Step-by-Step Procedure
1. Attach a terminal or PC with terminal emulation to the console port of the router. Use these terminal settings:
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
2. Powered off and power on switch. Press Break on the terminal keyboard right after the SUP2T/6807-XL switch boots up. If you don't have the break key on the laptop use "break" sequence on PUTTY. From this point on, the password recovery procedure is the same as for any other router.
Recommendation. Always use "Windows laptop" with Putty. MACBOOK does not work for password recovery as it does not send the break sequence and waste lots of time.
Note: If you have dual supervisor , remove one supervisor before power off/on switch otherwise when you will change the config-register value and reset, switch will boot up with other superviosr where you did not change config-register vlaue.
3.Type confreg 0x2142 at the rommon 1> prompt to boot from Flash without loading the configuration.
4. Type reset at the rommon 2> prompt.
5. The switch reboots. However, it ignores the saved configuration.
6. Type no after each setup question or press Ctrl-C to skip the initial setup procedure.
7. Type enable at the Switch> prompt.
8. Issue the configure memory or copy start running commands to copy the Nonvolatile RAM (NVRAM) into memory. Do not issue the configure terminal command.
9. The prompt is now switch(config)#. Issue the enable secret < password > command in global configuration mode to change the enable password.
10. Issue the config-register 0x2102 command, or the value you recorded in Step 2 in global configuration mode (Switch(config)#) to set the configuration value back to its original value.
