A user account specifies a user's level of access to the device CLI.
EFA uses role-based access control (RBAC) as the authorization mechanism. A role is a container for rules that specify which commands can be run and with which permissions. When you create a user account, you specify a role for that account. In general, user (as opposed to user-level) refers to any account to which an admin or user role can be assigned.
