Removing Group Members

The group members registered by IGMP snooping are removed under the following status.
• If after receiving an IGMP Report message for group registration, the group member interval expires before the device
receives another IGMP Report message, the switch removes the host from the group member. The setting for the group
member interval is 260 seconds.
• If an IGMP Leave message is sent from a host, the multicast router sends out an IGMP Specific Query (GSQ) message
to determine whether that the host has left the group.
• If after receiving the IGMP Leave message, the last member interval expires before the device receives another IGMP
Report message, the switch removes the host from the group member. The setting for the last member interval is 2
seconds.
