ONcore Cannot PING the ARP Servers and Vice-versa
Use the SHOW DEVICE command and look at the Q2931 cause:
Cause Code: 31
Explanation: The IP address of the hub 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 ONcore hub.
Cause Code: 1
Explanation: A wrong ARP server address was entered with the SET DEVICE
ARP_SERVER command, or the port of the ARP server is NOT IN SERVICE or NO
ACTIVITY status.
Steps to Take:
1. Check that the port attached to the ARP server is OKAY, then check that the ATM
address shown by the ARP server is exactly the same as the one entered in the
ONcore hub (by entering the SHOW DEVICE command).
Cause Code: 3
Steps to Take: If the ARP server is in the same cluster (SSI links):
1. An SSI port has not enough bandwidth. Having several SSI ports on the module
may reach the bandwidth limit.
Spread the SSI ports over several modules.
2. The ATM address of an ONcore hub located on the PING path has been changed.
Disable the SSI link and re-enable it.
If the above does not solve the problem, take a TRS dump (with the DUMP TRS
command), and contact your 3Com representative.
