8265 Cannot PING the ARP Servers and Vice-versa
Use the SHOW DEVICE command and look at the Q2931 cause code:
Cause Code: 31
Explanation: The IP address of the switch is not in the same IP subnet as the ARP server.
Steps to Take:
1. Change the IP address or IP subnet mask of the 8265.
Cause Code: 1
Explanation: A wrong ARP server address was entered with the SET DEVICE ARP_SERVER command, or the
status of the port of the ARP server is
DOWN: NOT IN SERVICE or DOWN: NO ACTIVITY .
Steps to Take:
1. Check that the status of the port attached to the ARP server is UP , then check that the ATM address shown by the
ARP server is exactly the same as the one entered in the 8265 (by entering the SHOW DEVICE command).
Cause Code: 3
Steps to Take: If the ARP server is in the same peer group (PNNI links):
1. A PNNI port has not enough bandwidth. Having several PNNI ports on the module may reach the bandwidth limit.
Spread the ports over several modules.
2. A connection has failed. Action to take varies according to the type of connection that has failed.
If you cannot solve the problem, take a PNNI dump (with the DUMP PNNI topology_data_base command), and
contact your IBM representative.
Cause Code: 3
Steps to Take: If the ARP-server is in another peer group (IISP links):
1. The IISP network-side/user-side definition rules have not been applied.
Check that one side of the link is defined as user, and that the other side is defined as network.
2. No VPC link has been defined for the port.
Define the link, using the SET VPC_LINK command.
3. The peer logical links do not match (bad vpi match, bad cluster match, bad bandwidth match).
Check that the logical links on both sides match, and if necessary, clear those logical links are re-define them.
4. No reachable address has been defined, if the 8265 and the ARP-server are in different ATM peer groups.
Define the reachable address using the SET REACHABLE_ADDRESS command.
5. A reachable address was badly configured.
Check the reachable addresses, using the SHOW REACHABLE_ADDRESS command.
6. The VP-tunnel is defective.
Ask your VP-tunnel provider to test it.
