LABEL DESCRIPTION
IGMP Action Use these settings to configure multicast group membership discovery.
Active Select None to disable multicast group membership discovery on the Switch.
Select Snooping to enable IGMP/MLD snooping to forward group multicast traffic only to
ports that are members of that group.
Select Proxy to enable IGMP/MLD proxy to decrease subscriber's join/leave messages
forwarding in a group.
Enable MLD Enables Multicast Listener Discovery version one (MLD v1) and version two (MLD v2) on
the Switch. See Section 24.1.6 on page 218 for information about MLD.
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.
Leave Timeout Enter an IGMP leave timeout value (from 1 to 16,711,450) in seconds. This defines how
many seconds the Switch waits for an IGMP report 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.
