The password recovery feature is enabled by default and provides a method for regaining management access to the switch (without resetting the switch to its factory default configuration) in the event that the system administrator loses the local manager username (if configured) or password. Using password recovery requires:
Disabling the password recovery process means that the only method for recovering from a lost manager username (if configured) and password is to reset the switch to its factory-default configuration, removing any non-default configuration settings.

Syntax:
Enables or disables the ability to recover a lost password.
When enabled, the switch allows management access through the password recovery process described below. This provides a method for recovering from lost manager usernames and passwords.
When disabled, the password recovery process is disabled and the only way to regain management access to the switch is to use the Reset+Clear button combination. See Restoring the factory default configuration to restore the switch to its factory default configuration.

Steps for disabling password-recovery
:
-
Use
show front-panel-security
to determine whether the factory-reset parameter is enabled. If it is disabled, use thefront-panel-security factory-reset
command to enable it. -
Press and release the Clear button on the front panel of the switch.
-
Within 60-seconds of pressing the Clear button, enter the following command:
[no] front-panel-security password-recovery
Steps for disabling password-recovery
Switch(config)# no front—panel—security password—recovery **** CAUTION **** Disabling the clear button without password recovery prevents switch passwords from being reset. If the switch password is lost, restoring the default factory configuration will be required to regain access! Continue with disabling password recovery [y/n]?
If you lose the manager username/password, but password-recovery
is enabled, then you can use the password recovery process to gain management access to the switch with an alternate password supplied by HP Networking Support.

-
Note the switch base MAC address. It is shown on the label located on the upper right front corner of the switch.
-
Contact HP Networking Support for further assistance. Using the switch MAC address, HP Networking Support will generate and provide a "one-time use" alternate password to gain management access to the switch. Once you gain access, configure a new, known password.
|
|
NOTE: The alternate password provided by HP Networking Support is valid only for a single login attempt. You cannot use the same "one-time-use" password if you lose the password a second time. Because the password algorithm is randomized based upon your switch MAC address, the password will change as soon as you use the "one-time-use" password provided by HP Networking Support. |
