I have a 2504 router, that is password protected.

How do I reset this, not worried about keeping config data.

Any advice appreciated.

Cheers,
Kristian

Search www.cisco.com for  2500 password reset
and you should find complete instructions (probably involving
a connection to the serial port, a power cycle, sending break
within a few seconds, changing the config register, that sort
of stuff.)

type "password recovery procedure 2503" in the search field of www.cisco.com

Hello,

here you have little copy&paste from Cisco pages...

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 
The required console cable specifications are described in the Cabling 
Guide for RJ-45 Console and AUX Ports(Cisco 1000 Series, 2500 Series, and 
AS5100).

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.

I hope that will help you.

Kind regards,


Piotr Derda

Password-Recovery is similar on nearly all Cisco-Routers (switches
have a different method for Password-Recovery):

Start the router and send a "break-character" to console while the
machine tries to boot. If this operation was successful, you are
now in the boot-monitor. Here, you can set the confuration-register
to the value 0x142 (the method to set this register is different,
depending of the version of the boot-monitor and maybe the type of
the router). When you reboot the machine with this value in the
configuration register, it does *not* load the configuration from
nvram, i.e. you have now a totally unconfigured router (with no
enable password and no enable secret). You can go to "enable mode",
copy the "startup-config" to the "running-config", set a new enable 
password (or enable secret), write the configuration back to NVRAM
and reboot the machine. To restore the original value of the confi-
guration register, you have to send a break to the console while the
machine is booting to get in the boot-monitor, ...

The value of the configuration register is displayed when you type
the (unprivileged) command "show version", but in most cases a value
of 0x2102 should be usable (in case, you missed to write down the
original value *before* setting the config-register to 0x142).
