Use the igmp-snooping fast-leave command to enable the fast leave feature on the
current port or group of ports.

on the current port or group of ports.
By default, the fast leave feature is disabled.
Note that:
z This command works on IGMP Snooping–enabled VLANs and VLANs with IGMP
enabled on the corresponding VLAN interfaces.
z If you do not specify any VLAN when you use this command in Ethernet port view,
the command will take effect no matter which VLAN the port belongs to; if you
specify a VLAN or multiple VLANs, the command will take effect only if the port
belongs to the specified VLAN(s).
