The 

 command allows you to change the default Bridging Group from Group 1 to 

another Group or to turn off bridging completely. This command configures bridging on a 
port-by-port basis, but does not configure bridging on a virtual circuit basis—all virtual 
circuits may also be assigned to the Group specified in 

. See Modifying a Port on page 

 command.

The 

 command provides more control over bridging service configuration. In addition to 

naming, enabling and disabling bridging services through 

, you can assign specific virtual 

circuits to a bridging service. Follow the steps below to set up a bridging service through the 

 command.

1. Enter the 

 command followed the slot number, a slash (/), the port number, and then 

the service number for the bridging service:

A screen similar to the following displays:

You make changes to the options in this screen at the colon prompt (:). You make 
changes by entering the line number for the option you want to change, an equal sign 
(=), and then the value for the new parameter. 

2. Enter a description of this bridging service by entering 1, an equal sign (=), and then a 

description for this service. Your description can be up to 30 characters long.

This specifies that you want to set up a bridging service, as opposed to a Trunking or 
Routing service. Press 

.

4. By default, the bridging service is Enabled. This means that as soon as you are done 

configuring the service, it will begin bridging Frame Relay traffic. If you would like to 
disable this bridging service now and enable it later, enter 

 and press 

.
