Rsmlt Peers Not Up; Enabling Trace Messages For Rsmlt Troubleshooting - Avaya 8800 Troubleshooting Manual

• Do not enable transmission of IPv6 ICMP Redirect messages on RSMLT VLANs (ICMP
redirect is disabled by default).
• No IPv6 connectivity is expected when the IST is down. Traffic recovery from an IST going
down takes multiple seconds.

RSMLT peers not up

If, after a series of reconfigurations, RSMLT peers do not transition to the up state, use the
following procedure to troubleshoot the issue. The issue may be observed on dual-stack
VLANs after multiple delete and re-adds of IPv4 interfaces, or disabling and reenable of IPv6
forwarding or similar configurations.
1. Display the RSMLT configuration
2. To recover the peers if they are down, disable and reenable RSMLT on both IST
3. If the problem persists, boot from a saved configuration.

Enabling trace messages for RSMLT troubleshooting

If the preceding information does not resolve the issue, you can use the following command
to obtain additional RSMLT-related information:
trace level 15 4 (CLI or ACLI)
Important:
Enabling this trace on a loaded system may slow down the CPU, especially if executed
through console. Use Telnet if possible.
Troubleshooting
show ip rsmlt info (CLI)
This command shows whether the peers are up.
peers:
config vlan <vid> ip rsmlt disable config vlan <vid> ip rsmlt
enable (CLI)
OR
no ip rsmlt ip rsmlt (ACLI from Interface Config mode)
