10306 CO Modem IP Multicast Operation
An optional feature of the 10306 CO modem card is the ability to pass
IP Multicast traffic only to the subscribing port. The 10306 modem
card functions as a multi-layer switch and supports IGMP v1/v2 when
connected to the MIU (Management Interface Unit) card via the 100
Base-T Ethernet backplane connection. The 10306 modem creates Port
Table data when a client joins a multicast group and forwards the IGMP
message upstream through the MIU to an IGMP-enabled Switch. When
the IP Multicast data is streamed back to the 10306, it replicates and
forwards the IP Multicast streams ONLY to the ports with subscribing
clients.
