set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected
VLAN. Enabling fastleave allows the switch to immediately remove the layer 2 LAN interface,
participating in the VLAN, 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. Fast-leave admin mode should be enabled only on VLANs where only one host is
connected to each layer 2 LAN port, to prevent the inadverdent 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.
