Use this procedure to display STG port properties.
The following table outlines the parameters of the Ports tab.
Variable | Value |
---|---|
StgId | The spanning tree group ID to which the VLAN belongs. |
Priority | The value of the priority field that is contained in the first (in network byte order) octet of the (2-octet long) Port ID. The other octet of the Port ID is derived from the value of dot1dStpPort. |
State | The current port state as defined by application of the Spanning Tree Protocol. This state controls the action a port takes when it receives a frame. If the bridge detects a port that is malfunctioning, it places that port into the broken state. For ports that are disabled (see EnableStp), this object has a value of Disabled. |
EnableStp | Select True or False to enable or disable STP. |
FastStart | Select True or False to enable or disable FastStart. |
AdminPathCost | The administrative value of the PathCost. This is the value that has been configured by the user, or 0 if no user-configured value exists. If you specify the path cost in the PathCost field, the value in this field is modified as well. |
PathCost | The contribution of this port to the cost of paths toward the spanning tree root, which includes this port. The IEEE 802.1D-1990 standard recommends that the default value of this parameter be in inverse proportion to the speed of the attached LAN. |
DesignatedRoot | The unique Bridge Identifier of the bridge recorded as the Root in the Configuration BPDUs transmitted by the Designated Bridge for the segment to which the port is attached. |
DesignatedCost | The path cost of the Designated Port of the segment connected to this port. This value is compared to the Root Path Cost field in received bridge PDUs. |
DesignatedBridge | The Bridge Identifier of the bridge that this port considers to be the Designated Bridge for this port segment. |
DesignatedPort | The Port Identifier of the port on the Designated Bridge for this port segment. |
ForwardTransitions | The number of times this port has transitioned from the Learning state to the Forwarding state. |
