10.4.6.2.12 set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected VLAN.
Enabling fast-leave 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 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.
Syntax
set igmp fast-leave <1-4093>
no set igmp fast-leave <1-4093>
<1-4093> - VLAN ID (Range: 1 - 4093).
no - This command disables IGMP Snooping fast-leave admin mode on a selected VLAN.
