MSTI Port Field Descriptions
Use the data in the following procedure to use the MSTI Port tab.
|
Name |
Description |
|---|---|
|
Port |
Specifies the port number of the port for which this entry contains spanning tree information. |
|
Instance |
Specifies the spanning tree instance to which the information belongs. |
|
PathCost |
Specifies the contribution of this port to the path cost of paths towards the MSTI root that includes this port. |
|
Priority |
Specifies the four most significant bits of the port identifier for a given spanning tree instance can be modified independently for each spanning tree instance supported by the bridge. The values configured for port priority must be in steps of 16. The default is 128. |
|
DesignatedRoot |
Specifies the unique bridge identifier of the bridge recorded as the MSTI regional root in the configuration BPDUs transmitted. |
|
DesignatedBridge |
Specifies the unique bridge identifier of the bridge that this port considers to be the designated bridge for the port segment. |
|
DesignatedPort |
Specifies the port identifier of the port on the designated bridge for this port segment. |
|
State |
Specifies the current state of the port, as defined by the MSTP. A port which is in forwarding state in one instance can be in discarding (blocking) state in another instance. |
|
ForcePortState |
Specifies the current state of the port, that is changed to either disabled or enabled for the specific spanning tree instance. |
|
DesignatedCost |
Specifies the path cost of the designated port of the segment connected to this port. |
|
CurrentPortRole |
Specifies the current port role of the port for this spanning tree instance. |
|
EffectivePortState |
Specifies the effective operational state of the port for a specific instance. This is configured to true if the port is operationally up at the interface and protocol levels for the specific instance. This is configured to false at all other times. |
