Hello,

I have found in Cisco doc following info

In Cisco IOS Release 12.2(35)SE and later, you can also configure trunk ports as MVR receiver.

It is poosible to use MVR feature on trunk port on which multicast receiver (customer) traffic is QinQ (double VLAN tag) encapsulated.

For example trunk port to multicast receiver (customer) has VLAN 1000 enabled. I would like to check for IGMP queries comming on SVLAN/VLAN combination 1000.20, 1000.21 etc.

It is possible to do this with Cisco Catalyst switch ?

For example Alcatel Omnistack 6224 switchs supports and we are using this feature in our network.

What about Cisco switch ?

Best Regards,

Tomas
