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.
Querier Select this option to allow the Switch to send IGMP General Query messages to the VLANs
with the multicast hosts attached.
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.
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.
