Nexus 5596 igmp filtering

[Vladimir Pisarenko]

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?

Hello Vladimir,

You can try with IGMP snooping per VLAN which filters all those messages.
