This object specifies ports to which multicast datagrams belonging to this (source, group) pair to be forwarded. The value in each octet contains a bit maps of 8 ports, that the significant bit represents the lowest port and the least significant bit represent the highest port. The first octet represents ports 1 to 8, the next octet represents ports 9 to 16, ..., etc. If the bit value is set then the corresponding port will have multicast datagrams to be forwarded. The tunnel ports mapping is put in the next a3ComDvmrpForwardOutPortsTunnel object.
