Issue Description
Q: What is the port information of nas-port-id when a user accesses MA5200G via TRUNK port?
Alarm Information
No

Handling Process
No

Root Cause

A: When a user accesses MA5200G via TRUNK port, Nas-Port-Id information slot, port information and the actual Trunk port number are identical, but there is one difference, that is, the number of sub-slot of trunk is fixed to 2.
For example, we configure the trunk port as:
[MA5200G]interface Eth-Trunk 1/0/3
So, what is uploaded is slot number=1, sub-slot number=2, port number=3; that is, the information on Nas-Port-Id is “slot=1; subslot=2; port=3; vlanid=xxxx” (if PPPOE+, Option82, or VBAS is used, the format agrees with relevant protocols, but the information of subslot is fixed to 2).
