How to configure a user level on an AR router
Methods of configuring user levels vary with specific scenarios (command lines):
- Configure a user level for a user.
[Huawei] aaa
[Huawei-aaa] local-user user1 privilege level 15  //Set the user level of user 1 to 15.  
-  Configure a user level for all users under a domain.
[Huawei] aaa
[Huawei-aaa] service-scheme sch1
[Huawei-aaa-service-sch1] admin-user privilege level 15  //Set the user level of all users under a domain to 15.  
-  Configure a user level for all users who log in through a page (take the VTY view as an example).
[Huawei] user-interface maximum-vty 15
[Huawei] user-interface vty 0 14
[Huawei-ui-vty0-14] user privilege level 15  //Set the user level in the VTY 0 to VTY 14 views to 15.
The preceding command is used to modify a user level as well. This command overwrites preceding operation results. Therefore, if this command is run multiple times, the last-time operation prevails.
If the user level configured on a page conflicts with the corresponding operation permission of a user, the operation permission prevails.

Description of user levels on AR routers
User levels on AR routers are as follows: You can configure different user levels to control access rights of different users and improve device security. There are 16 user levels numbered from 0 to 15, in ascending order of priority. Visit level-0: It is used for network diagnosis, access to the external device, such as ping, tracert, and Telnet. Monitoring level-1: It is used for system maintenance, including display commands and other commands. Some display commands are unavailable at this level. For example, the display current-configuration and display saved-configuration commands are level-3 management commands. Configuration level-2: Service configuration commands. Management level-3 to 15: They are used to control basic system operations, including system file, FTP/TFTP download, user management, command level setting, and debugging commands. User levels correspond to the command levels. Users can use only the commands at the same or lower level than their own levels. By default, users logging in from the console port can run level 15 commands. By default, the user level of other login modes is 0 (visit level), that is, after the user logs in to a device, the user can only run the commands at level 0, including ping, tracert, and other commands for network diagnosis.

Does the router support user level settings using RADIUS
