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.

  CAUTION: Although empty passwords are supported, it is recommended that you use strong passwords for all production switches.
  NOTE: Only an administrator can change the password of a user assigned to the operators role.
