Cisco Password Recovery (most routers).


The following procedure is pretty standard and works on most Cisco devices.

 

  • Connect to the device via it's console port setting your terminal emulator to 9600/8/N/1 and power cycle it.
  • As soon as it starts to POST, send it a BREAK signal (depends on your terminal emulator) to drop it into ROMMON.
  • At the prompt, type confreg 0x2142
  • Then type reset and let the device reboot completely (do not use ctrl-c to skip config dialog).
  • After the device comes up, go into enable mode
  • copy startup-config running-config
  • show run to make sure it looks good.
  • Go into config mode (config t)
  • Enter the new secret password (enable secret)
  • Make sure to do a no shut on all the interfaces that should be up.
  • Type config-register 0x2102.
  • Type end to exit config mode.
  • Save the config using write mem.
