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 host.
Leave Timeout Enter an IGMP leave timeout value (from 1 to 16,711,450) in seconds. This
defines how many seconds the switch waits 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.
