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 specific privilege level logs in, the user can only
use commands at that level, or lower levels.
All the commands are categorized into four levels: visit, monitor, system, and manage, and are identified
from low to high, respectively by 0 through 3.
