16.1.3 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.
