Configure the Multicast Router Port Time-Out Value

Configuring the multicast router port time-out value sets the IGS router port-purge time-out value, after which the port gets deleted if no IGMP router control packets are received. Before you can configure IGS features, you must configure your network environment, as described in Topology Example.

1. Configure the multicast router port time-out value.

   SEFOS# configure terminal
   SEFOS(config)# ip igmp snooping mrouter-time-out 60
   SEFOS(config)# end

   Dynamically learned mrouter entries are deleted after 60 seconds.

2. Review the configuration.

   SEFOS# show ip igmp snooping globals
