Trying to enable igmp snooping on a 3500XL 12.0(5) switch.

When I enter ip igmp ?, I get ambiguous command.
 When I enter ip igmp, I get incomplete command.   (!)

You can use CGMP instead of IGMP, CGMP is supported

config t
cgmp leave-processing

See if that works

Check out the following doc

Really.  I've been instructed to turn on multicasting throughout the network.  I've got the 6506 and 6509 multicast enabled.  What good will it do if I can't do igmp snooping on the switches?  They are all 3500 or 3500XL.  Just got in some 2960s.  Any work arounds without replacing equipment?
