Term Definition
External Port The cost to get to the root bridge of the CIST across the boundary of the region. This
Path Cost
means that if the port is a boundary port for an MSTP region, then the external path cost
is used.
Designated Identifier of the designated root for this port within the CST.
Root
Root Path Cost The root path cost to the LAN by the port.
Designated The bridge containing the designated port.
Bridge
Designated Port Port on the Designated Bridge that offers the lowest cost to the LAN.
Identifier
Topology Value of flag in next Configuration Bridge Protocol Data Unit (BPDU) transmission
Change
indicating if a topology change is in progress for this port.
Acknowledgem
ent
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 The derived value of the edge port status. True if operating as an edge port; false
Status
otherwise.
Point To Point Derived value indicating if this port is part of a point to point link.
MAC Status
CST Regional The regional root identifier in use for this port.
Root
CST Internal The internal root path cost to the LAN by the designated external port.
Root Path Cost
Loop The current loop inconsistent state of this port in this MST instance. When in loop
Inconsistent
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 The number of times this interface has transitioned into loop inconsistent state.
