Password Recovery Procedure
for the Catalyst 5000 ATM LANE Module
Description
This document describes the password recovery procedure for the Cisco Catalyst 5000 ATM LAN emulation (LANE) module
(WS-X5153/5154/5155/5156/5157/5158/5166).
Step-by-Step Procedure
In order to recover a password, you must download a recovery image onto the ATM module that will erase the contents of nonvolatile RAM (NVRAM).
1. Before you start, make sure you have the ATM module recovery image and the original or latest ATM module image. To get this image, establish an FTP session to ftp.cisco.com and log in as c5k_atmp. Use your email address as the password. Enter the get atm_911.cbi command.
2. Download the ATM module recovery image on the Catalyst 5000 supervisor console by typing:
download host atm_911.cbi atm mod_num
3. Wait for the module online message. At this time, the password is disabled and the NVRAM on the ATM module is erased. Reboot the Catalyst 5000.
If you wish to save your original configuration without the password, continue with step 4 below. Otherwise, to enter a new configuration, skip to step 5.
4. Enter the session ATM slot # command. Then, on the ATM module, type:
enable (you will not be prompted for a password)
write memory
exit
This will save your configuration, but without the enable password.
5. To enter a new configuration, download the original ATM image by typing:
download filename
6. Once you receive the module online message, you may session to the ATM module and enable without a password.

Password Recovery Procedure for the Cisco Catalyst 6000 MSFC
Description
This document describes the password recovery procedure for the Cisco Catalyst 6000 Multilayer Switch Feature Card (MSFC).
Step-by-Step Procedure
1. Attach a terminal or PC with terminal emulation to the console port of the switch.
Use the following terminal settings: 9600 baud, no parity, 8 data bits, 1 stop bit
2. Type show module to determine the MSFC card on which to do password recovery.
The MSFC module is in slot 15 or 16.
3. Reset the MSFC module you want to do password recovery on.
Use the reset command to do this.
4. Wait 5 seconds and then connect to the MSFC console using the switch console command.
5. After seeing the message "Connected to Router", issue a break sequence.
The break key is a unique sequence that will break the MSFC into rommon. If this does not work, please refer to the
break sequence page
.
The MSFC will boot to a rommon> prompt.
6. Type confreg 0x42 at the rommon> prompt to configure the MSFC to boot without its configuration.
7. Display the current software in bootflash by issuing the dir bootflash: command and record the current software version.
8. Boot the system with the boot bootflash: command.
NOTE : Do NOT boot the system using the c6msfc-boot image. Doing so will result in loss of configuration after the password recovery process.
9. After the system boots, answer "No" to all the set-up questions or press Ctrl-C to skip the initial set-up procedure.
10. Type enable at the Router> prompt. This will put you in enable mode and you will see the Router# prompt.
11. Type config mem or copy startup-config running-config to copy the nonvolatile RAM (NVRAM) into memory.
This is a crucial step. DO NOT save the configuration (do not use write term or copy running-config startup-config)
12. Type write terminal or show running-config.
At this point, you should see the full configuration with the unknown enable password or enable secret. All other interfaces are shut down.
13. Type configure terminal to make the necessary changes.
The prompt is now hostname(config)#
14. Type enable secret . Replace with your password.
15. Use the no shutdown command on interfaces that are being used.
If you use the show ip interface brief command, every interface that you want to use should be up.
16. Type config-register 0x2102
17. Press Ctrl-Z to leave the configuration mode. The prompt is now hostname#
18. Type write memory or copy running-config startup-config to commit the changes.

