What to do if a WLAN device user has insufficient permissions to configure the device

Hierarchical management of users and commands is implemented to restrict users' permissions to access a WLAN device and their operations on this device. User levels correspond to command levels. After logging to a WLAN device, users of each level can use only the commands whose levels are equal to or lower than the corresponding user level.
If a Telnet user or console user (assuming that the account of a low user level is client) cannot perform some configurations due to its low level, change the user level based on the following conditions:
1. If the user authentication mode is AAA and the device has other high-level users, the user level is determined by the local-user user-name privilege level level command in the AAA view. Log in to the device as a high-level user, and then change the level of client in the AAA view. The configurations are as follows:
[HUAWEI] aaa
[HUAWEI-aaa] local-user client privilege level 3
[HUAWEI-aaa] return
2. Specifically, if the user authentication mode is password and the login mode is Telnet, the user level is determined by the user privilege level level command of the VTY interface. If the low-level client has been configured only for partial VTY channels, log in to the device through a high-level VTY channel, and then change the user level of low-level VTY channels. The following is an example of changing the user level of VTY 0-4:
[HUAWEI] user-interface vty 0 4
[HUAWEI-ui-vty0-4] user privilege level 3
[HUAWEI-ui-vty0-4] return
