The Multicast Address to Vcl Mapping table. Each entry in this table associates a multicast address representing a video stream with a Vcl. All of the entries in this table are assumed to be unique, not only in terms of index, but in terms of (index, multicast address) <-> (ifIndex, vpi, vci). Note that the Vcl type for this table should always be 'other', denoting cell relay pass-through. We are not terminating the IP stream on the MALC. Also note that the Vcls that this table refer to are the ones originating at the Video Head-End, coming into the MALC Uplink card.
