Admin Mode Select the interface mode for the selected interface for IGMP Snooping for the
switch from the pulldown menu. The default is disable.
Group Membership Interval Specify the amount of time you want the switch to wait for a report for a
particular group on a particular interface before it deletes that interface from
the group. The valid range is from (2 to 3600) seconds. The default is 260
seconds.

on an interface because it did not receive a report for a particular group on
that interface. Enter a value greater or equal to 1 and less than the Group
Membership Interval in seconds. The default is 10 seconds. The configured

Specify the amount of time you want the switch to wait to receive a query on
an interface before removing it from the list of interfaces with multicast
routers attached. Enter a value between 0 and 3600 seconds. The default is 0
seconds. A value of zero indicates an infinite timeout; i.e., no expiration.
Fast Leave Admin Mode Select the Fast Leave mode for the a particular interface from the pulldown
