We are currently using 2960Gs with IGMP
querier enabled
I'm thinking a
4948 or 3750G would work.
It sounds like you're using the L2 'ip igmp snooping querier' function in your
2960.
I don't think that feature is available in the 4948.
IGMP snooping as a function of enabling multicast
What about the new 3750X and 3560X models?

time). Currently all of the sources and receivers are in the same VLAN but we

I don't think that's true. I think 3750s do multicast in hardware.

The total of the multicast sources is 4Gbps so I don't think a 7200 would
work unfortunately. The router would mostly serve as a IGMP querier and
would only ever route 2-3 streams at a time, so I think my worst case would
be sum of all sources + 3
Ours definiately do, otherwise I would imagine all that IPTV traffic on
Are you using the 3750s for layer3 or just layer2? If just layer2 what are you
using as your as your multicast router?
It is looking like both the 3750 and 4948 do hardware multicast. Any reason
to pick one over the

Mixed, but generally L3. The uplink links are
