Root ID [dot1dStpDesignatedRoot
]
The bridge identifier of the root of the Spanning Tree. This value is used as the Root
Identifier in all Configuration Bridge PDUs originating from this node.
Root Port [dot1dStpRootPort]
The number of the port offering the lowest cost path from this bridge to the root
bridge.
Root Cost [dot1dStpRootCost]
The cost of the path to the root bridge from this bridge.
Maximum Age [dot1dStpMaxAge] This is the actual value the
bridge is currently using.
The maximum age of Spanning Tree protocol information learned from the network
on any port before it is discarded, in seconds.
Hello Time [dot1dStpHelloTime] This is the actual value the
bridge is currently using.
The amount of time between the transmission of Configuration bridge PDUs by this
node on any port when it is the root of the Spanning Tree or trying to become so, in
seconds.
Hold Time [dot1dStpHoldTime]
The interval length during which no more than two Configuration bridge PDUs can
be transmitted by this node, in hundredths of a second.
Forward Delay [dot1dStpForwardDelay] This is the actual value the
bridge is currently using.
Controls how fast a port changes its spanning state when moving towards the For-
warding state. This value determines how long the port stays in each of the Listening
and Learning states, which precede the Forwarding state. This value is also used
when a topology change has been detected and is underway to age all dynamic
entries in the Forwarding database.
Bridge Priority [dot1dStpPriority]
A value which is concatenated to the Bridge MAC address and the result is the
Bridge ID. The Bridge ID is used in the Spanning Tree Protocol.
