Description
Enable or disable the fast-leave function for the port.
With the fast-leave function enabled on a port, when the switch receives an IGMP leave
message on the port, it immediately deletes that port from the outgoing port list of the
corresponding forwarding table entry. Then, when the switch receives IGMP
group-specific queries for that multicast group, it does not forward them to that port.
On a port that has only one host attached, you can enable fast-leave processing to save
bandwidth and resources. However, on a port that has multiple hosts attached, do not
enable fast-leave processing if you have enabled dropping unknown multicast data for the
VLAN which the port belongs to. Otherwise, if a host on the port leaves a multicast group,
the other hosts attached to the port in the same multicast group cannot receive the multicast
data for the group.
