Configuring User Privilege Levels and Command
Levels
Introduction
To restrict different users’ access to the device, the system manages the users by their privilege levels. User
privilege levels correspond to command levels. After users at different privilege levels log in, they can
only use commands at their own, or lower, levels. All the commands are categorized into four levels,
which are visit, monitor, system, and manage from low to high, and identified respectively by 0 through
3. Table 3 describes the levels of the commands.
