376CHAPTER 18: CONFIGURING AND MANAGING IGMP SNOOPING

Displaying Multicast To display information about the multicast receivers only without also Receivers displaying all the other multicast information, use the following

command:

display igmp receiver-table [vlan vlan-id] [group group-ip-addr/mask-length]

Use the group parameter to display receivers for a specific group or set of groups. For example, to display receivers for multicast groups 237.255.255.1 through 237.255.255.255, in all VLANs, type the following command:

WX1200# display

igmp receiver-table group 237.255.255.0/24
