There is documentation on this from Extreme and you may be able to
change the way it is handling this.
I would recommend you go to a 460 or see if you can disable igmp
snooping and not have to process the Mcast.
If you are using this as a router then for sure you will need to
replace. The 150's 250's 350's 450's and older 8800 all have the same
broadcom chip and have the memory limitation.
-------
This is not our case.
After downgrade to:
ExtremeXOS version 12.4.1.7 v1241b7 by release-manager
The problem is gone.
This switch is acting only as IGMP device, no L3 routes, no ACLs.
FDB entries: 5368
Jarek Kasjaniuk gave me some hint that this is like an old error:
----------
PD4-654813987
When running ExtremeXOS 12.1 or later on a BlackDiamond 8800 a-series,
c-series, or e-
series switch, or the Summit family switches, you cannot add IP
multicast entries. The
following error message is displayed when trying to add entries:
Unable to Add IPmc sender entry/Unable to Delete IPmc sender entry
-----------
looks that it is back again..
