Password requirements

Passwords must:

  • Contain only ASCII characters from hexadecimal 21 to hexadecimal 7E [\x21-\x7E] (decimal 33 to 126). Spaces are not allowed. When the password is entered directly without prompting, the "?" symbol (hexadecimal 3F [\x3F] (decimal 63)) is not permitted.

  • Contain at most 32 characters.

  • Contain at least the number of characters configured (optionally) for minimum-password-length.

  • Not be blank. On a factory-default switch, the admin user has a blank password. If the admin user password is changed, it can only be reset to blank by reverting the switch to factory defaults.


    Only an administrator can change the password of a user assigned to the operators role.
