Internet Group Management Protocol (IGMP) Status

The switch uses the CLI to display the following IGMP status on a per-VLAN basis:

Show Command	Output

show ip igmp	Global command listing IGMP status for all VLANs configured
	in the switch:
	• VLAN ID (VID) and name
	• Active group addresses per VLAN
	• Number of report and query packets per group
	• Querier access port per VLAN
show ip igmp <vlan-id>	Per-VLAN command listing above IGMP status for specified
	VLAN (VID)

show ip igmp group <ip-addr> Lists the ports currently participating in the specified group, with port type, Access type, Age Timer data and Leave Timer data.

For example, suppose that show ip igmp listed an IGMP group address of

224.0.1.22.You could get additional data on that group by executing the

following:
