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
815H

In non-FIPS mode, all the combination levels are available for a password. In FIPS mode, only the level
4 combination is available for a password.
When a user sets or changes a password, the system checks if the password meets the combination
requirement. If not, the operation fails.
