Switching User Level
Overview
Users can switch their user privilege level temporarily without logging out and disconnecting the current
connection; after the switch, users can continue to configure the device without the need of relogin and
reauthentication, but the commands that they can execute have changed.
For example, if the current user privilege level is 3, the user can configure system parameters; after
switching the user privilege level to 0, the user can only execute some simple commands, like ping and
tracert, and only a few display commands.
The switching of user privilege level is temporary, and effective for the current login; after the user relogs
in, the user privilege restores to the original level.
To avoid misoperations, the administrators are recommended to log in to the device by using a lower
privilege level and view device operating parameters, and when they have to maintain the device, they
can switch to a higher level temporarily; when the administrators need to leave for a while or ask
someone else to manage the device temporarily, they can switch to a lower privilege level before they
leave to restrict the operation by others.
The high-to-low user level switching is unlimited. However, the low-to-high user level switching requires
the corresponding authentication. Generally, two authentication modes are available: the super
password authentication mode and HWTACACS authentication mode.

Specifying the authentication mode for user level switching
The low-to-high user level switching requires the corresponding authentication. The super password
authentication mode and HWTACACS authentication mode are available at the same time to provide
authentication redundancy.
The configuration of authentication mode for user level switching is performed by Level-3 users
(administrators).
Follow these steps to specify the authentication mode for user level switching:
