Configuring a Bridging Service

Configuring a Bridging Service
Frame Relay traffic is automatically bridged for Group 1 in a switch. You can alter this default
through two different commands:
frmodify and cas .
The frmodify 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
frmodify . See Modifying a Port on page
29-22 for more information on the frmodify command.
The cas command provides more control over bridging service configuration. In addition to
naming, enabling and disabling bridging services through cas , you can assign specific virtual
circuits to a bridging service. Follow the steps below to set up a bridging service through the
cas command.
1. Enter the cas command followed the slot number, a slash (/), the port number, and then
the service number for the bridging service:
cas 2/3 3
A screen similar to the following displays:
Slot 1 Port 2 Service 3 Configuration
1) Description ................................................................... = Frame-Relay
{Enter up to 30 characters}
2) Service Type ................................................................. = Bridging
{(T)runking, (R)outing, (B)ridging}
3) Administrative Status .................................................... = Enabled
{(E)nable, (D)isable}
4) VC(s)............................................................................. = 0
5) VLAN Group(s) .............................................................. = 0
6) Frame-Relay Bridging Mode (Applies to Bridging Only).. = Bridge All
{Bridge (a)ll, (E)thernet only}
(save/quit/cancel)
:
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.
1=<bridge service name>
When you are done entering a description, press <Enter> .
3. Specify that this is a bridging service by entering a 2, an equal sign, and a B as follows:
2=B
This specifies that you want to set up a bridging service, as opposed to a Trunking or
Routing service. Press
<Enter> .
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
3=D and press <Enter> .
