The number of topology changes detected by this Spanning Tree
instance since the management entity was last reset or initialized.
The amount of time (in hundredths of seconds) since the last topology
change was detected by this Spanning Tree instance (hh:mm:ss or dd

CIST instance.
The amount of time (in seconds) that a port will remain in the Listening
state and then the Learning state until it reaches the forwarding state.
This is also the amount of time used to age out all dynamic entries in
the Forwarding Database when a topology change occurs. MSTIs
inherit this value from the CIST instance.
The amount of time (in seconds) between the transmission of Configu-
ration BPDUs on any port that is the Spanning Tree root or is attempt-
ing to become the Spanning Tree root. MSTIs inherit this value from
the CIST instance.
The Max Age value for the root bridge.
The Forward Delay value for the root bridge.
The Forward Delay value for the root bridge.
Implicit command for displaying the Spanning Tree bridge configu-
ration for the flat mode CIST instance or a 1x1 mode VLAN
instance.
Explicit command for displaying the Spanning Tree bridge configu-
ration for the CIST instance regardless of which mode (1x1 or flat)
is active on the switch.
Explicit command for displaying the Spanning Tree bridge configu-
ration for a VLAN instance regardless of which mode (1x1 or flat)
is active on the switch.
