Cisco Cisco IPS 4255 Sensor

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)#

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 the 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.

To check the state of password recovery, use the show settings | include password command. 

When performing password recovery on the IDSM2, you see the following message: 

Upgrading 

will wipe out the contents on the storage media

. You can ignore this message. Only the 

password is reset when you use the specified password recovery image.

This section describes the Bug Toolkit, lists the resolved caveats, and contains the following topics:

For the most complete and up-to-date list of caveats, use the Bug Toolkit to refer to the caveat release 
note. You can use the Bug Toolkit to search for known bugs based on software version, feature set, and 
keywords. The resulting matrix shows when each bug was integrated, or fixed if applicable. It also lets 
you save the results of a search in Bug Groups, and also create persistent Alert Agents that can feed those 
groups with new defect alerts.
