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.
