Dell PowerSwitch S4128F-ON OS10 Enterprise Edition User Guide Release 10.4.3.0 - Page 624

• OS10 learns the multicast router interface dynamically based on the interface on which IGMP membership query is received. To assign a multicast router interface statically, use the ip igmp snooping mrouter interface interface-type command in VLAN INTERFACE mode. NOTE: IGMP snooping dynamically detects the mrouter interface based on IGMP queries that it receives. If there are more than one multicast routers connected to the snooping switch, one of them will send IGMP queries and the interface connected to that router is dynamically learnt as an mrouter port. You must configure the interfaces connected to other multicast routers as static mrouter port. • (Optional) Configure the IGMP version using the ip igmp version version-number command in VLAN INTERFACE mode. • (Optional) The fast leave option allows the IGMP snooping switch to remove an interface from the multicast group immediately on receiving the leave message. Enable fast leave with the ip igmp snooping fast-leave command in VLAN INTERFACE mode. • (Optional) Configure the time interval for sending IGMP general queries with the ip igmp snooping query-interval query-interval-time command in VLAN INTERFACE mode. • (Optional) Configure the maximum time for responding to a query advertised in IGMP queries using the ip igmp snooping query-max-resp-time query-response-time command in VLAN INTERFACE mode. • (Optional) Configures the time interval between group-specific IGMP query messages with the ip igmp snooping last- member-query-interval query-interval-time command in VLAN INTERFACE mode.
