The Spanning Tree path cost mode for the switch (32 BIT or AUTO)
Configured through the
The CIST instance, referred to as bridge 1 when either STP (802.1D) or
RSTP (802.1W) is the active protocol in the flat mode.
The Spanning Tree state for the CIST instance (ON or OFF).
The Spanning Tree protocol applied to the instance (STP or RSTP).
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 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.
