Encryption module changes
VOSS 4.2 release includes the encryption modules in the image file. Therefore, the commands
load-encryption-module and software add-modules have been removed. The commands
are no longer required for the current release to load the encryption modules. However, if you
downgrade the switch from the VOSS 4.2 version, you continue to require these commands. For
more information, see the procedure for downgrading the software in Release Notes for VSP
Operating System Software, NN47227-401.
Enhanced secure mode
VOSS 4.2 release adds support for the new boot config flags enhancedsecure-mode
command. If you enable enhanced secure mode, the system can provide role-based access levels,
strong password requirements, and strong rules on password length, password complexity,
password change intervals, password reuse, and password maximum age use.
