3.3.1.4 CST Port Status

The port role types of the interface:
 Root Port: It is a concept of STP. Every non-root switch has one root port. The lowest cost of the path to the
root switch will be the root port.
 Master Port: It is a concept of MSTP. It must meet two conditions: one is the root port in CIST; the other one
is an edge port. The edge port is the port which connects two regions.
 Designated Port: The port responsible for forwarding data to the downstream network segment or device.
 Alternate Port: The standby port for the root port or master port. If a root port or master port is blocked, the
alternate port becomes the new root port or master port.
