSPFv3 and BGP4+ can dynamically create and delete BFD sessions.

BFD for IP-Trunk and Eth-Trunk
On an NE5000E, BFD can detect a trunk and the member links of the trunk separately. In
other words, BFD can detect the connectivity of a trunk and also the connectivity of
important member links of the trunk.

BFD for LSP
BFD for LSP rapidly detects and reports faults on LSPs, TE tunnels, and PWs so that
MPLS services, such as VPN FRR and TE FRR, can be rapidly implemented.

BFD for P2MP (supported by LPUF-400s and LPUI-480s )
Ethernet OAM
NE5000E support Ethernet operation, administration and maintenance (OAM), which consists
of:

EFM OAM (Ethernet in the First Mile OAM)
−

NE5000E comply with 802.3ah to provide point-to-point fault management for
Ethernet links so that the faults on the first-mile direct Ethernet link at the user end
can be detected. Currently, NE5000E support automatic ND, link fault monitoring,
remote fault notification, and remote loopback configuration.
CFM OAM (Connectivity Fault Management)
−
Provides hierarchical MD and end-to-end fault management for Ethernet links.
VRRP
A VRRP backup group that consists of a group of routers on a LAN functions as a virtual
router. Hosts on the LAN only know the IP address of this virtual router and do not know the
IP address of any specific routers in the VRRP backup group. The hosts set their own default
next hop address to the IP address of the virtual router. This allows hosts on the LAN to
communicate with hosts on other networks through the virtual router.
VRRP dynamically associates the virtual router with a physical router that transmits services.
When the physical router fails, another router is selected to transmit services. The switchover
of services from the faulty router to the new router is transparent to users, which allows
non-stop communication between hosts on different networks.
FRR
NE5000E provide the following FRR features to improve reliability:

IP FRR
FRR can be completed within 50 ms, minimizing data loss caused by network failures.
FRR monitors and records the LPU and interface status in real time, and checks the
interface status in packet forwarding. When faults occur on an interface, the traffic on the
interface can be rapidly switched to another route. This prolongs the MTBF and reduces
the number of lost packets.

LDP FRR
LDP FRR can be completed within 50 ms, minimizing data loss caused by network
failures.

Product Description
7 Service Features
TE FRR is used in MPLS TE for local protection. It is supported only on interfaces
working at 100 Mbit/s. TE FRR can be completed within 50 ms, minimizing data loss
caused by network failures.
TE FRR is only a provisional protective measure. If a protected LSP recovers or a new
LSP is established, traffic will be switched back to the recovered LSP or the newly
established LSP.
After TE FRR is configured for an LSP, the traffic will be switched to the protection link
and the ingress of the LSP attempts to establish a new LSP if a link or a node becomes
faulty.
TE FRR can be classified into the following types based on different protected objects:

−
Link protection
−
Node protection
BGP auto FRR
BGP auto FRR is used to protect BGP routes. If the primary link fails, traffic can be
switched to the backup link within 200 ms. BGP auto FRR is used in the following
typical application scenarios:

−
Intra-AS FRR
−
Inter-AS FRR
−
PE-CE protection
VPN FRR
VPN FRR can be completed within 50 ms, minimizing data loss caused by network
failures.

This solution applies to new deployment, capacity expansion, and the construction of
large-scale ISP provincial backbone networks. These ISP networks have advantages in
transmission resources, access services, and operation and maintenance costs. If transmission
resources are insufficient, you can reduce link bandwidth without changing the network
topology. The devices on the core layer support line rate forwarding of packets. Devices on
the entire network support MPLS VPN.

Considering the status quo of the existing bearer network, carriers need to construct a set of
core bearer networks to carry 3G and next generation network (NGN) services. With the
development of new services and technologies in a competitive market, the new IP bearer
network will become a next-generation multi-service bearer platform that supports NGN,
video conference, video phone, streaming media, enterprise interconnection, and 3G services.
The construction of the new IP bearer network is key for network convergence and
transformation.
In this solution, NE5000E function as core nodes, which forward data at a high speed and
ensure high reliability. NE40Es function as aggregation routers, which provide access for
NGN voice, signaling, network management, and VIP services.
This solution has the following characteristics:

The core layer uses a dual-plane structure. NE5000E are fully meshed.

NE40Es are dual-homed to NE5000E.

Two devices working in backup mode are deployed at each important node.

MPLS VPN is deployed on the entire network to isolate different types of users and
services.

VPN FRR is deployed on each PE.

TE FRR and Interior Gateway Protocol (IGP) fast convergence are deployed on the
entire network.

Deploying the IPv6 backbone network solution does not affect the original IPv4 services,
such as IPv4 forwarding and MPLS VPN, and can meet the following requirements:

Interconnection between separate IPv6 networks

Interworking between IPv6 and IPv4 networks
The IPv6 backbone network solution can be implemented using either of the following
methods:

All routers on the backbone network support the IPv4/IPv6 dual stack. IPv4 services are
forwarded over IPv4, and IPv6 services are forwarded over IPv6.

