Column Meaning
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.
