NOTE:
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.
