IGMP Fastleave:
Enable or disable Fast Leave on the port.
IGMP Querier:

displayed in IGMP status section.
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.
