Using CFGEDIT, we will guide you through the steps to configure the CyberSWITCH for a simple remote bridge network. We will execute these steps in the same order as they appear in the configuration menus.

Start the CFGEDIT configuration utility. Type the following command at the system prompt: cfgedit <return>

The following Main Menu will then be displayed:

Main Menu:

1)Physical Resources



4)Save Changes

Select function from above or <RET> to exit:


We start with configuring the Physical Resource information. Press 1 at the Main Menu to display the Physical Resource Configuration Menu:

Physical Resource Menu:


2)Data Lines


4)ISDN Subaddress

Select function from above or <RET> for previous menu:

You may only configure the switch type. The rest of the resource information may only be displayed.

We will next add the line information. Press 2 at the Physical Resources Menu and press 1 to add a line. First, you will be prompted for the line name. You will then be asked to select which slot and port you wish to use. We will use LINE1 as the line name, and slot 1, port 1 as the slot and port combination:

LINE NAME or press <RET> for previous menu: LINE1

Currently available Ports:


Resource Type

Available Ports

Switch Type







1, 2, 3, 4


Slot number from above? 1

Port number from Slot 1? 1

You will then be prompted for the line interface type. For our example, we will be using point-to-point lines. Press 1 as shown below to select this line type.

Bridging and Routing Information




Select Option [default = POINT_TO_POINT] or press <RET> for previous menu: 1

The next item that you need to configure is the Data Link for the line. Depending on the switch type, there may be more than one Data Link per line. In our example, we use one Data Link with Automatic TEI Negotiation:

Current DATA LINK Configuration for this line:

id TEI


There are currently no Data Links configured for this line.

Enter (1) to Add or press <RET> for previous menu: 1

Automatic TEI Negotiation (Y or N) [default = Y]? Y

Current Data Link Configuration for this line:







(1) Add, (2) Change, (3) Delete a DATA LINK or press <RET> for previous menu? <RET>

After entering the above information, press <return> to display the line menu. Because there are four lines in this example, the steps for adding a line should be repeated for lines 2, 3, and 4. After all lines have been added, press <return> twice to return to the Main Menu.


The default configuration for the CyberSWITCH is bridging disabled and IP routing enabled. For reasons we provide below, we want both bridging and IP routing enabled. Under the Option Menu, select the bridging option and follow the instructions to enable bridging.

This network is a bridged network, but we are going to configure an IP option (the IP host operating mode) so that we may use an IP application (such as Telnet, TFTP, or SNMP) to manage the CyberSWITCH. Refer to the graphic below for clarification.

Telnet Client


CSX1200 "B"

IP Host Interface

The network illustrated above is a bridged network. Each system, SITE1 and SITE2 have been configured with all the necessary bridging information. SITE1 and SITE2 have also been configured in the IP host operating mode, and each have an IP host interface. This will allow each system to be managed remotely by the PC using Telnet client software (once the initial configuration has been completed).

Note that the IP address associated with each system is on the same LAN as the PC. This does not have to be the case. As long as the PC has access to the systems through their IP addresses, it can manage the systems using Telnet (or one of the other IP applications).

The steps below describe the configuration steps needed for the above example:

To enable the IP Host Operating Mode:

1.Select IP Operating Mode from the IP configuration menu.

2.Select IP host operating mode.

Note: The IP operating mode can not be set to host unless bridging is enabled.

3.When you select the IP host operating mode, an abbreviated IP configuration will be displayed (similar to the following):

IP Menu:

1)IP Routing (Enable/Disable)

2)IP Operating Mode

3)IP Interfaces

4)IP Static Routes

5)RIP (Enable/Disable)

6)IP Static ARP Table Entries

7)Isolated Mode (Enable/Disable)

8)Static Route Lookup via RADIUS (Enable/Disable)

9)IP Address Pool

10)IP Filter Information

11)DHCP Information
