Term Definition
The ID of the existing MST instance.
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.
The priority for a particular port within the selected MST instance. The port priority is
displayed in multiples of 16.
Current spanning tree state of this port.
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
Indicates whether auto calculation for port path cost is enabled.
Configured value of the Internal Port Path Cost parameter.
The Identifier of the designated root for this port.
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.
Bridge Identifier of the bridge with the Designated Port.
Port on the Designated Bridge that offers the lowest cost to the LAN.
The current loop inconsistent state of this port in this MST instance. When in loop
inconsistent 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.
The number of times this interface has transitioned into loop inconsistent state.
The number of times this interface has transitioned out of loop inconsistent state.
