Description
This command enables fast leave. When IGMP fast leave processing is enabled, the ISAM will
immediately remove an SAP from the IP multicast group when it detects an IGMP 'leave' on
that SAP. Fast leave processing allows the switch to remove an SAP that sends a 'leave' from
the forwarding table without first sending out group-specific queries to the SAP, and thus
speeds up the process of changing channels ('zapping').
Fast leave should only be enabled when there is a single receiver present on the SAP.
When fast leave is enabled, the configured last-member-query-interval value is ignored.
Default
no fast-leave

Description
This command configures the maximum response time used in group-specific queries sent in
response to 'leave' messages, and is also the amount of time between 2 consecutive
group-specific queries. This value may be tuned to modify the leave latency of the network. A
reduced value results in reduced time to detect the loss of the last member of a group.
The configured last-member-query-interval is ignored when fast-leave is enabled on the SAP.
Default
10
Parameters
interval — Specifies the frequency, in tenths of seconds, at which query messages are sent.
