Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Password strength

By default, the password you configure with the username password role and enable password priv-lvl commands must be at least nine alphanumeric characters. To increase password strength, you can create stronger password rules using the password-attributes command. These password rules apply to the user name and privilege-level password configuration.

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, from 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, from 0 to 31; default 0.
    • lower number — Minimum number of lowercase characters required, from 0 to 31; default 0.
    • numeric number — Minimum number of numeric characters required, from 0 to 31; default 0.
    • special-char number — Minimum number of special characters required, from 0 to 31; default 0.

To turn off the strong password check enabled with the password-attributes command, use the service simple-password command. No password rules, except for the minimum 9-character requirement, are applied to the user name and privilege-level passwords. To revert to the configured password-attributes settings, use the no service simple-password command.
