Use this procedure to view MSTI Port information.
The following table outlines the parameters of the MSTI Port tab.
Variable | Value |
---|---|
Port | Denotes the port number. |
BridgeInstance | The number of times a Spanning Tree instance was deleted. A Trap is generated when this event occurs. |
State | Indicates the current state of the port as defined by the Multiple Spanning Tree Protocol. The state of a port can be Forwarding or Discarding (Blocking). |
ForcePortState | Signifies the current state of the port which can be changed to either Disabled or Enabled for the specific Spanning Tree instance. |
PathCost | Specifies the contribution of this port to the cost of paths towards the MSTI Root which includes this port. |
Priority | Indicates the four most significant bits of the Port Identifier for a given Spanning Tree instance. This value can be modified independently for each Spanning Tree instance supported by the Bridge. The values set for Port Priority must be in steps of 16. |
DesignatedRoot | Specifies the unique Bridge Identifier of the bridge recorded as the MSTI Regional Root in the configuration BPDUs that are transmitted. |
DesignatedBridge | Identifies the unique Bridge Identifier of the bridge which this port considers to be the Designated Bridge for the port segment. |
DesignatedPort | Identifies the Port identifier of the port on the Designated Bridge for this port segment. |
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 the specific instance. This is set to true only when the port is operationally up in the interface level and Protocol level for the specific instance. This is set to false at all other times. |
