IGMP snoop

The ONT supports an IGMP snoop facility. The IGMP snoop facility snoops (looks
into) upstream join and leave messages, and maintains the multicast forwarding
database supported by the ONT hardware, which keeps track of the IP multicast
streams that subscribers are currently viewing.

Note —
For ONTs that have SoC technology on-board in a
two-Ethernet port device, only one Ethernet UNI port at a time can be
configured for IPTV and multicast streams.
Note —
The IGMP snoop facility only drops an IGMP message if the
IGMP message rate limit is exceeded.
