Term Definition
MST Instance ID The ID of the existing multiple spanning tree (MST) instance identifier. The value is 0–4094.
Port Identifier The port identifier for the specified port within the selected MST instance. It is made up from the port
priority and the interface number of the port.
Port Priority The priority for a particular port within the selected MST instance. The port priority is displayed in
multiples of 16.
Port Forwarding Current spanning tree state of this port.
State
Port Role Each enabled MST Bridge Port receives a Port Role for each spanning tree. The port role is one of
the following values: Root Port, Designated Port, Alternate Port, Backup Port, Master Port or
Disabled Port
Auto-Calculate Port Indicates whether auto calculation for port path cost is enabled.
Path Cost
Port Path Cost Configured value of the Internal Port Path Cost parameter.
Designated Root The Identifier of the designated root for this port.
Root Path Cost The path cost to get to the root bridge for this instance. The root path cost is zero if the bridge is the
root bridge for that instance.
Designated Bridge Bridge Identifier of the bridge with the Designated Port.
Designated Port Port on the Designated Bridge that offers the lowest cost to the LAN.
Identifier
Loop Inconsistent The current loop inconsistent state of this port in this MST instance. When in loop inconsistent state,
State the port has failed to receive BPDUs while configured with loop guard enabled. Loop inconsistent
state maintains the port in a blocking state until a subsequent BPDU is received.
Transitions Into The number of times this interface has transitioned into loop inconsistent state.
Loop Inconsistent
State
Transitions Out of The number of times this interface has transitioned out of loop inconsistent state.
Loop Inconsistent
State
If you specify 0 (defined as the default CIST ID) as the mstid, this command displays the
settings and parameters for a specific switch port within the common and internal spanning
tree. The unit/slot/port is the desired switch port. In this case, the following are
displayed.
Term Definition
Port Identifier The port identifier for this port within the CST.
Port Priority The priority of the port within the CST.
Port Forwarding The forwarding state of the port within the CST.
