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.
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 Specify the action to perform when the Switch receives an unknown multicast frame. Select
Frame Drop to discard the frame(s). Select Flooding to send the frame(s) to all ports.
