Hi James,
That's correct ;) 3550 only supports CGMP client.
Regards,
Hunt

Subject: 3550:CGMP server vs. client
I'm trying to understand the level of CGMP support in the 3550. Firstly, I'm
assuming that the CGMP server side refers to the router part and the client
side refers to the switch part. The first statement below indicates that
only the router part is supported. The second statement mentions "listening"
to CGMP - since CGMP messages would typically be sent from the router to the
switch, this tends to imply CGMP client functionality. I'd appreciate any
insight from either authorities or non-authorities :-)
"This software release provides CGMP-server support on your multilayer
switches; no client-side functionality is provided. The multilayer switch
serves as a CGMP server for devices that do not support IGMP snooping but
have CGMP-client functionality." from:

"You can configure the switch either to snoop on IGMP queries and PIM/DVMRP
packets or to listen to CGMP self-join or proxy-join packets" from:
