 IGMP SSM Range SSM (Source-Specific Multicast) Range allows the SSM-aware hosts and routers
run the SSM service model for the groups in the address range.
 Leave Proxy Enable Enable IGMP Leave Proxy. This feature can be used to avoid forwarding
unnecessary leave messages to the router side.
 Proxy Enable Enable IGMP Proxy. This feature can be used to avoid forwarding unnecessary
join and leave messages to the router side.
 Router Port Specify which ports act as IGMP router ports. A router port is a port on the
Ethernet switch that leads towards the Layer 3 multicast device or IGMP querier.
The Switch forwards IGMP join or leave packets to an IGMP router port.
 Auto:
Select “Auto” to have the Managed Switch automatically uses the port
as IGMP Router port if the port receives IGMP query packets.
 Fix :
The Managed Switch always uses the specified port as an IGMP
Router port. Use this mode when you connect an IGMP multicast
server or IP camera which applied with multicast protocol to the port.
 None:
The Managed Switch will not use the specified port as an IGMP
Router port. The Managed Switch will not keep any record of an
IGMP router being connected to this port. Use this mode when you
connect other IGMP multicast servers directly on the non-querier
Managed Switch and don’t want the multicast stream be flood to
uplink switch throught the port that connected to the IGMP querier.
 Fast Leave Enable the fast leave on the port.
 Throtting Enable to limit the number of multicast groups to which a switch port can belong.
