Setting the Group Membership Interval Time
This optional configuration step is only valid for IGMPv3 environments and is available
both globally and for VLANs. The group membership interval time is the amount of time
in seconds that the switch waits for a report from a particular group on an interface
before deleting the interface from the entry. The valid range is between 2 to 3600 seconds.
The default setting is 260 seconds.
Global
To globally set the group membership interval time, in Global Configuration mode use
the igmpsnooping vlan group-membership-interval command.
Use the no version of the command to return the setting to the default value.
igmpsnooping group-membership-interval seconds
no igmpsnooping group-membership-interval
The following example sets all interfaces to have a group membership interval time of
360 seconds:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #igmpsnooping group-membership-interval 360
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
To verify the configuration, use the Privileged Exec show igmpsnooping command. This
command is described further in Showing the IGMP Snooping Configuration on page 172.
Per VLAN
To set the group membership interval time by VLAN, in VLAN database mode use the
igmpsnooping groupmembership-interval command. Use the no version of the
command to return the setting to the default value.
igmpsnooping vlan vlanid group-membership-interval seconds
Syntax Description seconds Sets the group membership interval time in
seconds in IGMPv3 environments. Valid ranges
are from 2 to 3600 seconds. The default is 260
seconds.
