This page allows you to enable or disable the spanning tree algorithm for the controller, modify its characteristics, and view the STP status.Table 3-6interprets 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	The time (in days, hours, minutes, and seconds) since a topology
Changed	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.
