Introduction
This document describes how to recover the enable password and the enablesecret passwords. These passwords protect access to privileged EXEC and configuration modes.

Cisco − Password Recovery Procedure for the Cisco 2600 and 2800 Series Routers

Step−by−Step Procedure
Follow these steps in order to recoveryour password: 1. Attach a terminal or PC with terminal emulation to the console port of the router. Use these terminal settings: ♦ 9600 baud rate ♦ No parity ♦ 8 data bits ♦ 1 stop bit ♦ No flow control Refer to these documents for information on how to cable and connect a terminal to the console port or the AUX port: ♦ Cabling Guide for Console and AUX Ports ♦ Connecting a Terminal to the ConsolePort on Catalyst Switches ♦ Connect a Terminal to Catalyst 2948G−L3, 4908G−L3, and 4840G Series Switches 2. If you can access the router, type show version at the prompt, and record the configuration register setting. See Example of Password Recovery Procedure in order to view the output of a show version command Note: The configuration register is usually set to 0x2102 or 0x102. If you can nolonger access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0x2102. 3. Use the power switch in order to turn off the router, and then turn the router back on. Important Notes: ♦ In order to simulate this step on a Cisco 6400, pull out and then plug in the Node Route Processor (NRP) or Node Switch Processor (NSP) card. ♦ Inorder to simulate this step on a Cisco 6x00 with NI−2, pull out and then plug in the NI−2 card. 4. Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMMON. If the break sequence does not work, refer to Standard Break Key Sequence Combinations During Password Recovery for other key combinations. 5. Type confreg 0x2142 at the rommon 1> prompt in orderto boot from Flash. This step bypasses the startup configuration where the passwords are stored. 6. Type reset at the rommon 2> prompt. The router reboots, but ignores the saved configuration. 7. Type no after each setup question, or press Ctrl−C in order to skip the initial setup procedure. 8. Type enable at the Router> prompt. You are in enable mode and should see the Router# prompt. 9. Typeconfigure memory or copy startup−config running−config in order to copy the nonvolatile RAM (NVRAM) into memory.
