MSTP MSTI Port tab parameters

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 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 The unique Bridge Identifier of the bridge recorded as the MSTI Regional Root in the configuration BPDUs that are transmitted.
DesignatedBridge The unique Bridge Identifier of the bridge which this port considers to be the Designated Bridge for the port segment.
ERS5000_62_Help2_DLM-18920342.html# DesignatedPort The Port identifier of the port on the Designated Bridge for this port segment.
DesignatedCost The path cost of the Designated Port of the segment connected to this port.
CurrentPortRole Current Port Role of the port for this spanning tree instance.
EffectivePortState 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.
