Configuring password control
Overview
Password control refers to a set of functions provided by the device to manage login and super password
setup, expirations, and updates for device management users, and to control user login status based on
predefined policies.
Local users are divided into two types: device management users and network access users. This feature
applies only to device management users. For more information about local users, see "Configuring
AAA."
Password setting
Minimum password length
You can define the minimum length of user passwords. If a user enters a password that is shorter than the
minimum length, the system rejects the password.
Password composition policy
A password can be a combination of characters from the following types:
• Uppercase letters A to Z.
• Lowercase letters a to z.
• Digits 0 to 9.
• Special characters. For information about special characters, see the password-control composition
command in Security Command Reference.
Depending on the system's security requirements, you can set the minimum number of character types a
password must contain and the minimum number of characters for each type, as shown in Table 5.

When a user sets or changes a password, the system checks if the password meets the combination
requirement. If not, the operation will fail.
Password complexity checking policy
A less complicated password such as a password containing the username or repeated characters is
more likely to be cracked. For higher security, you can configure a password complexity checking policy
to make sure all user passwords are relatively complicated. With such a policy configured, when a user
