• Configuration Name. Specify an identifier used to identify the configuration currently
being used.
The name can be up to 32 alphanumeric characters.
• Configuration Revision Level. Specify an identifier used to identify the configuration
currently being used.
The values allowed are between 0 and 65535. The default value is 0.

last changed.
Topology Change Count The number of times that the topology changed for the CST.
Topology Change The value of the topology change parameter for the switch indicating
whether a topology change is in progress on any port assigned to the CST.
Possible values are True and False.
Designated Root The bridge identifier of the root bridge. It is made up from the bridge priority
and the base MAC address of the bridge.
Root Path Cost Path cost to the designated root for the CST.
Root Port Port to access the designated root for the CST.
Max Age (secs) The maximum age timer controls the maximum length of time in seconds
