Recovering a Lost Password

Troubleshooting Cisco 3800 Series Routers

OL-5972-01

Note The jumpers are not needed to troubleshoot Cisco IOS problems. If the Cisco IOS software becomes

corrupted, remove the CompactFlash memory card to force the router to boot in ROM monitor mode.

Change these settings only after consulting with your service representative or Cisco technical support.

Recovering a Lost Password

You can recover a lost enable password, but an enable secret password is encrypted and is not

recoverable. If you lose an enable secret password configured on your router, you can replace it with a

new enable secret password.

For password recovery and replacement procedures, see
