Forwarding port list 1. OLT It is presented by member port list. Each member port is identified by 4-byte format, same as TC of EponDeviceIndex. The actual length of this string depends of the number of member ports in the port list. The relationship is: Length of the string = 4 * (NUM of member ports) For example, if device 1, port 1/2 and 2/3 is the member ports, then this object will be presented as: 01 01 02 00 01 02 03 00 2. ONU It is presented by member port list. Each member port is identified by 2-byte format, One for slot ID, the last for port ID. The actual length of this string depends of the number of member ports. If the ONU is fixed (not modulized), set slot ID to 0, the NMS could ignore the slot info. Note that, slot here shall follow the last byte definition of EponCardIndex to indicate the main-slot and sub-slot index. The relationship is: Length of the string = 2 * (NUM of member ports) For example, if port 1/2 and 3/4 is the member ports of the group, then the object is presented as: 01 02 03 04