5.Cisco LANE-MPOA 口令恢复
Password Recovery Procedure
for LANE/MPOA Modules
Description
This document describes the password recovery procedure for the following Local Area Network Emulation (LANE) and Multiprotocol over Asynchronous Transfer Mode (MPOA) modules:
WS-X5161
WS-X5162
WS-X5165
WS-X5167
WS-X5168
Note: Before you can use this method to erase the Nonvolatile Random Access Memory (NVRAM) configuration, you must have a separate console connected to the LANE/MPOA board. Carrying out this password recovery procedure via a session on supervisor will not work since it produces displays only after Cisco IOS® Software comes up (whereas you need to access in the programmable read-only memory (ROM) at boot time itself).
Step-by-Step Procedure
1. Issue the reset command from supervisor for the LANE/MPOA board. A programmable ROM boot message appears on the console.
2. When you see the following line, hit the ESC key:
Hit ESC key within 3 seconds to enter SOFT-JUMPER config menu.
This displays the Soft Jumper Configuration menu, which displays or modifies the soft jumpers of the board. The IOS software uses these jumpers to determine the mode and other debug functionalities.
3. Choose option 2, the Modify Jumper Configuration menu item. You do not need to press Enter when selecting from this menu.
This option displays information for every jumper and asks if you want to change the jumper configuration.
4. Answer n to all questions until you see the following line :
DMON jumper .................Disabled. Want to change (y/n/q/e/d)?
5. Type e to enable debug monitor mode.
You can now see that the debug monitor jumper is ENABLED.
6. Quit the menu by typing q.
The programmable ROM boot continues with the startup.
7. Reset the LANE/MPOA board again from the supervisor. The LANE/MPOA console shows that the programmable read-only memory goes into debug monitor mode, displaying DMON> as a prompt.
8. Enter the debug monitor mwl command (multiple write of long words). You do not need to press Enter.
The monitor asks for the start address, count and data. Enter the following data (again, you do not need to press Enter):
DMON:> mwlStart Addr? 20000000 Count? 0006ffff Data? ffffffff
This erases the NVRAM configurations.
Note: The count value should not exceed 6ffff. If you type in the wrong value, you can quit this mwl command at any moment by typing q. Please also note that the Backspace key does not work on this monitor.
9. Type q or f to debug the monitor. This takes you through the usual boot programmable read-only memory path.
10. When you see the following message, quickly hit the ESC key:
Hit ESC key within 3 seconds to enter SOFT-JUMPER config menu.
This displays the Soft Jumper Configuration menu.
11. Choose option 2 to disable the debug monitor jumper.
As in step 4 above, keep entering n until you see the debug monitor jumper information line.
12. Type d to disable the jumper.
13. Type q to quit the menu. The LANE/MPOA board boots to the Cisco IOS prompt as usual but it does not have a configuration in NVRAM. You can now reconfigure it as needed.
6.cisco pix
Password Recovery Procedure
for PIX
Description
This document describes how to recover a PIX password for PIX software releases through 5.1.
The PIX Password Lockout Utility is based on the PIX software release you are running.
In addition to the required files listed in the next section, you will need the following items to follow the password recovery procedure:
A PC
A working serial terminal or terminal emulator
Approximately 10 minutes of PIX and network downtime
Required Files
Note: If you are a registered user and have logged in, you can download the files here. If you are not a registered user, please open a case with the Technical Assistance Center (TAC) to obtain the files.
The PIX Password Lockout Utility, which includes the following files:
rawrite.exe>
One of the following files:
nppix.bin (4.3 and earlier releases)
np44.bin (4.4 release)
np50.bin (5.0 release)
np51.bin (5.1 release)
Step-by-Step Procedure
PIX with a Floppy Drive
1. Execute the rawrite.exe file on your PC and answer the questions on the screen.
2. Install a serial terminal or a PC with terminal emulation software on the PIX console port.
3. Verify that you have a connection with the PIX, and that characters are going from the terminal to the PIX, and from the PIX to the terminal.
Note: Because you are locked out, you will see only a password prompt.
4. Insert the PIX Password Lockout Utility disk into the floppy drive of the PIX.
5. Push the Reset button on the front of the PIX. The PIX will reboot from the floppy and print the message below:
Erasing Flash Password. Please eject diskette and reboot.
6. Eject the disk and press the Reset button. You will now be able to log in without a password. When you are prompted for a password, press Return.
7. Create a password with the passwd command, and save your configuration.
PIX without a Floppy Drive
1. Install a serial terminal or a PC with terminal emulation software on the PIX console port.
2. Verify that you have a connection with the PIX, and that characters are going from the terminal to the PIX, and from the PIX to the terminal.
Note: Because you are locked out, you will see only a password prompt.
3. Immediately after you power on the PIX Firewall and the startup messages appear, send a BREAK character or press the Esc (Escape) key. The monitor> prompt is displayed. If needed, enter a question mark (?) to list the available commands.
4. Use the interface command to specify which interface the ping traffic should use. If the PIX 515 has only two interfaces, the monitor command defaults to the inside interface.
5. Use the address command to specify the IP address of the PIX Firewall's interface.
6. Use the server command to specify the IP address of the remote server.
7. Use the file command to specify the filename of the PIX password recovery file. For example, np51.bin.
8. If needed, enter the gateway command to specify the IP address of a router gateway through which the server is accessible.
9. If needed, use the ping command to verify accessibility. If this command fails, fix access to the server before continuing.

