DESCRIPTION

IGMP Snooping

Use these settings to configure IGMP Snooping.

Active

Select Active to enable IGMP Snooping to forward group multicast traffic only to

ports that are members of that group.

Host Timeout

Specify 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.

Leave Timeout

Enter an IGMP leave timeout value (from 1 to 16,711,450) in seconds. 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

from a host.

802.1p Priority

Select a priority level (0-7) to which the Switch changes the priority in outgoing

IGMP control packets. Otherwise, select No-Change to not replace the priority.

IGMP Filtering

Select Active to enable IGMP filtering

to control which IGMP groups a subscriber

on a port can join.

Note: If you enable IGMP filtering, you must create and assign

IGMP filtering profiles for the ports that you want to allow to
join multicast groups.

Unknown

Multicast Frame

Specify the action to perform when the Switch receives an unknown multicast

frame. Select Drop to discard the frame(s). Select Flooding to send the frame(s)

to all ports.
