Configures the IGMP snooping timers.
|router_timeout||Specifies the time in seconds before removing a router snooping entry.|
|host_timeout||Specifies the time in seconds before removing a host‘s group snooping entry.|
|vrname||Specifies a virtual router.|
|vlan_name||Specifies the VLAN name. If no VLAN is specified, the setting is applied to all existing VLANs.|
The router timeout default setting is 260 seconds. The host timeout setting is 260 seconds.
NoteThe host_timeout value should be less than or equal to the query timeout value, which is defined by the following: (query_interval x robustness) + query_response_interval.
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 time out, based on the value specified in host_timeout or router_timeout.
The following example configures the IGMP snooping timers:
configure igmp snooping timer 600 600
