Layer 2 multicast switching capacity

Will you tell me the "Layer 2 multicast switching capacity" of the catalyst switches(1924,2900,2950,3500,3550,3750 ,6500) and router 7600)?

Is it same as the Layer 2 unicast switching capacity?

Also, the layer 2 multicast switching is processed by hardware or software?

Thanks.

Re: Layer 2 multicast switching capacity

Probably not. Why? Because multicast is copied on to all ports or with IGMP and/or CGMP enabled, copied only to ports interested in such traffic. It takes more processing then a mac-address-table lookup used for unicast.

All switching occurs in hardware ASICs.
