Example:
Switch(config)# ip igmp snooping
The default leave time is 1000 milliseconds.

setting, use the no ip igmp snooping
last-member-query-interval global configuration
command.

last-member-query-interval 1000
(Optional) Configures the IGMP leave time on the VLAN interface.
The range is 100 to 32767 milliseconds.
ip igmp snooping vlan vlan-id
last-member-query-interval time
Step 4
Example:
Switch(config)# ip igmp snooping vlan 210
Configuring the leave time on a VLAN overrides the
globally configured timer.
Note
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.
