3.Troubleshooting Functional Failures in Operation

(2) Checking interface status

It is also possible that a failure has occurred on the hardware of the neighboring system connected to this system even if the hardware on this system is running properly.

The procedure for checking the status of interface between this system and the neighboring system is described below.

1.Log in to the system.

2.Check the Up/Down status of the interface between the systems using the show ip interface command.

3.When the interface is not displayed as VRF interface, see "(9)Checking option license OP-NPAR[OP-NPAR]."

[OP-NPAR]

4.If the interface is in the "Down" status, see "3.4 Network Interface Communication Failure."

5.If the interface is in the "Up" status, go to "(3)Identifying the extent of the failure (performed from this system)"

(3) Identifying the extent of the failure (performed from this system)

If no failure is found on this system, a failure may exist somewhere in the route between this system and the remote system. The procedure to locate the failure in the route to the remote system and identify the failure range is as follows:

1.Log in to the system.

2.Use the ping command to check communication between both parties. For an example of issuing ping and how to interpret the result, see the manual "Configuration Settings."

3.If communication to the other party cannot be verified with the ping command, use the ping command to check communication to remote systems starting from the system closest to this system.

4.If the result of the ping command shows that the neighboring system has failed, go to "(5)Checking ARP resolution information with neighboring system." If the result shows that the remote system has failed, go to "(6)Checking unicast routing information."

(4) Identifying the extent of failure (performed from the customer's terminal equipment)

If login to this system is not possible, follow the procedure below to identify the extent of failure to see the failure location in the route between the customer's terminal equipment and the other party.

1.Confirm that the customer's terminal equipment has the ping function.

2.Use the ping function to check communication between the customer's terminal equipment and the remote system.

3.If communication to the remote system cannot be verified with the ping command, use ping again to check communication to systems starting from the system closest to the customer's terminal equipment.

4.After the extent of failure has been identified using the ping command, log in to this system if it is considered to have failed and follow the failure analysis flow to check for the failure cause.

(5) Checking ARP resolution information with neighboring system

If communication to a neighboring system is not possible as a result of the ping command execution, address resolution by ARP may not have been achieved. The procedure for checking the status of address resolution between this system and the neighboring system is described below.

1.Log in to the system.

2.Use the show ip arp command to check the status of address resolution status with the neighboring system (presence/ absence of ARP entry information).

3.If the address resolution with the neighboring system is achieved (ARP entry information is provided), go to "(6)Checking unicast routing information."

4.Confirm that the IP network setting on the neighboring system matches that of this system if the address resolution with the neighboring system is not achieved (ARP entry information is not provided).
