When IGMP snooping is globally enabled, IGMP snooping is enabled on all the existing VLAN
interfaces. When IGMP snooping is globally disabled, IGMP snooping is disabled on all the existing
VLAN interfaces.
VLAN IDs 1002 to 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in IGMP
snooping.
Configuring the leave timer on a VLAN overrides the global setting.
The IGMP configurable leave time is only supported on devices running IGMP Version 2.
The configuration is saved in NVRAM.
This example shows how to globally enable the IGMP leave timer for 2000 milliseconds:
Switch(config)# ip igmp snooping last-member-query-interval 2000
This example shows how to configure the IGMP leave timer for 3000 milliseconds on VLAN 1:
Switch(config)# ip igmp snooping vlan 1 last-member-query-interval 3000
You can verify your settings by entering the show ip igmp snooping privileged EXEC command.
