Step-by-Step Procedure
Follow these steps in order to recover your password:
1. Attach a terminal or PC with terminal emulation to the console port of the router.
Use these terminal settings:
o 9600 baud rate
o No parity
o 8 data bits
o 1 stop bit
o 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:
o Cabling Guide for Console and AUX Ports
o Connecting a Terminal to the Console Port on Catalyst Switches
o 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 0×2102 or 0×102. If you can no longer access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0×2102.
3. Use the power switch in order to turn off the router, and then turn the router back on.
Important Notes:
o 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.
o In order to simulate this step on a Cisco 6×00 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 0×2142 at the rommon 1> prompt in order to 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. Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.
Important: Do not type copy running-config startup-config or write. These commands erase your startup configuration.
10. Type show running-config.
The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
11. Type configure terminal.
The hostname(config)# prompt appears.
12. Type enable secret in order to change the enable secret password. For example:
13. hostname(config)#enable secret cisco
14.
15. Issue the no shutdown command on every interface that you use.
If you issue a show ip interface brief command, every interface that you want to use should display up up.
16. Type config-register . Where configuration_register_setting is either the value you recorded in step 2 or 0×2102 . For example:
17. hostname(config)#config-register 0×2102
18.
19. Press Ctrl-z or end in order to leave the configuration mode.
The hostname# prompt appears.
20. Type write memory or copy running-config startup-config in order to commit the changes.

ProCurve – Firmware Upgrade
1. Download the latest firmware version for your switch :

http://www.hp.com/rnd/software/switches.htm

2. Unpack the zip file into a simple directory i.e. c:\temp or c:\tftp
3. Download and unpack the latest version of Tftp32.
Latest version can be downloaded from: http://tftpd32.jounin.net/
4. Start the tftpd32.exe file – click browse and select the folder created in step 2

5. Create a telnet session to your switch (Start > run > telnet )
and log in to the unit using your password and username if required.
6. In the CLI session type menu and hit the Enter key – this should take you to
the menu interface of the switch. (Should you be asked if you want to save
the current configuration please select yes)

7. Select the option Download OS and hit the enter key.

8. Select TFTP as Method (change by hitting the space key). Fill in the IP
address of your client (can be seen in Tftpd32 > Server interface) and the full
filename of the firmware file (located in the directory created in step 2). It
should look something like the image below.

9. When all three fields are filled in correctly hit the enter key and in the action
list select eXecute. This will initiate the download of the firmware to the
switch which usually takes a few seconds.
When the download is complete the switch will reboot and automatically load
the new firmware – your telnet session will time out.
10. To confirm that the upgrade has gone through correctly start a new telnet
session and in the CLI type show system and hit enter. This will give
information about the firmware currently running.
