All things related to multicast

[David Farmer <>]

I haven't tried them out yet but the new Cisco Catalyst 3560-C and 
2960-C Series Compact Switches look interesting for what you want.

http://www.cisco.com/en/US/prod/collateral/switches/ps11527/ps11289/data_sheet_c78-639705_ps11290_Products_Data_Sheet.html

But if they are anything like their 3560 and 2960 namesakes, and there 
bigger brother the 3750, then the should do nicely for what you want.
