802.1x and MAC Address Mixed Authentication mode: 802.1x is first

Latest reply: Dec 21, 2018 09:27:19 1262 6 10 0

In NAC network deployment, 802.1x authentication and MAC address authentication can be deployed on interfaces of access users to flexibly adapt to various authentication requirements. In this manner, users can access the network in any authentication mode.


After multiple authentication modes are deployed, the device allows users to access the network in different modes by default to grant different network rights to users.


In this example, MAC address authentication is performed. If the authentication fails, 802.1X authentication is performed.

The unified mode is used.

so when configured with 802.1x and mac address authentication, you said the device will check the 802.1x first, if I passed the 802.1x checking, does it mean that I can get through the device without the mac address checking ?
