Enable or disable the IGMP snooping fast leave function. If enabled, the
membership is immediately removed when the system receive the IGMP leave
message.
If the state is enable, it allows the switch to be selected as a IGMP Querier (sends
IGMP query packets). It the state is disabled, then the switch can not play the role
as a querier.
NOTE: that if the Layer 3 router connected to the switch provides only the IGMP
proxy function but does not provide the multicast routing function, then this
state must be configured as disabled. Otherwise, if the Layer 3 router is not
selected as the querier, it will not send the IGMP query packet. Since it will
not also send the multicast-routing protocol packet, the port will be timed out
as a router port.
When enabled, multiple IGMP reports or leave for a specific (S, G) will be
integrated into one report only before sending to the router port.
Specify to enable or disable the data driven learning state.
Specify to enable or disable the data drive learning aged out option.
Specify the version of IGMP packet that will be sent by this port. If an IGMP packet
received by the interface has a version higher than the specified version, this
packet will be dropped.

Description
This section is used to designate a range of ports as being connected to multicast-
enabled routers. This will ensure that all packets with such a router as its destination
will reach the multicast-enabled router regardless of the protocol.
This section is used to designate a range of ports as being not connected to
multicast-enabled routers. This ensures that the forbidden router port will not
propagate routing packets out.
Displays router ports that have been dynamically configured.
Select the appropriate ports individually to include them in the Router Port
configuration.
