Item Description
Fast Leave
Enable or disable the fast leave function for the port.
With the fast leave function enabled on a port, the device, when receiving an IGMP
leave message on the port, immediately deletes that port from the outgoing port list
of the corresponding forwarding table entry. Then, when receiving IGMP
group-specific queries for that multicast group, the device will not forward them to
that port. In VLANs where only one host is attached to each port, the fast leave
function helps improve bandwidth and resource usage.
IMPORTANT:
If fast leave is enabled for a port to which more than one host is attached, when one
host leaves a multicast group, the other hosts listening to the same multicast group will
fail to receive multicast data.
