DESCRIPTION
Use these settings to configure IGMP snooping.
Select Active to enable IGMP Snooping to forward group multicast traffic only to ports
that are members of that group.
Select this option to allow the Switch to send IGMP General Query messages to the VLANs
with the multicast hosts attached.
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.
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.
