This command enables fast leave. When IGMP fast leave processing is enabled, the 7210 SAS M will
Description
immediately remove a SAP or SDP from the multicast group when it detects an IGMP "leave" on that
SAP or SDP. Fast leave processing allows the switch to remove a SAP or SDP that sends a 'leave'
from the forwarding table without first sending out group-specific queries to the SAP or SDP, 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 or SDP.
When fast leave is enabled, the configured last-member-query-interval value is ignored.
no fast-leave
