Forgot Password... how do I reset the Pix 501. 1

[Nytro]

I'm a network administrator and have been working 3 days into my new job. My boss has given me a Cisco PIX 501 ver 4.3 to configure. The problem is that the router's password has been missing for quite a while. I have used a Console Cable utilizing Hyper terminal and can access the Command Line Interface (CLI). I type "enable" and hit the enter button and the "password" prompt displays.

Is their another way to reset the router and or password. I have the " Packaged Service Contract" from Cisco.

Help welcome

I have a similar problem with a CISCO 4000-M router. I cannot get past the password to set it up. No one remembers the blasted thing. HOw do I reset the router so I can give ti a new password?

Try this(I know there is a lot of it):

Introduction
This document describes the password recovery procedure for the following Cisco products:

Cisco 2000 Cisco 4000 Cisco AGS
Cisco 2500 Cisco AccessPro Cisco IGS

Cisco 3000
Cisco 7000 (RP)
Cisco STS-10x


Overview
The "enable" password or the "enable-secret" password is stored in the startup-configuration file in the nonvolatile RAM (NVRAM). The password recovery procedure involves booting the router while ignoring the startup-configuration file in the NVRAM. This can be achieved by setting the 6th bit in the configuration register. The router then boots with the default configuration and all the interfaces in "shutdown" state. Since the default configuration does not have a password, anyone can now enter the enable mode on the router. To get back the original configuration of the router, the startup-configuration file can be copied into the router memory. If you are already in the enable mode, you can either view and or change the "enable" password, but can only change the "enable-secret" password, because it is always encrypted in the show commands. This document details this procedure.

Hardware and Software Versions
The information in this document is based on the following versions:

Cisco IOS Software Release 12.2(10b)

Although a Cisco 2500 Series Router is used as an example in this document, the password recovery procedure presented here applies to all the platforms listed above.

Step-by-Step Procedure
Follow this procedure to recover a lost or forgotten password:

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 bit
No flow control
Note: Password recovery procedures cannot be done using telnet connections.

Using the power switch, turn the router off and then turn it back on.

Send a break sequence from the terminal keyboard within 60 seconds of the power-up to put the router into ROMMON. The break sequence depends on your Operating System/Terminal Emulator. See Standard Break Key Sequence Combinations During Password Recovery for different key combinations.

Type o and press Enter at the > prompt, and record the current value of the configuration register (usually 0x2102, or 0x102):

>o

!--- Shows the configuration register option settings


Configuration register = 0x2102 at last boot
Bit# Configuration register option settings:
15 Diagnostic mode disabled
.......
Type o/r 0x2142 and press Enter at the > prompt to boot from Flash without loading the configuration.

Type i at the > prompt and press Enter.

The router reboots, but ignores its saved configuration.

Type no after each setup question or press Ctrl-C to skip the initial setup procedure.

Type enable at the Router> prompt.

You'll be in enable mode and see the Router# prompt.

Type configure memory or copy startup-config running-config to copy the NVRAM into memory. Do not type write memory or copy running startup-config.

Type write terminal or show running-config.

The show running-config and write terminal commands show the configuration of the router. In this configuration you see under all the interfaces the shutdown command, which means all interfaces are currently shutdown. Also, you can see the passwords either in encrypted or unencrypted format.

Type configure terminal and make the changes.

The prompt is now:

hostname(config)#
Type enable secret <password>.

Issue the no shutdown command on every interface that is used. If you issue a show ip interface brief command after you exit configuration mode, every interface that you want to use should be "up up".

Type config-register 0x2102, or the value you recorded in step 4.

This causes the router to load the Cisco IOS software from the Flash with the configuration from NVRAM at the next reload.

Press Ctrl-z to leave the configuration mode.

The prompt is now:

hostname#
Type write memory or copy running-config startup-config to commit the changes.

Type Reload to restart the router with the Cisco IOS software booting from the Flash.

Thank you for the information "eurobadger" concerning the Pix 501 series router... however the information contained in Cisco's Web-site assumes you have a reset button on the router. The router I'm working with has no reset button.

The password recovery procedures Cisco, has concerning the Pix 501 series router are:

A. with a floppy drive
B. without a floppy drive

I have tried both procedures and had no luck... again the instructions assume you have a reset button on the router. I have downloaded the "nppix.bin" and "rawrite.exe" file for the routers firmware ver. 4.3

I have tried to reset the router by removing the power cable, still no luck.

Please respond "eurobadger"

Thank You

Nytro

Hi Nytro.

I confess I have not done this in a long while & I have no unit to try it on. However the procedure without a floppy drive looks to be what you need. It does not rely on pressing the reset button (even if you had one), but talks about sending a BREAK or ESC to the PIX directly after power-up. This seems to be just like you do with a router.

The snag is that the BREAK or ESC keys may not do the job alone, but need a combination of keys. You probably need <CTRL>_BREAK, but look at:

http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a0080174a34.shtml

for a table of other possibilities depending on the PC and terminal emulator you use.

The right key combination (and pressing it at the right time) should get you to the Monitor> prompt as described.

If that does not get you there it is probably time to call Cisco for help.

Thank you for your quick response "eurobadger"...

I will try this procedure and let you know the outcome.


Thank you for your outstanding support.
