Configuring IGMP Snooping
11-13
Displaying the List of Interfaces IGMP Fast-leave is Enabled
To display the list of the VLANs and ports which IGMP fast-leave feature is enabled on, use the
show ip igmp snoop fast-leave
command in Privileged mode. If you enable IGMP fast-
leave feature, the system immediately removes a port when it detects an IGMP version 2 leave
message on that VLAN or port.
The following is the sample output from show ip igmp snoop fast-leave command:
# show ip igmp snoop fast-leave
vlan : 1
port : 1/1

Displaying IGMP Group Membership Time
To display IGMP group membership time which defines how long a group will remain active
on an interface in the absence of a group report, use the show ip igmp snoop membership
timeout
command in Privileged mode.
# show ip igmp snoop membership timeout
260
