Lab 4: Configuring an Access Server ”Part I

Practical Scenario

An access server provides out-of- band management to an entire stack of routers. This can provide an easy method of configuring access to a variety of Cisco routers and switches from a single device.

Lab Exercise

In this practical exercise, you configure an access server for reverse Telnet access to all the routers and switches in your rack. This enables you to configure multiple routers and switches without having to manually switch the console cable between them.

Lab Objectives

• Add a loopback interface to the access router. This address should be 201.201.1.1.

• Configure an IP host table so that the following exists:

  - Hostname r1 performs a reverse Telnet to the first router in your stack.

  - Hostname r2 performs a reverse Telnet to the second router in your stack, and so on.

• Minimize contention for the asynchronous lines.

• Prevent router sessions from timing out on all remote routers.

Equipment Needed

• Two Cisco routers and one Cisco 2509 “2511, or a 2600 series router with an asynchronous module for the access server. The access server also requires the octal cable.

Physical Layout and Prestaging

• One workstation connected by its COM port to a Cisco 2509 “2511, through Cisco black or light-blue rolled cable is required.

• Connect the octal cable labeled 1 to an R1 or the first router's console port. Repeat this process for every router or switch in lab.
