Configuring User Privilege and Command Levels
Introduction
To avoid unauthorized access, the switch defines user privilege levels and command levels. User
privilege levels correspond to command levels. When a user at a privilege level logs in, the user can
only use commands at that level, and 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 1-5 describes the levels of the commands.
