Use the following procedure to edit an existing STG configuration.

Procedure steps


Step Action

1

From the navigation tree, double-click VLAN.

2

In the VLAN tree, double-click Spanning Tree.

3

In the Spanning Tree tree, double-click STG.

4

On the work area, click the Configuration tab.

5

To select an STG to edit, click the STG ID.

6

In the STG row, double-click the cell in the Priority column.

7

Type a value in the dialog box.

8

In the STG row, double-click the cell in the BridgeMaxAge column.

9

Type a value in the dialog box.

10

In the STG row, double-click the cell in the BridgeHelloTime column.

11

Type a value in the dialog box.

12

In the STG row, double-click the cell in the EnableStp column.

13

Select a value from the list—true to enable STP for the STG, or false to disable STP for the STG.

14

In the STG row, double-click the cell in the TaggedBpduAddress column.

15

Type a value in the dialog box.

Variable Definitions

Use the data in the following table to edit an existing STG.

Variable Value
Id Indicates the identifier for the STG. Values range from 1 to 8. The default STG ID is 1. This is a read-only cell.
BridgeAddress Indicates the MAC address used by a bridge when the bridge must be referred to in a unique fashion. The bridge MAC address can be integrated with the priority value to form a unique bridge identifier that is used in the Spanning Tree Protocol. This is a read-only cell.
NumPorts Indicates the number of ports controlled by this bridging entity. This is a read-only cell.
Protocol
Specification

Version of the spanning tree protocol being run. Values include:

  • decLb100: Indicates the DEC LANbridge 100 Spanning Tree Protocol.
  • ieee8021d: IEEE 802.1d implementations will return this entry. When future versions of the IEEE Spanning Tree Protocol are released that are incompatible with the current version, a new value will be defined.
This is a read-only cell.
Priority Specifies the first two octets of the 8-octet bridge ID. Values range from 0 to 65535.
BridgeMaxAge Specifies the maximum time you want to allow before the specified STG times out, in seconds; the range, measured in hundredths of a second, is 600 (6 seconds) to 4000 (40 seconds).
BridgeHelloTime Specifies the maximum time between hellos, in seconds; the range, measured in hundredths of a second, is 100 (1 second) to 1000 (10 seconds).
BridgeForwardDelay Specifies the maximum delay in forwarding, in seconds; the range, measured in hundredths of a second) is 400 (4 seconds) to 3000 (30 seconds).
EnableStp Enables (true) or disables (false) STP for the STG.
TaggedBpduAddress Specifies the destination MAC address assigned to tagged BPDUs.
TaggedBpduVlanId Specifies the VLAN ID for tagged BPDUs. This value must be unique for each specific STG.
