Lab 1: Password Recovery-Part I

Lab 1: Password Recovery ”Part I

Practical Scenario

You might need to perform password recovery on a router at many times. To model and set up your lab for practical studies, you need at least three routers. Most of the equipment has a high probability of being used. This equipment might require password recovery for privileged-level access. Sometimes, customers forget passwords. In either case, you need to perform password recovery.

Lab Exercise

You received a stack of routers that you can use to model complex networks. Because this equipment is used, it has an existing configuration stored on NVRAM that is password-protected. You are tasked to archive and then erase the current router configuration.

Lab Objectives

• Examine the original configuration of the router.

• Erase the configuration. The router should have no configuration, and, when it boots, it should come up in setup mode.

Equipment Needed

• One Cisco router.

• One Cisco configuration kit (one rolled cable and appropriate head-shell to connect to the PC/laptop's COM port).

• One PC or laptop with terminal-emulation software.

• All labs from this point on require a PC or laptop with the standard configuration kit and terminal-emulation software. This is the only lab in which this basic configuration equipment is mentioned.

Physical Layout and Prestaging

The router used must have some previous configuration and an enable password set.