The separate IPv6 networks can be interconnected over 6to4 or manually configured
Layer 3 tunnels. The core routers need to support only IPv4 forwarding and do not need
to be upgraded.

9.1 Operation and Maintenance
9.1.1 System Configuration Management
Configuration Mode
NE5000E support the following configuration modes:

Command line configuration
In this mode, you can log in to an NE5000E through the console interface or by means of
Telnet to perform configurations.

NMS configuration
In this mode, you can use the NMS to configure an NE5000E.

NE5000E support the configuration rollback function.
Intelligent Configuration
As new types of services emerge, there are higher requirements on devices. For example, it is
required that services take effect after being configured, invalid configurations be rolled back,
and the impact on existing services be minimized. NE5000E support the following
configuration features:

Offline Configuration
After a configuration file is generated using the offline configuration tool, the
configuration file can be saved. You can load the configuration file to an NE5000E after
it has restarted.
If an NE5000E is online but some boards or subcards on the router are offline, the offline
configuration tool can still be used.

If the activated configuration results in performance deterioration, running a related
command can roll the NE5000E back to the previous configuration. Compared with
deleting every single command, the configuration rollback function allows faster and
more convenient configuration restoration.

Configuration commitment prompt
After the configuration takes effect, the NE5000E adds it to the running database. If the
same configuration is added, the router generates a message.
9.1.2 System Management and Maintenance
NE5000E provide the following powerful system management and maintenance functions:

Board detection, hot swap detection, Watchdog, board resetting, RUN indicator and
debugging indicator control, fan and power supply control, master/slave switchover
control, and version query

Local and remote loading and upgrade of software and data, and configuration rollback,
backup, saving, and clearing

Hierarchical user authority management, operation log management, command line
online help, and command comments

Multi-user operation

Multi-layer information collection, including interface, Layer 2, and Layer 3 information

Hierarchical management, alarm classification, and alarm filtering
9.1.3 Device Operating Status Monitoring
An NE5000E uses the information center to monitor operating status.
Syslog is a sub-function of the information center. Syslog runs atop UDP. It outputs
information to a log host through port 514.
The information center can receive and process the following types of information:

Log information

Debugging information

Trap information
Information has eight severity levels. A lower level indicates higher severity.
Level
Severity
Description
0
Emergency
A fatal exception occurs on the device, which causes the
system to be unable to run properly unless the device is
restarted. For example, program exceptions or memory usage
errors are detected.
1
Alert
A serious exception occurs on the device, which requires
immediate actions. For example, the memory usage of the
device reaches the upper threshold.
2
Critical
A critical exception occurs on the device, which requires
immediate actions and cause analysis. For example, the
memory usage falls below the lower threshold, the
temperature falls below the alarm threshold, BFD detects that
a device is unreachable or error messages are generated by

the local device.
3
Error
A misoperation or abnormal process occurs on the device,
which does not affect subsequent services but requires
attention and cause analysis. For example, incorrect
commands or passwords are entered, or error protocol
packets received by other devices are detected.
4
Warning
An exception that may result in a fault occurs on the device,
which requires attention. For example, a routing process is
disabled, BFD detects packet loss, or error protocol packets
are detected.
5
Notice
A key operation is performed to keep the device running
properly. For example, the shutdown command is run on an
interface, neighbor discovery occurs, or the status of the
protocol state machine changes.
6
Informational
A routine operation is performed. For example, a display
command is run.
7
Debugging
A routine operation is performed, and no action is required.
The information center supports 10 channels, of which Channel 0 to Channel 5 have their
default channel names. By default, the six channels (Channel 0 to Channel 5) correspond to
six directions at which information is output. The log information on the Cfcard is output to a
log file through Channel 9 by default. That is, a total of seven default output directions are
supported.
When multiple log hosts are configured, you can configure log information to be output to
different log hosts through one or multiple channels. For example, you can configure some
log information to be output to a log host through Channel 2 (loghost), and some log
information to a log host through Channel 6. In addition, you can change the name of Channel
6. This facilitates the management of information channels.
9.1.4 System Service and Status Tracking
NE5000E support system service and status tracking. NE5000E can:

Monitor the changes of the state machines for routing protocols.

Monitor the changes of the LDP state machine.

Monitor the changes of the VPN state machine.

Monitor the protocol packets sent by the NP, and display detailed information about the
packets by enabling debugging.

Detect and collect statistics on abnormal packets.

Report a message when the exception handling process takes effect.

Collect statistics on the resources used by each feature.

