Physical Inspection before starting of the Preventive Maintenance 1. Check the Status of the LEDs on ARC cards (details of LED and expected results is available in Annexure ) 2. Check the Status of the LEDs on DSP cards (details of LED and expected results is available in Annexure ) 3. Check for the Status of the LEDs on NMC cards (details of LED and expected results is available in Annexure ) A.1 Observations/Output from RAS for ARC and DSP cards S.No. Observation 1. Use command Select a letter for one of the following options: ‘MONITOR RADIUS’ A) Monitor all RADIUS packets B) Monitor all RADIUS authentication packets C) Monitor all RADIUS accounting packets D) Monitor a specific user E) Monitor next session F) Monitor all packets to a specific server G) Monitor resource management packets X) Exit the monitor (i) Press ‘E’ (ii) Press ‘D’ Test Result Check for the authentication status of the next session It gives details of the Access-Request and Access—Accept or Access-Reject vis-àvis configured Radius. Similarly, one specific user access-request, access-accept/reject ( e.g. nib_test) may be seen. Page 6 of 20 Remark ( if any) 2. Use command Select a letter for one of the following options: C) Monitor PPP Call Events. ‘MONITOR PPP’ I) Monitor a specific interface. N) Monitor the next session that starts up. U) Monitor a specific user. T) Monitor a specific calling number. X) Exit the monitor. Please Enter Your Choice : (i) Press ‘U’ To see the authentication details for the specific users. ( e.g. One can see the session from one specific user like ‘nib_test’ then enter this in the user_name field and connect with ‘nib_test’ and see the result (ii) Press ‘N’ Check for the Next session from any user that starts up. that starts up 3. Show all interface This command shows the setting active configuration for all active interfaces. 4. Show all interfaces 5. list ip pools This commands display all configured IP networks To see the details of the configured IP Pools on the ARC cards The ‘state’ should be ‘public’.’ Page 7 of 20 6. list interfaces This command line on the ARC shows Operation status and Admin Status of Modems on ARC Operation status indicates the ARC has the communication with the modem cards. Administrative Status indicates the userdefined status of the interface. In order to calls, the status of the both should be UP. (i) 7. Sh version 8. Sh cpu utilization 9. sh system 10. show board crashdump 11. Show statistics If there is Operation Status is down for any interface then there is a packet bus problem. Check to see if the card is there in the slot and that its RUN/FAIL light is green. (ii) If the Admin Status is down for any interface then the modem is not enabled. Displays the ARC software version This command displays an estimate of the router card’s CPU usage over various intervals. It shows the Software version and other details like (i) System Descriptor (ii) Object ID (iii) System Up time (iv) System name (v) System location (vi) System Version etc. It is a diagnostic tool for displaying information about a previous system crash stored in EEPROM This is useful for debugging purposes only This set of commands display statistical call and modem information. Call_disconnect_eason Call_duration Call_statistics Call_per_hour Modem_utilization Page 8 of 20 12 sh board Setting It shows the Hardware information of the ARC Card 13 sh memory It shows the ARC memory status. 14 list dns servers This command displays the information of the DNS servers already configured. 15 Show Statistics This commands gives the summary detail of Summary of Successful calls and call_statistics Unsuccessful calls Following Cards with Serial Nos. tested and found OK. The output of various commands attached */seen. 1. 2. 3. 4. 5. • In view of network security the output of various commands shall not be handed over to M/s ITI engineer, however the output must be checked at the node itself by the M/s ITI engineer for any problem. Page 9 of 20 B. Observations/Output from RAS for ARC and DSP cards after completion of Preventive Maintenance 1. Check for the Authentication and browsing for all the Services Configured on the Equipment ( e.g. Netone ). 2. Ping for the any site like ‘www.yahoo.com’ 3. Use command traceroute ‘Radius Server’ (Here Radius IP will be used for the Radius server marked for the location.
