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.
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.
