Configuring user privilege and command levels
To avoid unauthorized access, the device defines the user privilege levels and command levels in Table
24. User privilege levels correspond to command levels. A user who has been logged in with a specific
privilege level can use only the commands at that level or lower levels.
All commands are categorized into four levels: visit, monitor, system, and manage, and are identified
from low to high, respectively by 0 through 3.
