Throttling 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 on this port from a host. Select this option to limit the number of multicast groups this port is allowed to join. Enter the number of multicast groups this port is allowed to join. IGMP throttling controls how the Switch deals with the IGMP reports when the maximum number of the IGMP groups a port can join is reached. Select Deny to drop any new IGMP join report received on this port until an existing multicast forwarding table entry is aged out. IGMP Filtering Profile Select Replace to replace an existing entry in the multicast forwarding table with the new IGMP report(s) received on this port. Select the name of the IGMP filtering profile to use for this port. Otherwise, select Default to prohibit the port from joining any multicast group. IGMP Querier Mode You can create IGMP filtering profiles in the Multicast > Multicast Setting > IGMP Filtering Profile screen. The Switch treats an IGMP query port as being connected to an IGMP multicast router (or server). The Switch forwards IGMP join or leave packets to an IGMP query port. Select Auto to have the Switch use the port as an IGMP query port if the port receives IGMP query packets. Select Fixed to have the Switch always use the port as an IGMP query port. Select this when you connect an IGMP multicast server to the port. Apply Cancel Select Edge to stop the Switch from using the port as an IGMP query port. The Switch will not keep any record of an IGMP router being connected to this port. The Switch does not forward IGMP join or leave packets to this port. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the nonvolatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. MES-3528 User's Guide 185
