Role assignment is as follows:
l If both machine and user authentication succeed, the role is dot1x_user. If there is a server-derived role, the
server-derived role takes precedence.
l If only machine authentication succeeds, the role is dot1x_mc.
l If only user authentication succeeds, the role is guest.
l On failure of both machine and user authentication, the user does not have access to the network.
With machine authentication enabled, the VLAN to which a client is assigned (and from which the client obtains
its IP address) depends upon the success or failure of the machine and user authentications. The VLAN that is
ultimately assigned to a client can also depend upon attributes returned by the authentication server or server
derivation rules configured on the controller (see Understanding VLAN Assignments on page 171). If machine
authentication is successful, the client is assigned the VLAN configured in the virtual AP profile. However, the
client can be assigned a derived VLAN upon successful user authentication.
You can optionally assign a VLAN as part of a user role configuration. Do not use VLAN derivation if you
configure user roles with VLAN assignments.
Table 70 describes VLAN assignment based on the results of the machine and user authentications when VLAN
derivation is used.

The administrator can now associate a VLAN ID to a client data based on the authentication credentials in a bridge
mode.
Enabling 802.1x Supplicant Support on an AP
ArubaOS provides 802.1X supplicant support on the Access Point (AP). The AP can be used as a 802.1x
supplicant where access to the wired Ethernet network is restricted to those devices that can authenticate
