cost path to the Internal Root Bridge. (For the CIST instance only) .

Topology Flag :
The current state of the Topology Change Flag of this Bridge instance.

Topology Change Count :
The number of times where the topology change flag has been set (during a one-second
interval).

Topology Change Last :
The time passed since the Topology Flag was last set.
CIST Ports & Aggregations State

Port :
The switch port number of the logical STP port.

Port ID :
The port id as used by the STP protocol. This is the priority part and the logical port index
of the bridge port.

Role :
The current STP port role. The port role can be one of the following
values: AlternatePortBackupPort RootPort DesignatedPort.

State :
The current STP port state. The port state can be one of the following
values: DiscardingLearning Forwarding.

Path Cost :
The current STP port path cost. This will either be a value computed from the Auto setting,
or any explicitly configured value.

Edge :
The current STP port (operational) Edge Flag. An Edge Port is a switch port to which no
Bridges are attached. The flag may be automatically computed or explicitly configured.
Each Edge Port transits directly to the Forwarding Port State, since there is no possibility of
it participating in a loop.

Point-to-Point :
The current STP port point-to-point flag. A point-to-point port connects to a non-shared
LAN media. The flag may be automatically computed or explicitly configured. The point-to-
point properties of a port affect how fast it can transit to STP state.

Uptime :
The time since the bridge port was last initialized.
