LABEL 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.
