set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected interface or VLAN. Enabling fast-
leave allows the switch to immediately remove the layer 2 LAN interface from its forwarding table entry upon receiving an
IGMP leave message for that multicast group without first sending out MAC-based general queries to the interface.
You should enable fast-leave admin mode only on VLANs where only one host is connected to each layer 2 LAN port. This
prevents the inadvertent dropping of the other hosts that were connected to the same layer 2 LAN port but were still
interested in receiving multicast traffic directed to that group. Also, fast-leave processing is supported only with IGMP version
2 hosts.
