Configuring the Access Server for the First Time

Configuring the Access Server for the First Time

This chapter provides a product overview and describes how to power on the access server to configure it using the prompt-driven setup script.

The following sections are included:

If you prefer to configure the access server manually, proceed to the next chapter "Cisco IOS Software Survival Skills" to familiarize yourself with the command line interface and then proceed to the following chapter, "Configuring the Access Server Manually" for step-by-step instructions.

Note This document assumes you have already connected the cables to the access server in accordance with the instructions and procedures provided in the quick reference guide or hardware installation guide.

Cisco AS5200 Overview

The Cisco AS5200 universal access server is a versatile data communications platform that provides the functions of an access server, a router, and digital modems in a single modular chassis. The Cisco AS5200 is intended for Internet service providers (ISPs), telecommunications carriers, and other providers that offer managed Internet connections, and also small- to medium-size sites that provide both digital and analog access to users on an enterprise network.

The Cisco AS5200 receives and routes both analog and digital calls on the same chassis simultaneously. By doing so, it provides you with a clear, simple, and easy migration path from today's predominantly analog dial-in services to tomorrow's digital dial-in services. The access server enables dial-in clients to make remote asynchronous and ISDN connections to the access server.

To configure remote services, you must configure three interrelated interfaces on the access server. The loopback interface makes the network appear as if the dial-in users exist on one Ethernet segment. The loopback interface has the following four types of neighboring interfaces used for dial-in operations: ISDN interface, dialer interface, group asynchronous interface, and asynchronous interface. Figure 1-1 shows an internal view of the components used to process incoming ISDN and analog calls on an access server.


Figure 1-1: Internal View of Access Server Call Processing Components



All dial-in users exist on one dial-in subnet. Remote asynchronous users dial in through the group asynchronous interface to the access server. Remote ISDN users dial in through the ISDN dialer interface to the access server. Figure 1-2 shows an external view of how remote users dial in to the access server.

Using the Setup Script

The setup script has been updated in Cisco IOS Release 11.3(2)T to reflect the options available for CAS options. In addition, once you select the number of controllers to be used for ISDN PRI, the system automatically configures all the selected controllers for ISDN PRI.

Note Instructions for running the setup script for systems containing Cisco IOS Release 11.2 software are contained in Appendix C, "Using the Setup Script on Cisco IOS Release 11.2."

Getting Started

Before you turn on the access server and begin to use the setup script in the System Configuration dialog, make sure you have already connected the cables to the access server and configured your PC terminal emulation program for 9600 baud, 8 data bits, no parity, and 2 stop bits. All configuration will be performed from your PC terminal emulation program window.

The prompts and resulting messages vary depending on your responses. For most configurations, you can press Return to accept the default entries displayed in square ([]) brackets.

Note Information that you enter is in this boldface font. Also note that if you make a mistake during the configuration, you can exit and run the System Configuration dialog again. Press Ctrl-c, and then type setup at the enable prompt (5200#).

To use the setup script take the following steps:

Step 1 Power ON the access server. The power switch is on the rear panel, at the upper right corner near the power cord.


Figure 1-3: Power Switch Location



Messages will begin to appear in your terminal emulation program window.

 
Caution Do not press any keys on the keyboard until the messages stop. Any keys pressed during this time will be interpreted as the first command typed when the messages stop, which might cause you to power cycle the access server and start over. It will take a few minutes for the messages to stop.

The messages look similar to the following:

Note The displayed messages depend on the Cisco IOS software release and feature set you selected. The screen displays in this section are for reference only and might not exactly reflect the messages on your console.

Step 2 When the following message appears, press Return to accept the default entry (yes) in square brackets:

Step 3 When the following message appears, press Return to see the current interface summary:

Interface IP-Address OK? Method Status Protocol Ethernet0 unassigned NO unset up up Serial0 unassigned NO unset down down Serial1 unassigned NO unset down down

Step 4 Enter a host name for the access server:

Step 5 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration:

Step 6 Enter an enable password. This password is not encrypted (less secure) and can be seen when viewing the configuration:

Step 7 Enter the virtual terminal password, which is used for remote console access:

Step 8 Respond to the following prompts as appropriate for your network:

Step 9 Configure the asynchronous serial lines for the integrated modems or terminal adapters on the modules installed in the access server:

Note We recommend that you do not change this speed for modems. However, for V.110 terminal adapters, we recommend that the speed not go above 19200.
Note If your asynchronous interfaces will be using the same basic configuration parameters, we recommend that you group them so that they can be configured as a group. Otherwise, you will need to configure each interface separately.
Note Make sure the starting and ending addresses of the IP pool are in the same subnet.
Note During this next example we create a user called test. This is just to demonstrate how to create a user. You can substitute any other name you want instead of test.

Step 10 Configure the Ethernet 0 interface:

Step 11 Configure the Serial 0 interface:

Step 12 Configure the Serial 1 interface:

Note If your access server is using a T1/PRI card, continue with the section "Continuing the Setup Script for T1/PRI Cards" and if your access server is using a E1/PRI card, continue with the section "Continuing the Setup Script for E1/PRI Cards".
