Lab 5.2.6a Password Recovery Procedures

This lab demonstrates gaining access to a router with an unknown privileged mode (enable) password. One point to be made here is that anyone with this procedure and access to a console port on a router can change the password and take control of the router. That is why it is of critical importance that routers also have physical security to prevent unauthorized access. Setup a network similar to the one in the previous diagram. Any router that meets the interface requirements may be used. Possible routers include 800, 1600, 1700, 2500, 2600 routers, or a combination.

Background Preparation This lab demonstrates gaining access to a router with an unknown privileged mode enable password. One point to be made here is that anyone with this procedure and access to a console port on a router can change the password and take control of the router. That is why it is of critical importance that routers also have physical security to prevent unauthorized access. Setup a network similar to the one in the previous diagram. Any router that meets the interface requirements may be used. Possible routers include 800 1600 1700 2500 2600 routers or a combination. Refer to the chart at the end of the lab to correctly identify the interface identifiers to be used based on the equipment in the lab. The configuration output used in this lab is produced from 1721 series routers. Any other router used may produce slightly different output. The following steps are intended to be executed on each router unless specifically instructed otherwise. Start a HyperTerminal session as performed in the Establishing a HyperTerminal session lab. Note Configure the hostname and passwords on the router. Have an instructor lab assistant or other student configure a basic configuration with an enable secret password. Perform copy running-config startup-config and reload the router. Note The version of HyperTerminal provided with Windows 95 98 NT and 2000 was developed for Microsoft by Hilgraeve. Some versions may not issue a break sequence as required for the Cisco router password recovery technique.
