Configuring Optional Multicast Routing Features - Cisco 3032 Software Configuration Manual

Configuring Optional Multicast Routing Features

Beginning in privileged EXEC mode, follow these steps to configure the switch itself to be a statically
connected member of a group (and enable fast switching). This procedure is optional.
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
ip igmp static-group group-address
Step 4 end
Step 5 show ip igmp interface [interface-id]
Step 6 copy running-config startup-config
To remove the switch as a member of the group, use the no ip igmp static-group group-address
interface configuration command.

Enabling CGMP Server Support
The switch serves as a CGMP server for devices that do not support IGMP snooping but have CGMP
client functionality. CGMP is a protocol used on Cisco routers and multilayer switches connected to
Layer 2 Catalyst switches to perform tasks similar to those performed by IGMP. CGMP is necessary
because the Layer 2 switch cannot distinguish between IP multicast data packets and IGMP report
messages, which are both at the MAC-level and are addressed to the same group address.
Beginning in privileged EXEC mode, follow these steps to enable the CGMP server on the switch
interface. This procedure is optional.
Command
Step 1 configure terminal
Step 2 interface interface-id
