IGMP Snooping Fundamentals
1. Ports
Router Port: Indicates the Managed Switch port directly connected to the multicast router.
Member Port: Indicates a Managed Switch port connected to a multicast group member.
2. Timers
Router Port Time: Within the time, if the Managed Switch does not receive IGMP query message from the router port, it will
consider this port is not a router port any more. The default value is 300 seconds.
Member Port Time: Within the time, if the Managed Switch does not receive IGMP report message from the member port, it will
consider this port is not a member port any more. The default value is 260 seconds.
Leave Time: Indicates the interval between the Managed Switch receiving a leave message from a host and the Managed
Switch removing the host from the multicast groups. The default value is 1 second.
