Congure IGMP Setup
Path: Network > LAN > IGMP Setup
IGMP snooping allows the controller to ‘listen’ in on IGMP network trac through the controller. This then allows
the controller to lter multicast trac and direct this only to hosts that need this stream. This is helpful when
there is a lot of multicast trac on the network (say from an IPTV application) where all LAN hosts do not need to
receive this multicast trac. Enabling IGMP snooping allows the controller to regulate the amount of multicast
trac on the network, to prevent ooding all LAN hosts. Active IGMP snooping is referred to IGMP Proxy, and this
is available on your controller.
1. Click Network > LAN > IGMP Setup.
2. Next to IGMP Proxy, toggle to ON.
3. Click Save.
4. Click Add New Network Address to specify the IP network and host addresses of the multicast sources.
5. Enter the network address and mask length. Click Save.
