I have a cisco 1601 router. I'm trying to reset the password over the console port, but I'm having some trouble, I've never done this before. I'm trying to follow the directions in a pdf I found, but the router is saying the config-register command doesn't exist.
Easton>confreg 0x142
Translating "confreg"
% Unknown command or computer name, or unable to find computer address

Hi,
1) - Before reloading, note the value of the configuration register from "show version" command, generally 0x2102
Router#sh ver
...
Configuration register is 0x2102
2) - reload the router:
Router#reload
if havenot the access to the router (lost password) make a cool boot
3) - Type the break sequence during bootup to enter the ROM monitor mode (ROMMON):
"ALT-B" or "ALT-C"
4) - Use "confreg" command to change the value of the configuration command to make the router ignore the startup configuration in the next bootup:
Rommon1>confreg 0x2142
5) - reboot by typing:
i
6) - Break the setup system config dialog or type "n" to not erase the NVRAM Backup config file
7) - restore your startup config and change the password
8) - Now you can restore the config registry value from 0x2142 to 0x2102:
Router(config)#config-register 0x2102
!!!!NOTE that with a physical access to the device you can do everything you want, so first and before anything make sure that your devices are physically secured!!!!
I hope this will help you!
