Multicast Traffic - IGMP Snooping

We are currently running a Hybrid CATOS/IOS Environment with Sup2 and MSFC2 Line Cards. The Sup Version is

8.4(3) and MSFC is 12.1(26)we want to run multicast traffic between our internal network to our external Govt Provider in the form of a particular Video Conferencing Client. We have been told that seeing we are running CATOS on our Sup2 engines we will get periodic dropouts of multicast traffic between our internal and external Depts if we don't upgrade to an Native IOS Environment. They are saying that we cannot disable igmp snooping on a per-Vlan basis under our Current Hybrid Environment unless we upgrade to Native IOS. Can we disable igmp snooping on a per-vlan basis using our current CATOS version or do we have to upgrade to a Native IOS Software set ??

Thanks Simon

Re: Multicast Traffic - IGMP Snooping

at the catOS level, you only have the ability to enable igmp, not per vlan.

on the msfc SVIs you should then be able to enable or disable igmp at the VLAN interface level.

this may provide the abilities you are looking for.

try this and let us know if any further issues or post your config for review.
