MAC Address Authentication By RADIUS Lookup

Authenticate clients by using a RADIUS server to look up their MAC address and allow connections only from listed devices.

When configuring a WLAN, you can enable MAC Authentication with any security type except WPA3/WPA2 Enterprise.

MAC Authentication in the Edit WLAN Window

Keep these points in mind:

  • RADIUS Server—A RADIUS Server is used to authenticate using MAC address as username and password.
  • Change of Authorization(COA)—An external server can instruct the reauthentication of a client.
  • The VLAN can be untagged, tagged, or dynamic.
  • Guest Access with MAC Authentication Bypass can be enabled to leverage RADIUS-based guest portals.
Note:

You also can configure Guest Access with MAC Authentication Bypass. For help, see Guest Access Using RADIUS Server with MAC Authentication Bypass.
