Fast Leave: The Managed Switch can be configured to immediately delete a
member port of a multicast service if a leave packet is received at that port and the
fastleave function is enabled for the parent VLAN. This allows the Managed witch to
remove a port from the multicast forwarding table without first having to send an
IGMP group-specific query to that interface.