Password Recovery Procedure
for the Cisco Secure IDS (formerly NetRanger®) Sensor
Description
This document describes how to recover a password on a Cisco Secure IDS Sensor workstation.
Required Files
The Solaris 2.6 Device Configuration Assistant disk (boot disk).
You can download the files from the Sun support web site.
The Solaris 2.6 for Intel (x86) CD-ROM
Console access to the workstation.
Step-by-Step Procedure
1. Insert the boot disk.
2. Insert the CD in the CD-ROM drive.
3. Turn off the workstation, wait ten seconds, and turn it on.
The system boots from the boot disk, and after some configuration, the initial Configuration Assistant screen is displayed.
4. Press F3 to do a partial scan of the system for boot devices.
When the scan is finished, a list of devices is displayed.
5. Make sure the CD-ROM device appears in the list of devices, and then press F2 to continue.
A screen displays a list of boot devices.
6. Select the CD-ROM drive, and then press the space bar.
You should see an "X" next to the CD-ROM device.
7. Press F2 to continue.
The workstation is now booting from the CD-ROM.
8. On the screen for selecting a type of install, choose Option 2, Jumpstart.
The system continues booting.
9. At the prompt to select a language, choose Option 0 for English.
10. At the next screen for languages, choose Option 0 again for English ANSI.
The system continues to boot and the Solaris Installation screen appears.
11. Press and hold the Control key and type C to stop the installation script and allow you access to the prompt.
12. Type mount -F ufs /dev/dsk/c0t0d0s0 /mnt.

You are now in the shadow file and can remove the password. The entry should be
root:gNyqp8ohdfxPI:10598::::::
where the ":" is a field separator and the encrypted password is the second field.
16. Delete the second field. For example:
root:gNyqp8ohdfxPI:10598::::::
would be changed to
root::10598::::::.
This removes the password for the root user.
17. Type :wq! to write and quit the file.
18. Remove the disk and CD-ROM from the drives.
19. Type init 6 to reboot the system.
20. Type root at the login: prompt and then press Enter.
21. Press Enter at the password prompt.
You are now logged in to the Cisco Secure IDS Sensor.

Command Summary
Creating and Changing Passwords
Catalyst switches support two user modes: user and privileged. The user mode allows the user to enter commands that cannot affect the operational status of the switch. The privileged mode grants the user access to all commands on the switch. Each mode has a separate password. If a user mode password has been set up, the password will be required whenever a user attempts to access the switch via a terminal on the console port or a Telnet connection. If a privileged mode password has been set up, it will be required whenever a user enters the enable command at the user mode command prompt. After the user has successfully entered privileged mode, the command prompt on the switch has "(enable)" added to it.
Generally, passwords should be a mix of uppercase and lowercase letters and at least one number. Eight characters is generally considered sufficient for a secure password. A good example is "BlueSky3". Always consult your corporate security policies before configuring any passwords. Passwords should be changed frequently.
For environments that require a higher level of security, Catalyst switches also support TACACS and Radius authentication. TACACS and Radius support secure password authentication (passwords are not passed in clear text) and logging of commands entered at the command line of the switch. See the Catalyst documentation for more information on configuring these protocols.
Tasks That Will Be Performed
1.
Connect a terminal to the switch.
2.
Enter a user mode password.
3.
Enter a privileged mode password.
4.
Quit the current console session.
5.
Test the new passwords.
Step-by-Step
Step 1. Connect a terminal to the console port of the switch. See Connecting a Terminal to the Catalyst 5000 if you do not know how to do this.
Step 2. Start a user mode console session by pressing the Enter key in your terminal emulation software. You should be prompted for a password. The default user mode password is the Enter key. Press the Enter key when prompted.
Step 3. Go into privileged mode by entering the enable command. The default privileged mode password is the Enter key. Press the Enter key when prompted.
Step 4. Set the user mode password with the setpassword command. (An example password is "BlueSky3".) Press the Enter key when prompted for the old password.
Console> (enable) set password
Enter old password:
Enter new password:
Retype new password:
Password changed.
Console> (enable)
Step 5. Set the privileged mode password with the set enablepass command. (An example password is "RedBird2".) Press the Enter key when prompted for the old password.
Console> (enable) set enablepass
Enter old password:
Enter new password:
Retype new password:
Password changed.
Console> (enable)
Step 6. Terminate your current session by entering the quit command. Then test your new passwords.
Console> (enable) quit
Session Disconnected...

