Introduction
This document describes the procedure for recovering an enable password or replacing enable-secret passwords on Cisco 801, 802, 803, 804, 805, 811, and 813 Series Routers. These passwords are used to protect access to privileged EXEC and configuration modes. The enable password can be recovered because it is displayed in plain text in the configutaion file. The enable-secret password is encrypted in the configuration file and therefore can only be replaced with a new password.

Step-by-Step Procedure
Use the following procedure to perform password recovery on the 8xx Series Routers.
You may encounter booting problems with the Cisco 801, 802, 803, 804, 805, 811 and 813 Series Routers. Cisco 801-805, 811, and 813 routers boot into TinyROM at power-up or after saving any configuration from the console port using Cisco IOSЮ Software Release 12.1(3) and later. For details of the affected unit serial number and the procedure to solve the booting problem, see Field Notice: Cisco 801-805 and Cisco 811 and 813 Boots into TinyROM.
Note: To recover a password on Cisco 806, 826, 827, 828, 831, or 837 Series Routers, refer to Password Recovery Procedure for the Cisco 806, 827, and 837 Series Routers.
Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal settings:
9600 baud rate
No parity
8 data bits
1 stop bitThe required console cable specifications are described in Cabling Guide for Console and AUX Ports.
Use the power switch to turn the router off and then turn it back on.
Press Break on the terminal keyboard within 60 seconds of the power-up to put the router into ROMMON.
If the break sequence doesnt work, see Possible Key Combinations for Break Sequence During Password Recovery for other key combinations.
Type set at the boot# prompt and record the current value of the configuration register (set by the “ios-conf” variable):
boot# set
set baud =9600
set data-bits =8
set parity =none
set stop-bits =1
set console-flags =0

set netmask =255.255.252.0
set gate-ip =10.200.40.1
set pkt-timeout =8
set tftp-timeout =16
set boot-action =flash
set file-name =”c800-nsy6-mw.122-10b.bin”
