Configuring Spanning Tree Algorithm

67

Configuring STA settings for interfaces

Use this procedure to configure Spanning Tree Protocol (STP) attributes
for specific interfaces. In this procedure, the term interfaces refers to both
ports and trunks.

You can use a different priority or path cost for ports of the same media
type to indicate the preferred path, a link type to indicate a point-to-point
connection or shared-media connection, and an edge port to indicate if the
attached device can support fast-forwarding.

Procedure steps

Step

Action

1

From the main menu, choose Applications > Spanning Tree > STA
> Port Configuration or choose Applications > Spanning Tree
> STA > Trunk Configuration.

2

Modify the required attributes.

3

Click Submit.

—End—

Variable definitions

Variable

Value

Port

The port number.

Spanning Tree

Select to enable STA on this interface. (Default: Enabled)

STA State

Indicates the current state of this port within the Spanning Tree
Protocol:

•

Discarding—Port receives STA configuration messages, but
does not forward packets.

•

Learning—Port has transmitted configuration messages for an
interval set by the Forward Delay parameter without receiving
contradictory information. Port address table is cleared and
the port begins learning addresses.

•

Forwarding—Port forwards packets and continues learning
addresses.
