The Spanning Tree state for the instance (on or off).
The Spanning Tree protocol applied to the CIST (STP, RSTP, or
MSTP). Configured through the
The Spanning Tree operating mode for the switch (1x1 or flat). Config-
ured through the bridge mode
The Spanning Tree bridge priority for the instance. The lower the num-
ber, the higher the priority. Configured through the
command.
The bridge identifier for this Spanning Tree instance. Consists of the
bridge priority value (in hex) concatenated with the dedicated bridge
MAC address.
The bridge identifier for the root of the flat mode CIST instance. This
field only appears when MSTP is active on the switch.
The cost of the path to the root of the flat mode CIST instance. This
field only appears when MSTP is active on the switch.
The cost of the next best root port for the flat mode CIST instance. This
field only appears when MSTP is active on the switch.
The bridge identifier for the root of the Spanning Tree for this instance.
The cost of the path to the root for this Spanning Tree instance.
The port that offers the lowest cost path from this bridge to the root
bridge for this Spanning Tree instance.
The cost of the next best root port for this Spanning Tree instance.
The port that offers the next best (second lowest) cost path to the root
bridge for this Spanning Tree instance.
The count to limit the transmission of BPDU through the port.
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
days and hh:mm:ss).
The amount of time (in seconds) that Spanning Tree Protocol informa-
tion is retained before it is discarded. Configured through the
max age command.
