hi,
we have a stack with X460-G2 in summitstack.
EXOS is running in 15.6.3.1 v1563b1-patch1-8
The stacks has 6 members, with 2 uplink 10Gb/s to Cisco Core.
I think we have multicast problem : in logs, i have :
Slot-1: exosSnoop: snoop_cache_unresolved:851: snoop_cache_unresolved failed to send report
What does it mean ?
Anyone know that ? how to correct it ?
Thx for your help.

Herve,
What are the other switches in the stack and what version of firmware are you running.. can you post the output of "show ver" and "show slot" ? Looks like you are exceeding queue space on the mcast and the message indicates the software is trying to protect the integrity of the CPU in the master of the stack. Are the mcast queues very large, I assume you are running a very large multicast setup? You can see the queue "show mcast cache" - send the last page of that too.. Do you by chance have a TAC case open for this?
Bill

Also .. "show igmp snooping detail" - Are there any loops possibly on the network? This message indicated there is some device that is consuming the cache, it is only thrown if there are 2048 packets to be processed by the snooping module. Seems to be a device not playing nice, are there any EAPS rings or anything else in the environment?

On cisco core, there pim sparse-dense mode on all vlan on each vrf. The RP for each vrf, is the loopback of the vrf.
On exos, nothing for multicast, just :
#
# Module mcmgr configuration.
#
enable igmp snooping forward-mcrouter-only vr VR-Default
configure igmp snooping filters per-vlan
configure forwarding ipmc lookup-key group-vlan
configure mcast ipv4 cache timeout 90
The configure igmp snooping filters per-vlan is new since this afternoon. I know it's per port by default.
Thx for you help.

What is the Multicast configuration in this network? Is there PIM-SM? If so can you provide the PIM configuration from the XOS side?
