The registered IP multicast group is deleted if an IGMP Report message is not received within the valid time.
Use the no form to return to the default setup.
Prompt
xg(config-vlan)#
Command syntax

no ip snooping group-member-interval
Parameter

seconds in RFC.) The recommended value is as follows.
Group-member-interval = Query Interval ¯ 2 + 10 (seconds)
