Hierarchy Level


Set the boot-loader password for accessing the U-Boot CLI during the boot process. The password can be entered either as a plain-text password or as an encrypted password.

Encrypted passwords must be entered in Message Digest 5 (MD5) format. Plain-text passwords are encrypted by using MD5 by default. The encryption format for plain-text passwords can be changed by using the set system login password format command.

Encrypted passwords must be between 1 and 128 characters long. The password must be enclosed in quotation marks and cannot be blank within the quotation marks (“ “).

The default requirements for plain-text passwords are as follows:

  • The password must be between 6 and 128 characters long

  • You can include most character classes in a password (uppercase letters, lowercase letters, numbers, punctuation marks, and other special characters). Control characters are not recommended.

  • The password must contain at least one change of case or character class.


encrypted-password password— Enter a password that has already been encrypted. You can specify only one encrypted password.

plain-text-password—Enter a plain-text password. The CLI prompts you for the password and then encrypts it. The CLI displays the encrypted version, and the software places the encrypted version in its user database. You can specify only one plain-text password.
