Description
Port
The port identifier.
Port ID
The port identifier used by the RSTP 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 RSTP 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 transitions 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 one other bridge. The flag may be
automatically computed or explicitly configured. The point-to-point properties
of a port affect how fast it can transition RSTP states.
Uptime
The time since the bridge port was last initialized.
