Troubleshooting Password Recovery
To troubleshoot password recovery, pay attention to the following:
•
You cannot determine whether password recovery has been disabled in the sensor configuration
from the ROMMON prompt, GRUB menu, switch CLI, or router CLI. If password recovery is
attempted, it always appears to succeed. If it has been disabled, the password is not reset to cisco.
The only option is to reimage the sensor.

The only option is to reimage the sensor.
•
You can disable password recovery in the host configuration. For the platforms that use external
mechanisms, such as the AIM IPS and NME IPS bootloader, ROMMON, and the maintenance
partition for the IDSM2, although you can run commands to clear the password, if password
recovery is disabled in the IPS, the IPS detects that password recovery is not allowed and rejects the
external request.
