Controller Spanning Tree Status
Description
The STP version being used by the controller. Currently, only an IEEE
802.1D implementation is available.
The MAC address used by this bridge when it must be referred to in a
unique fashion. When it is concatenated with dot1dStpPriority, a
unique bridge identifier is formed that is used in STP.
The total number of topology changes detected by this bridge since the
management entity was last reset or initialized.
The time (in days, hours, minutes, and seconds) since a topology
change was detected by the bridge.
The bridge identifier of the spanning tree root. This value is used as the
Root Identifier parameter in all configuration BPDUs originated by this
node.
The number of the port that offers the lowest cost path from this bridge
to the root bridge.
The cost of the path to the root as seen from this bridge.
The maximum age of STP information learned from the network on any
port before it is discarded.
The amount of time between the transmission of configuration BPDUs
by this node on any port when it is the root of the spanning tree or trying
to become so. This is the actual value that this bridge is currently using.
This value controls how fast a port changes its spanning tree state when
moving toward the forwarding state. It determines how long the port
stays in each of the listening and learning states that 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.
Note
The minimum time period to elapse between the transmission of
configuration BPDUs through a given LAN port.

This is the actual value that this bridge is currently using, in
contrast to Stp Bridge Forward Delay, which is the value that
this bridge and all others would start using if this bridge were
to become the root.
At most, one configuration BPDU can be transmitted in any
hold time period.
