How to Configure IGMP Snooping and MVR
To globally reset the IGMP leave timer to the default
setting, use the no ip igmp snooping
last-member-query-interval global configuration
command.
Configuring the leave time on a VLAN overrides the
globally configured timer.
To remove the configured IGMP leave-time setting from
the specified VLAN, use the no ip igmp snooping vlan
vlan-id last-member-query-interval global configuration
command.
