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.