Resetting Lost Passwords
To recover lost passwords, turn the switch off and on again. After the system boots, you will have a 30-second window where the passwords will be returned to the default of the Enter key. You will be able to change the passwords from a management terminal on the console port using the set password and set enablepass commands. When you are prompted to enter the old passwords, press the Enter key, then follow the prompts.
Your original configuration with your new passwords will be in place after you finish this procedure.
Tasks That Will Be Performed
1.
Connect a terminal to the switch.
2.
Power cycle the switch.
3.
Create new (temporary) user and privileged mode passwords.
4.
Create secure passwords.
Note: To ensure that you can change both passwords within 30 seconds, make the new passwords a single character. You can change them to something more secure after the 30-second period is over.
Step-by-Step
Step 1. Connect a terminal to the console port of the switch.
Step 2. Power cycle the switch.
Step 3. After the Running System Diagnostics Message appears, perform the following steps as quickly as possible:
Press the Enter key to start a user mode session.
Press the Enter key when prompted for a user mode password.
Go into privileged mode by entering the {en}able command.
Press the Enter key when prompted for privileged mode a password.
The following output shows this procedure. Keystrokes that are not usually shown are given here for clarity.

20.Cisco路由器口令恢复1020
Password Recovery Procedure
for the Cisco 1020 Router
Description
This document describes how to recover a password on a Cisco 1020 router.
Since the Cisco 1020 router is often not physically secured, to perform a password recovery you must call Cisco Systems or your distribution channel and provide a Cisco 1020 router generated challenge. Using the override program, the support representative can provide a one-time password you can use to enter enable mode.
Notes:
Overrides can be done only from the console.
Press Return at the password prompt if the enable password is not set.
Step-by-Step Procedure
1. From the console, log in to the Cisco 1020 router with username enable and password override.
The 1020 prints a challenge.
2. Provide the support representative with the challenge.
The challenge is used to provide the response.
3. On the 1020 console, log in with username enable and use the response as the password.
You're now in enable mode.
4. Type wr t to see the existing password or type conf t to change the password.
21.Cisco路由器口令恢复600
Cisco 600 Series Password Recovery
The steps below describe how to recover a password on the Cisco 600 series of routers.
Step 1: Enter RMON mode.
To do this, follow the steps below:
1. Connect your PC to the console port of the router.
2. Set your Terminal Access Program (such as HyperTerminal in Windows) to the following settings:
§ Baud rate: 38400 bps recommended (standard 9600 bps possible)
§ Data bits: 8
§ Parity: None
§ Stop bits: 1
§ Flow control: None
3. Power cycle the router (turn the router off, then on using the router's power switch)
4. As soon as you see the Hello! prompt, type Ctrl-C.
5. You are now in RMON mode.
Step 2: If you need to save the configuration file, execute the following command:
db fef80030 100
This command prints the configuration to the screen. The last number indicates the number of bytes to display. Use a value of 100 bytes or more for the number of bytes to display.
Note: You must use the enable password command for the password to display encrypted during password recovery.
Step 3: Look for your encrypted password.
The text of the password will be altered by two letters. For example, using the key a = c, b = d, c = e, and so on, the password "cisco" would be "agqam".
Step 4: (This step is optional.) Erase the current configuration.
An example is shown below:
=>es 6 Erasing sector 00000006...Sector erased =>rb Hello!CBOS v2.0.1.01
Note: This step reboots a Cisco 600 series router with no configuration. You will need to redo the configuration and then use the write command to save the changes to NVRAM.
Step: 5: Reboot the router.
An example is shown below:
rb
22.Cisco路由器口令恢复700
Password Recovery for Cisco 700 Series Routers
This document describes the procedure for performing password recovery on Cisco 750/760 series routers using the NVRAM erase code (750erase.hex or 760erase.hex). Choose the appropriate Terminal Emulation Package (Windows95 and Windows3.1x instruction are included).
1. Power cycle the router. While it is booting up, press the ESC key a couple of times. This will put the unit into a software load mode. The unit will respond with the following prompts:
2. Ready to upload new firmware into flash. Baud (1=19.2K, 2=2400, 3=38.4K, 9=9600)?
3. Select the baud rate for the transfer (in this example 9600 is chosen). The unit will respond with the following prompt.
4. Begin ascii upload at 8n1/9600 baud.
5. Start the ascii file transfer of the image, 750erase.hex for the 750 series or 760erase.hex for the 760 series. These files are not interchangeable. This file must be treated as a text file for loading into the unit via the console port. At 9600, the transfer takes approximately 12 minutes. While the transfer is occuring, the LINE LED will be flashing rapidly. When the transfer is complete the unit will respond with the following prompts and then reboot itself:
6. Firmware transfer successful.7. Now writing firmware into FLASH, standby ...8. Firmware upload complete.9. Erase Version of 750/760 firmware This will erase all configured parameters10. ERASING NVRAM...11. (reboots itself)12. Ready to upload new firmware into flash.13. Baud (1=19.2K, 2=2400, 3=38.4K, 9=9600)?14. At this point, reload the original software repeating step 2.
Procedure for performing a text/ascii transfer using Windows95 Hyperterminal
1. Choose Properties from the File Menu
2. Choose Settings Tab
3. Choose ASCII Setup Button
4. Make sure that both "Line Delay" and "Character Delay" are set to zero.
5. Make sure that "Send line ends with line feeds is check marked".
6. Click the OK Button on both screens.
7. Close Hyperterminal and then restart it.
8. Choose Send Text File... from the Transfer menu.
9. Locate file (may have to change Files of Type to All Files) and highlight it.
10. Click the OK Button.
The file is now being transferred to the unit...there may not be any indication that the file is transferring except for the LINE LED on the front of the unit. While the transfer is occuring, the LINE LED will be flashing rapidly on the front of the unit.
Procedure for performing a text/ascii transfer using Windows Terminal
1. Choose Text Transfers... from the Settings Menu.
2. Make sure that "Standard Flow Control" is chosen.
3. Click the OK Button.
4. Choose Send Text File... from the Transfer Menu.
5. Locate file (may have to change List Files of Type to All Files) and highlight it.
6. Make sure that neither Append LF nor Strip LF are check marked.
7. Click the OK Button.
The file is now being transferred to the unit...there may not be any indication that the file is transferring except for the LINE LED on the front of the unit. While the transfer is occuring, the LINE LED will be flashing rapidly on the front of the unit.

