Enabling and Dis- abling STP

Having many bridges creates the potential for network loops. A loop presents conflicting information about the segment on which a specific address is located and forces the bridge to forward all data.

When configuring the IAD as a router (Chapter 4, Router Configuration on page 96), you must disable STP both globally and by port.

NOTE When you enable STP, the IAD reconfigures the bridge network to transfer data along an optimum route to its destination.

Enabling or Disabling STP Globally

To enable or disable STP globally:

1.On the Bridge Configuration menu, type T to select Enable/Disable Spanning Tree Globally.

The IAD displays the status of bridging, and a prompt:

Spanning Tree is Globally DISABLED Enter E to Enable, D to Disable:

Type E to enable spanning tree globally, or D to disable it globally.

2.The IAD saves, then displays the Bridge Configuration menu.

3.Continue with other tasks, or press Escape to return to the Main menu.

4.Reset the IAD (page 14) when you finish bridge configuration.

Enabling or Disabling STP by Port

To enable or disable STP by port:

1.On the Bridge Configuration menu, type O to select Enable/Disable Spanning Tree by Port.

2.The IAD displays the interfaces available on this IAD, and a prompt:

Available Interfaces:

1.G2237 xDSL

2.10/100BaseT Ethernet

0. (Abort)

Type the number of the port for which you want to enable STP.

3.If more than one interface is configured on the selected port, the IAD displays a list of interfaces:

Port DLCI Encapsulation

1 18 Proprietary Voice DLCI

Type the number of the port.

4.The IAD displays the status of this interface and port, and a prompt:

Spanning tree over T1/E1 Port 1, is currently

DISABLED

Enter E to Enable, D to Disable:

Type E to enable STP on this port, or D to disable it.

5.The IAD saves, then displays the Bridge Configuration menu.

6.Repeat these steps for each port you want to enable or disable STP.

7.Reset the IAD (page 14) when you finish bridge configuration.