9.1.5 System Test and Diagnosis
NE5000E provide a debugging function, which records key events, packet processing, packet
resolution, and status switch during service operation. The debugging function helps to debug
devices and networks. Debugging can be enabled or disabled using a console based on a
specified service (such as a routing protocol) and a specified interface (information about the
routing protocol on the specified interface).
Software detection and diagnosis supported on NE5000E provides a trace function, which
records key events, such as task switching, task interruptions, queue read and write, and
system exceptions. If an NE5000E is restarted after a fault occurs, the trace information can
be accessed and used for fault location. The trace function can be enabled or disabled by
running commands on the console.
NE5000E also allow you to query the CPU usage of MPUs and LPUs.
The debugging and trace information on NE5000E is classified into different levels and
output to different destinations, such as the console, Syslog server, or SNMP trap module,
based on these levels.
9.1.6 NQA
NE5000E provide NQA. NQA measures the performance of different protocols running on
the network. Carriers can collect network operation indicators in real time, such as the total
delay of Hypertext Transfer Protocol (HTTP), TCP connection delay, DNS resolution delay,
file transfer rate, FTP connection delay, and DNS resolution error rate. By monitoring these
indicators, carriers can provide users with network services of different levels, and charge
users accordingly. NQA is also an effective tool for diagnosing and locating network faults.
NE5000E provide the following NQA functions:

LSP ping, LSP traceroute, and MPLS jitter

NQA-MIB, which enables all NQA functions to be managed using the NMS
9.1.7 VS
With the increasing demand on network services and the diversified types of network services,
network management becomes more and more difficult, and the requirements for service
isolation, security, and reliability become greater.
In addition, with further development of the modular cluster and distributed routing and
switching systems, the service processing capability of a single physical system (PS) has
reached a new level.
The network administrator divides a PS into several VSs using hardware and software
simulation; each VS then performs routing tasks independently. Different VSs share software
and hardware resources except for interfaces. This means that different VSs can share the
same main control and interface boards, but each interface can belong to only one VS. A VS is
equivalent to an independent PS in terms of available functions.
With VS techniques, a single PS exerts strong service processing capabilities to simplify
networking and network management and enhance service security and reliability.
As an important feature of new-generation IP bearer devices, VS helps implement unified
operation of services for carriers and reduce the CAPEX and OPEX. A carrier divides a
large-sized PS into multiple separate and small VSs, improving capital allocation and
implementing horizontal or vertical network integration.

9.1.8 In-Service Debugging
NE5000E support interface mirroring, which maps specific traffic to a monitoring interface.
In addition, NE5000E support in-service debugging, which allows maintenance personnel to
debug and analyze network operating status.
9.1.9 Upgrade Features
In-service Upgrade
NE5000E support in-service software upgrade and in-service patching. By means of
in-service patching, you can upgrade only the features to be modified.
System Upgrade
The process of upgrading NE5000E is improved. The entire process can be completed with a
single command, saving time for you. The upgrade progress can be displayed, and you can
view the upgrade result after the upgrade is complete.
Rollback Function
During a system upgrade, if the new system software cannot start the system, the software in
the last successful startup can be used instead.
The rollback function provided by the NE5000E can prevent services from being affected by
system upgrade failures.
9.1.10 License
As software functions of NE5000E are increasingly diversified and software costs occupy a
larger proportion of the total costs, the service model currently provided can no longer meet
the following requirements of carriers:

Lower purchasing costs

Effective control over the capacities and functions of devices during system upgrades
and capacity expansion
To address different user requirements, NE5000E provide a license authorization management
platform called global trotter license (GTL). License authorization has the following
advantages:

Allows you to purchase only required service functional modules, reducing purchasing
costs.

Allows you to extend device functions and expand device capacities by purchasing new
licenses.
9.1.11 Other Features
NE5000E also support the following features:



You can enter a question mark (?) to obtain online help.

Rich and detailed debugging information can be provided to diagnose network faults.

The DosKey-like function can be configured so that a specific historical command can
be run.

The command resolver supports fuzzy match of keywords. For example, if the display
command needs to be resolved, you only need to input an exact matching string disp.
9.2 NMS
NE5000E support SNMP-based operation and management performed by the NMS.
NE5000E support the following SNMP versions:

SNMPv1
SNMPv1 supports community-name- or MIB-view-based access control.

SNMPv2c
SNMPv2c supports community-name- or MIB-view-based access control.

SNMPv3
SNMPv3 inherits the basic functions of SNMPv2c, defines a management frame, and
introduces a user-based security model (USM) to provide a more secure access control
mechanism for users.
SNMPv3 supports the following functions:
User group
Group-based access control
User-based access control
Authentication and encryption
NE5000E use Huawei iManager U2000. The U2000 is a unified NMS that covers multiple
domains to minimize operation and maintenance costs for customers and bring more network
benefits. The U2000 supports SNMPv1/v2c/v3 and the client/server model, runs
independently on many operating systems, such as Windows NT/2000/XP/2003 server/2007
server, UNIX (SUN, HP, and IBM), and provides a multi-lingual graphical user interface.
To be oriented toward future network development trends, the U2000 combines all-IP and
fixed mobile convergence (FMC) and manages bearer and access equipment in a centralized
manner. The U2000 can perform not only integrated management of multi-domain equipment
but also integrated management at the element and network management layers. The U2000
has revolutionized layer-based management to meet the requirements of the transition from
the existing vertical network to the flattened horizontal network.
