7.77 Port ID

Description
The Port ID parameter contains 16 bits, which show the port priority and the unique port number
in the bridge. The first eight bits indicate the port priority, and the later eight bits indicate the
port number. The port ID represents the priority in the spanning tree. If the value of the port ID
is smaller, the port priority in the bridge is higher. To enable the RSTP to be compatible with
the STP, the port priority is represented by eight bits, of which the later four bits are 0 for easy
management.
Impact on the System
This parameter is for query only. The system is not affected.
Values
The parameter value is in decimal system. For example, Port ID = 32769.
