configure igmp snooping timer <router_timeout> <host_timeout>
Description
Configures the IGMP snooping timers.
Syntax Description
router_timeout
host_timeout
Default
The router timeout default setting is 260 seconds. The host timeout setting is 260 seconds.
Usage Guidelines
Timers should be set to approximately 2.5 times the router query interval in use on the network. Specify
the following:
router timeout—The maximum time, in seconds, that a router snooping entry can remain in the
●
IGMP snooping table without receiving a router report. If a report is not received, the entry is
deleted. The range is 10 to 214,748,364 seconds (6.8 years). The default setting is 260 seconds.
host timeout—The maximum time, in seconds, that a group snooping entry can remain in the IGMP
●
snooping table without receiving a group report. If a report is not received, the entry is deleted. The
range is 10 to 214,748,364 seconds (6.8 years). The default setting is 260 seconds.
IGMP snooping expects at least one device on every VLAN to periodically generate IGMP query
messages. Without an IGMP querier, the switch eventually stops forwarding IP multicast packets to any
port, because the IGMP snooping entries will time out, based on the value specified in
router_timeout

The following command configures the IGMP snooping timers:
configure igmp snooping timer 600 600
