rlIfMapOfOnPhPorts 1.3.6.1.4.1.9.6.1.101.54.3

Each bit in this octet string indicates that the correspondig port's ifOperStatus is ON if set. The mapping of port number to bits in this octet string is as follows: The port with the L2 interface number 1 is mapped to the least significant bit of the 1st octet, the port with L2 ifNumber 2 to the next significant bit in the 1st octet, port 8 to the most-significant bit of the in the 1st octet, port 9 to the least significant bit of the 2nd octet, etc. and in general, port n to bit corresponding to 2**((n mod 8) -1) in byte n/8 + 1
