DESCRIPTION
Select Active to enable IGMP Snooping to forward group multicast traffic only to ports
that are members of that group.
Select this option to allow the Switch to send IGMP General Query messages to the
VLANs with the multicast hosts attached.
pecify the time (from 1 to 16 711 450) in seconds that elapses before the Switch
removes an IGMP group membership entry if it does not receive report messages from
the port. (default is 300 seconds).
Enable the router forwarding function.
This field displays the port number.
Set the learning limit of multicast packets for the port (default is 1020).
Enable the port's fast leave function (when the port receives IGMP departure packets,
it deletes the port from the multicast group).
Enter an IGMP fast leave timeout value (from 200 to 6,348,800) in miliseconds. Select
this option to have the Switch use this timeout to update the forwarding table for the
port. In fast leave mode, right after receiving an IGMP leave message from a host on
a port, the Switch itself sends out an IGMP Group-Specific Query (GSQ) message to
determine whether other hosts connected to the port should remain in the specific
multicast group. This helps speed up the leave process. This defines how many
seconds the Switch waits for an IGMP report before removing an IGMP snooping
membership entry when an IGMP leave message is received on this port from a host.
Set the default VLAN for multicast.
Add or delete IGMP filtering profiles. Set the IGMP filtering for the port. When IGMP
filter is used, then only allowed multicasts can be used for learning. Multicasts banned
by the IGMP filter cannot be used for learning.
