Configuring Business Policy Switches with Optivity Quick2Config

Chapter 5

Configuring spanning tree

By default, all switch ports are enabled for participation in the Spanning Tree

Protocol (STP).

Read the sections of this is chapter to learn how to use Quick2Config to disable

STP on individual ports or MLT trunks, view STP group and port values, and

customize STP group properties:

• “About the Spanning Tree Protocol,” next

• “Configuring STP ports” on page 55

• “Viewing and configuring STP group properties” on page 58

About the Spanning Tree Protocol

The Spanning Tree Protocol, defined in the IEEE 802.1D standard, determines the

best path between segments of a bridged network. When multiple paths exist, the

spanning tree algorithm configures the network to use only the most efficient path.

If the selected path fails, STP automatically reconfigures the network to make

another path active and sustain network operation.

Configuring STP ports

By default, all switch ports participate in the spanning tree algorithm. For each

switch port or MLT group, you can:

• Change the STP learning state

• Disable STP participation
