# Configuring STG port properties

Use this procedure to display STG port properties.

## Procedure steps

1. From the navigation tree, double-click Edit.

2. From the Edit tree, double-click Chassis.

3. From the Chassis tree, click Ports.

4. Select the STG tab.

## Variable definitions

The following table outlines the parameters of the Ports tab.

Table 1. Chassis Ports tab parameters
Variable | Value
--- | ---
Port | Specifies the port number.
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.
