Port
The port of the switch.
Port ID
The port identifier used by the STP protocol, consisting of the priority and
the logical port index of the bridge port.
Role
The role of a port is assigned based on whether it is part of the active
topology connecting the bridge to the root bridge (i.e., root port),
connecting a LAN through the bridge to the root bridge (i.e., designated
port); or is an alternate or backup port that may provide connectivity if
other bridges, bridge ports, or LANs fail or are removed.
State
Displays the current state of this port in the Spanning Tree.
Path Cost
The path cost of the port contributed to the paths towards the spanning
tree root which include this port. It can be a value assigned by the Auto
setting or any explicitly configured value.
Edge
The current STP port (operational) Edge Flag. An Edge Port is a switch
port to which no bridges are attached. The flag may be automatically
computed or explicitly configured. Each Edge Port transits directly to the
Forwarding Port State, since there is no possibility of it participating in a
loop.
Point-to-Point
Indicates a connection to exactly another bridge. The flag may be
automatically computed or explicitly configured. The point-to-point
properties of a port affect how fast it can transit to STP states.
Uptime
The time since the bridge port was last initialized.
3.6.4.9 Port Status
This page displays the STP CIST port status for physical ports of the switch.
