An entry in the Multicast Address to Vcl Mapping table. This entry is used to associate a multicast address with a Vcl. Step-wise Procedures to set up a Multicast Vcl Mapping profile Once the Vcl that carries the video stream is created, the following steps are taken to provision a Multicast Address to Vcl Mapping: (1) The manager obtains a unique atmMulticastAddressVclMapIndex by reading the atmMulticastAddressVclMapIndexNext object. (2) Next, the manager creates a row in the atmMulticastAddressVclMapTable by setting atmMulticastAddressVclMapRowStatus to createAndGo. The agent checks the sanity of the Vcl, domain index, and multicast address. The row creation fails if: - the specified Vcl does not exist, - the specified Vcl is not of the correct type for multicasting, - the routing domain index is outside of the supported range, - the multicast address is not of the correct format. (3) The manager promotes the row in the atmMulticastAddressVclMapTable when the 'set' completes.
