■
maxAge
 — Displays the maximum age in seconds at which the stored 
configuration message information is judged to be too old and is 
discarded. This value is determined by the root bridge.
■
bridgeHelloTime
 — Displays the Hello time value, used when this 
bridge is the root bridge. This value is the time that elapses between 
the configuration messages generated by a bridge that assumes itself 
to be the root. 
■
helloTime
 — Displays the time that elapses between the 
configuration messages generated by a bridge that assumes itself to 
be the root.
■
bridgeFwdDelay
 — Displays the forward delay value used when this 
bridge is the root bridge. This value sets the amount of time that a 
bridge spends in the listening and learning states. 
■
forwardDelay
 — Displays the time that a bridge spends in the 
"listening" and "learning" states.
■
holdTime
 — Displays the minimum delay time in seconds between 
sending topology change Bridge Notification Protocol Data Units 
(BPDUs).
■
rootCost
 — Displays the cost of the best path to the root from the 
root port of the bridge. For example, one determining factor of cost is 
the speed of the network interface, that is, the faster the speed, the 
smaller the cost.
■
rootPort
 — Displays the port with the best path from the bridge to 
the root bridge. Will display a port number, or No Port.
■
priority
 — Displays the configurable value that is appended as the
