Hi,

It stands for Cisco Group Management Protocol (CGMP). It is used to help a switch decide which switch ports are members of which multicast groups so that traffic for each multicast group is forwarded to the devices that have joined a particular multicast stream. It does the same thing as IGMP but in a different way.

I was thinking it was 'CG Multicast Group' - Presumably name change!!!

I usually tell people that it's the equivalent of IGMP snooping.

Although, with that "C" in front, you just know that it's pretty much a Cisco only thing. :-)
