When IGMP fast leave processing is enabled, the ISAM willimmediately remove an SAP from the IP multicast group when it detects an IGMP 'leave' onthat SAP. Fast leave processing allows the switch to remove an SAP that sends a 'leave' fromthe forwarding table without first sending out group-specific queries to the SAP, and thusspeeds 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-leaveItem Description(2 of 2)Item DescriptionSyntax last-member-query-interval intervalno last-member-query-intervalContext configure>service>vpls>sap>igmp-snoopingDescription This command configures the maximum response time used in group-specific queries sent inresponse to ‘leave’ messages, and is also the amount of time between 2 consecutivegroup-specific queries. This value may be tuned to modify the leave latency of the network. Areduced 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 10Parameters interval — Specifies the frequency, in tenths of seconds, at which query messages are sent.Values: 1 — 50Item DescriptionSyntax [no] mrouter-port(1 of 2)