24.Cisco路由器口令恢复800
Password Recovery Procedure
for the Cisco 800
Description
This document describes the password recovery procedure for the Cisco 800.
Step-by-Step Procedure
1. 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
The required console cable specifications are described in Cabling Guide for RJ-45 Console and AUX Ports (Cisco's 1000 series, 2500 series, and AS5100).
2. Type show version and record the setting of the configuration register. Click
here
to see output of a show version command.
The configuration register setting is usually 0x2102 or 0x102.
3. Using the switch, turn off the router and then turn it on.
4. Press Break on the terminal keyboard within 60 seconds of the powerup to put the router into ROMMON.
If the break sequence doesn't work, see Possible Key Combinations for Break Sequence During Password Recovery for other key combinations.
5. Type set ios-conf = 142 at the boot# prompt.
If Flash is intact, the best setting is 0x42.
If the Flash is not installed or is erased, use the 0x41 setting. Note that with this setting you can view or erase the configuration but cannot change the password.
6. Type boot at the boot#> prompt to initialize the router.
The router reboots but ignores its saved configuration.
7. Type no after each setup question or press Ctrl-C to skip the initial setup procedure.
8. Type enable at the Router> prompt.
You'll be in enable mode and see the Router# prompt.
9. Important Type config mem or copy start running to copy the nonvolatile RAM (NVRAM) into memory. Do not type config term.
10. Type wr term or show running.
The show running and wr term 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.
11. Type config term and make the changes.
The prompt is now hostname(config)#.
12. Type enable secret .
13. Issue the no shutdown command on every interface that is used. If you issue a show ip interface brief command, every interface that you want to use should be "up up".
14. Type config-register 0x2102, or the value you recorded in step 2.
15. Press Ctrl-z to leave the configuration mode.
The prompt is now hostname#.
16. Type write mem or copy running startup to commit the changes.

25.Cisco路由器口令恢复cs500
Password Recovery Procedure
for the Cisco cs500 Communication Server
Description
This document describes how to recover a password on a Cisco cs500 communication server.
The Cisco cs500 does not have a console port so to recover a password you must erase the configuration then configure the server again.
Step-by-Step Procedure
1. Unplug the Cisco cs500 server.
2. Press and hold the DEFAULT button on the front of the chassis.
3. Turn on the server.
The OK and LAN LEDs blink on and off.
4. When the OK and LAN LEDs blink off (after about 15 seconds), release the DEFAULT button.
The 500-CS enters setup mode in about two to ten minutes.
5. Configure the server.
