aging: Enables the password expiration feature.
composition: Enables the password composition restriction feature.
history: Enables the password history feature.
length: Enables the minimum password length restriction feature.
Usage guidelines
For a specific password control feature to take effect, make sure the global password control and the
specific password control feature are both enabled. For example, if the global password control and
the minimum length restriction feature are not enabled, the password-control length command
does not take effect.
The system stops recording history passwords after you execute the undo password-control
history enable command, but it does not delete the prior records.
If the global password control feature is enabled but the minimum password length restriction feature
is disabled, the following rules apply:
•
In non-FIPS mode, a password must contain a minimum of 4 characters and a minimum of 4
characters must be different.
•
In FIPS mode, a password must contain a minimum of 15 characters and a minimum of 4
characters must be different.
