SYSTEMS AND METHODS OF CONFIGURING A LAYER-2 SWITCH FOR MULTICAST FILTERING

Systems and methods for reducing multicast IP packet bandwidth in a local area network carrying Internet protocol television (IPTV) traffic are disclosed. One embodiment of a system comprises: a layer-2 switch; a slave digital home communication terminal (DHCT); and a master DHCT. The layer-2 switch has a control channel and a plurality of data ports. The slave DHCT is coupled to a first data port of the plurality. The master DHCT is coupled to the layer-2 switch control channel. The master DHCT comprises logic for requesting the layer-2 switch, over the control channel, operate in a first configuration. In the first configuration, the layer-2 switch associates a layer-2 multicast address with the first data port, examines layer-2 multicast packets, and forwards the examined layer-2 multicast packets on the first data port only if the layer-2 destination address is the first layer-2 multicast address.
