5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Command Mode • Privileged EXEC • User EXEC Display Parameters MST Instance ID Port Identifier Port Priority Port Forwarding State Port Role Auto-Calculate Port Path Cost Port Path Cost Designated Root Root Path Cost Designated Bridge Designated Port Identifier Loop Inconsistent State Transitions Into Loop Inconsistent State Transitions Out of Loop Inconsistent State Existing MST instance ID. Port identifier for the specified port (selected MST instance), comprised of port priority and the interface number of the port. Port priority within the selected MST instance. The port priority is displayed in multiples of 16. Current spanning tree state of this port. Port role values: Root Port, Designated Port, Alternate Port, Backup Port, Master Port or Disabled Port. Indicates if auto calculation is enabled. Displays the path cost of the specified port. The value range is between 1 and 65535. The path cost is typically defined as 1000 ÷ /LAN speed in megabits per second. Designated root identifier for the port. The path cost to reach root bridge. The root path cost is zero if bridge is the root instance. Designated Port bridge identifier. Port on the Designated Bridge offering lowest LAN cost. If loop is in inconsistent state, the port has failed to receive BPDUs while configured with loop guard enabled. Loop inconsistent state places the port in a blocking state until subsequent BPDU is received. The number of times transitioned into a loop inconsistent state. The number of times transitioned out of loop inconsistent state. If 0 (defined as the default CIST ID) is specified as the mstid, the command displays the settings and parameters for a specific switch port within the common and internal spanning tree. The following display:. Port Identifier Port Priority Port Forwarding State Port Role Auto-Calculate Port Path Cost Port Path Cost Auto-Calculate External Port Path Cost Port identifier within the CST. Priority within the CST. Forwarding state within the CST. Role of the specified interface within the CST. Indicates if auto calculation is enabled or not (disabled). Configured path cost for the specified interface. Indicates whether auto calculation for external port path cost is enabled. 333
