Table 55 Advanced Application > Multicast > Multicast Setting 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. 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. IGMP Filtering Select Active to enable IGMP filtering to control which IGMP groups a subscriber on a port can join. Unknown Multicast Frame 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. 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. ES-4124 User's Guide 179
