6306 CO Modem IP Multicast Operation

An optional feature of the 6306 CO modem card is the ability to pass IP

Multicast traffic only to the subscribing port. The 6306 modem card

functions as a multi-layer switch and supports IGMP v1/v2 when con-

nected to the MIU (Management Interface Unit) card via the 100 Base-

T Ethernet backplane connection. The 6306 modem creates Port Table

data when a client joins a multicast group and forwards the IGMP mes-

sage upstream through the MIU to an IGMP-enabled Switch. When the

IP Multicast data is streamed back to the 6306, it replicates and for-

wards the IP Multicast streams ONLY to the ports with subscribing cli-

ents.
