In cases where the 7210 SAS platform is not installed in a physically secure location, the user can encrypt the BOF and the configuration file to halt or hinder interpretation of the contents of the file.
By default, the BOF and configuration file are not encrypted. When encryption is enabled for either file and a change is saved (using the admin save command), the original file is moved to filename.1 and the encrypted file becomes the new filename.cfg.
When the original file is moved to filename.1, this file is unencrypted. To maintain node security, delete the unencrypted filename.1 file.
When the BOF is encrypted on the compact flash, the BOF parameters can be modified using the BOF interactive menu during node startup, and fields can be modified using this menu.
See Configuring BOF encryption for information about configuring BOF encryption. See Configuring the BOF interactive menu password for information about configuring the BOF interactive menu password. See Configuring the configuration file encryption for information about configuring configuration file encryption.
