Hi all!
I need to filter igmp host query messages coming to some ports of Nexus 5596.
I have configured an ACL:
ip access-list NOMCAST
10 deny igmp any any host-query
20 permit igmp any any
30 permit ip any any
statistics
and added it to interface:
int eth1/1
ip port access-group NOMCAST in
And ACL don't catch host query messages. I tried even to deny all igmp coming messages, without success.
At the same time when I denied ICMP in this ACL, it worked.
The same config with denying IGMP on Nexus 9000 works good.
I tried different IOS versions, and it didn't solved the issue.
Have you any thoughts?
