Term Definition
Port Role The role of the specified interface within the CST.
Auto-Calculate Port Indicates whether auto calculation for port path cost is enabled or not (disabled).
Path Cost
Port Path Cost The configured path cost for the specified interface.
Auto-Calculate Indicates whether auto calculation for external port path cost is enabled.
External Port Path
Cost
External Port Path The cost to get to the root bridge of the CIST across the boundary of the region. This means that if
Cost the port is a boundary port for an MSTP region, then the external path cost is used.
Designated Root Identifier of the designated root for this port within the CST.
Root Path Cost The root path cost to the LAN by the port.
Designated Bridge The bridge containing the designated port.
Designated Port Port on the Designated Bridge that offers the lowest cost to the LAN.
Identifier
Topology Change Value of flag in next Configuration Bridge Protocol Data Unit (BPDU) transmission indicating if a
Acknowledgement topology change is in progress for this port.
Hello Time The hello time in use for this port.
Edge Port The configured value indicating if this port is an edge port.
Edge Port Status The derived value of the edge port status. True if operating as an edge port; false otherwise.
Point To Point MAC Derived value indicating if this port is part of a point to point link.
Status
CST Regional Root The regional root identifier in use for this port.
CST Internal Root The internal root path cost to the LAN by the designated external port.
Path Cost
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.
