External Port
Path Cost
The cost to get to the root bridge of the CIST across the boundary of the region. This
means that if 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
Identifier
Port on the Designated Bridge that offers the lowest cost to the LAN.
Topology
Change
Acknowledgem
ent
Value of flag in next Configuration Bridge Protocol Data Unit (BPDU) transmission
indicating if a 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 Status
Derived value indicating if this port is part of a point to point link.
CST Regional
Root
The regional root identifier in use for this port.
CST Internal
Root Path Cost
The internal root path cost to the LAN by the designated external port.
Loop
Inconsistent
State
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.
Transitions Into
Loop
Inconsistent
State
The number of times this interface has transitioned into loop inconsistent state.
Transitions Out
of Loop
Inconsistent
State
The number of times this interface has transitioned out of loop inconsistent state.
