show spanning-tree mst port summary
This command displays the settings of one or all ports within the specified multiple spanning tree
instance. The parameter
<mstid>
indicates a particular MST instance. The parameter {
<unit/
slot/port
>
| all}
indicates the desired switch port or all ports.
If you specify 0 (defined as the default CIST ID) as the
<mstid>
, the status summary displays for
one or all ports within the common and internal spanning tree.
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

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.
