Description

State

Current state of the port. By default, it is disabled, blocking, and forwarding.

NOTE: Other states like listening, learning are intermediate states which are not visible to the user.

Role

Current role of the port in the ring. If the port state is disabled, the role can be either Root or Designated. If the port state is disabled (Ethernet link is down) then the Role is Unknown.

Priority

The value of the port priority is contained in Port Identifier. All ports of a bridge will have a port identifier with format: [1 byte port number][1 byte port priority].

  • Port that carries packets to root bridge is root port. When there are multiple such ports exist, one with least Port Identifier becomes the root port, and others will become alternate ports.

  • Port Number: Port number cannot be configured. In the device the port Number (interface number) for port-1 is 1 and port number for port-2 is 2.

Port Path Cost

The contribution of this port to the path cost of paths towards the Root bridge which includes this port.
