Password strength

By default, the password you configure with the username password command must be at least nine alphanumeric characters.

To increase password strength, you can create password rules using the password-attributes command. When you enter the command, at least one parameter is required. When you enter the character-restriction parameter, at least one option is required.

  • Create rules for stronger passwords in CONFIGURATION mode.
    password-attributes {[min-length 
                                        number] [character-restriction {[upper 
                                        number] 
                                        [lower 
                                        number][numeric 
                                        number] [special-char 
                                        number]}}
                                     
    • min-length number — Enter the minimum number of required alphanumeric characters (6 to 32; default 9).
    • character-restriction — Enter a requirement for the alphanumeric characters in a password:
      • upper number — Minimum number of uppercase characters required (0 to 31; default 0).
      • lower number — Minimum number of lowercase characters required (0 to 31; default 0).
      • numeric number — Minimum number of numeric characters required (0 to 31; default 0).
      • special-char number — Minimum number of special characters required (0 to 31; default 0).
