output definitions
Spanning Tree Path Cost
Mode
The Spanning Tree path cost mode for the switch (32 BIT or AUTO)
Configured through the bridge path cost mode command.
Msti The Multiple Spanning Tree Instance (MSTI) number. MSTI 0 repre-
sents the CIST. Configured through the bridge msti command.
STP Status The Spanning Tree state for the instance (ON or OFF).
Protocol The Spanning Tree protocol applied to the instance (STP, RSTP, or
MSTP). This value is not configurable for an MSTI. Configured
through the bridge protocol command.
Mode The Spanning Tree operating mode for the switch (1x1 or flat). Config-
ured through the bridge mode command.
Priority The Spanning Tree bridge priority for the instance. The lower the num-
ber, the higher the priority. Configured through the bridge msti prior-
ity command.
Bridge ID The bridge identifier for this Spanning Tree instance. Consists of the
bridge priority value (in hex) concatenated with the dedicated bridge
MAC address.
CST Designated Root The bridge identifier for the root of the flat mode CIST instance. This
field only appears when MSTP is active on the switch.
Cost to CST Root The cost of the path to the root for the flat mode CIST instance. This
field only appears when MSTP is active on the switch.
Next CST Best Cost 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.
Designated Root The bridge identifier for the root of the Spanning Tree for this instance.
Cost to Root Bridge The cost of the path to the root for this Spanning Tree instance.
Root Port The port that offers the lowest cost path from this bridge to the root
bridge for this Spanning Tree instance.
Next Best Root Cost The cost of the next best root port for this Spanning Tree instance.
