IGMP Fast leave:

IGMP Querier:
Enable or disable the IGMP query function. The IGMP query information will be
displayed in IGMP status section.
IGMP Router Port:
Allows user choosing three IGMP router port modes as follows:
a.
Auto:
Dynamic IGMP router port mode, where the system detects
multicast source then set the port to router port automatically.
b.
Static:
System will be forced to forward IGMP Join or Leave control
packet to another switch via an indicate port.
c.
Forbidden:
Allows user to set port as a non-router port.
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 fast leave 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.
