Recovering the Password
Verifying the State of Password Recovery
Use the show settings | include password command to verify whether password recovery is enabled.
To verify whether password recovery is enabled, follow these steps:
Step 1
Log in to the CLI.
Step 2
Enter service host submode.
sensor# configure terminal
sensor (config)# service host
sensor (config-hos)#
Step 3
Verify the state of password recovery by using the include keyword to show settings in a filtered output.
sensor(config-hos)# show settings | include password
password-recovery: allowed <defaulted>
sensor(config-hos)#
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.

•
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 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.
