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.
