This page allows you to enable or disable the spanning tree algorithm for the controller, modify its
characteristics, and view the STP status.Table 3-6 interprets the current STP status for the controller.
Table 3-6 Controller Spanning Tree Status
Parameter Description
Spanning Tree Specification The STP version being used by the controller. Currently, only an IEEE
802.1D implementation is available.
Base MAC Address 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.
Topology Change Count The total number of topology changes detected by this bridge since the
management entity was last reset or initialized.
Time Since Topology
Changed
The time (in days, hours, minutes, and seconds) since a topology
change was detected by the bridge.
Designated Root 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.
Root Port The number of the port that offers the lowest cost path from this bridge
to the root bridge.
Root Cost The cost of the path to the root as seen from this bridge.
