Usage Add or remove multicast router ports. All (layer-2) multicast traffic will be
forwarded on multicast router ports, see section 18.1.1 .

ports.

ports.

18.3.5 Multicast Router Timeout
Syntax [no] multicast-router-timeout <1-2147483647>
Context IP Configuration context
Usage Set the ”other IGMP Querier present” timeout (sec). The same interval is
used for all interfaces.
Timeout for learned multicast router ports. With IGMP, and IGMP Snooping
for switches, the elected querier is a critical component for successful oper-
ation. If it is lost, or suddenly gets a new IP address, another device must
take over. This timeout adjusts the timeout before this device can take over.
”no multicast-router-timeout” resets the ”other IGMP Querier present”
timeout to the default setting (”300”).
Use ”show multicast-router-timeout” to view configured ”other IGMP
Querier present” timeout.
The timeout should never be set lower than the IGMP Query Interval!
Default 300 (sec)
18.3.6 Show IGMP Snooping Status Information
Syntax show ip igmp
Context Admin Exec context
