We are having some issues with IGMP. For some reason we hadn't had IGMP snooping on, but now we do, which is a good thing.
Now however we are maxing out our members per group (set to 300) We have a case open (1274977) Specifically this is on the mDNS group 224.0.0.251.
We were told not to increase this limit.
What is the effect of hitting this limit? Does the switch flood after this point? or only send to those currently in the table? How are clients added/removed?
We keep getting this error :
<pim 204203> <ERRS> |pim| Could not add IP multicast group member 10.45.20.105
<pim 204299> <ERRS> |pim| Could not add member 00:03:4c:10:62:d6 to IP multicast group (10.45.20.105, 224.0.0.251), limit of 300 per group reached
Thanks
