Use this command to instruct the system to verify new passwords against a list of all previously used passwords, once an account successfully changes a password.
The limit is the number of previous passwords that the system checks against in the record to verify the new password.
If this parameter is configured, the system returns an error message if a user attempts to change the password to one that is saved by the system (up to the configured limit) for that account; this applies to both user and administrative accounts. This also applies to a configured password on the default admin account on the switch.
The limit of previous passwords that the system checks for previous use is configurable from 1 to 10. Using the none option disables previous password tracking and returns the system to the default state of no record of previous passwords.
The following command instructs the system to verify that the new password has not been used as a password in the previous 5 passwords for the account engineering:
configure account engineering password-policy history 5
