Hi!
We have some troubles with igmp snooping when we are trying to change linecards from trident to typhoon. We have more then 1000 igmp groups on our router. Software version 5.3.4 SP7.
After changing linecards seems that IGMP messages starts to drop. End users can't subscribe to igmp groups and IGMP querier disappeared from access switches. After restarting process igmpsn I see IGMP group queries and multicast works 120 sec (2 query intervals) then stops again. No error messages in the routers log.
I tried to check this command: sh igmp trace error.
And I see this output:
Aug 5 03:06:58.683 igmp/error 0/RSP0/CPU0 t1 ERR:mpa_mgii_fetch_redist Failed: 'Subsystem(8191)' detected the 'unknown' condition 'Code(63)': Unknown Error(511)
Aug 5 03:08:37.054 igmp/error 0/RSP0/CPU0 t1 ERR:igmp_ipc_pulse_msg_handler: Handled 200 messages already. STOP!
Aug 5 03:08:37.063 igmp/error 0/RSP0/CPU0 t1 ERR:igmp_ipc_pulse_msg_handler: Handled 200 messages already. STOP!
Can somebody explain what these messages mean? How can I troubleshoot this issue??
