Lab 6: Configuring Remote Access to the Lab ”Part I

Practical Scenario

Attaching a modem to an auxiliary port or an asynchronous line provides a useful out-of- band method of management for routers and switches. You can provide a complete "configuration safety net" for your network with the placement of an access server at a central site. The access server would connect the console ports of all the routers at the central site; when combined with an analog modem, this provides a reliable method of access to your network.

Lab Exercise

This is the final lab of Chapter 1, and it serves as the springboard for all the other labs in this text. From this point on, you use this access server to configure the routers in the lab. To further enhance access to the lab, you add a modem to the last asynchronous port on the access server. This device serves as a key device in modeling some of the most complex internetworks known today. Therefore, the name Skynet is used to give the access server and models some character.

Lab Objectives

• Refer to Figure 1-18, and cable the access server as shown.

  Figure 1-18. Lab 6: Physical Layout

  

• Configure a reverse Telnet session from the access server to all the routers attached to Octal cable. Use an IP host-name table to ease the use of reverse Telnet sessions.

• Configure the modem on the asynchronous line to accept an analog dialup session into the router.

Equipment Needed

• One Cisco 2509-2511, Cisco 2600, or Cisco 3600 for the access server, along with the asynchronous module and octal cable.

• One to five other routers. (Only one is needed to complete this lab.)

• One analog modem, modem head-shell, and Cisco rolled cable.

Physical Layout and Prestaging

Asynchronous connections should be connected as noted in Figure 1-18.
