DESCRIPTION
IGMP Snooping
Active
Select Active to enable IGMP Snooping to forward group multicast traffic only to ports
that are members of that group.
Querier
Select this option to allow the Switch to send IGMP General Query messages to the
VLANs with the multicast hosts attached.
Host Timeout
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).
IGMP Route Port
Forward
Enable the router forwarding function.
Port Information
Port
This field displays the port number.
Max Group Limit
Set the learning limit of multicast packets for the port (default is 1020).
Fast Leave
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.
Multicast VLAN
Set the default VLAN for multicast.
IGMP Filtering Profile
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.
