Msti STP Status Protocol Priority (Prio:SysID)
-----+----------+--------+---------------------
0 ON MSTP 32768 (0x8000:0x0000)
2 ON MSTP 32770 (0x8000:0x0002)

Topology Changes The number of topology changes detected by this Spanning Tree
instance since the management entity was last reset or initialized.
Topology age 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
days and hh:mm:ss).
Max Age The amount of time (in seconds) that Spanning Tree Protocol informa-
tion is retained before it is discarded. Configured through the bridge
max age command.
Forward Delay 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. Configured
through the bridge forward delay command.
Hello Time 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. Configured through the bridge
hello time command.
System Max Age The Max Age value for the root bridge.
System Forward Delay The Forward Delay value for the root bridge.
System Hello Time The Hello Time value for the root bridge.

Configured through the bridge path cost mode command.
Msti The Multiple Spanning Tree Instance (MSTI) instance number. Config-
ured through the bridge msti command. Note that MSTI 0 also repre-
sents the CIST instance that is always present on the switch.
Spanning Tree Status The Spanning Tree state for the MSTI (ON or OFF).
Protocol The Spanning Tree protocol applied to this instance. Configured
