Overview of User Management
User management allows you to manage users, user levels, user permissions, and other user-related tasks. There are three user levels:
-
Normal user: Normal users have the lowest privilege level. They can only enter execution configuration mode and view system configuration information. However, normal users cannot make any configuration changes, including modifying their own password.
-
Administrator: Administrators have all the rights of normal users, including configuring a device and modifying their own password. However, administrators cannot add new users or modifying the passwords of other users.
Note
Unless otherwise specified, all the configuration logging in references indicate an admin logging in.
-
Super user: A super user is the default user created in a device. A device can have only one super user who cannot be deleted. A super user has all the permissions, including performing all switch configurations, adding new users, modifying users' passwords as well as their own, and deleting users. The default login password for a super user is 123456.

About Silence Mechanism
The Silence Mechanism feature allows you to configure the consecutive login failure limit for each user. If the number of consecutive login failures exceed the limit, the corresponding user will be locked out and not allowed to log in for a certain period, which is known as silent time. This feature is disabled by default.
