M4300 Series and M4300-96X Fully Managed Switches The CLI command to enable authentication is as follows. (Netgear Switch)#configure (Netgear Switch)(Config)#authentication enable Configure a Dot1x-MAB Authentication Method List with MAB-Dot1x Priority Note: This section describes how to configure the authentication order and priority. For information about configuring the MAB authentication method, see Configure MAC Authentication Bypass on a Switch on page 393. If the switch authenticated a client by using MAB but the client is enabled for dot1x after it is authenticated, the EAPOL start frames that the client sends to the authentication manager causes the port to be placed in the unauthorized state and the switch then attempts to authenticate the client by using dot1x. This situation occurs because the default priority for dot1x authentication is higher than the default priority for MAB authentication. To prevent the port from being placed in the unauthorized state, assign MAB authentication a higher priority than dot1x authentication. In that situation, if the client sends EAPOL start frames to the authentication manager, the authentication manager selects the first configured authentication method in the list, that is, dot1x, and compares the priority of the current authenticated method (that is, MAB) with the newly selected method (that is, dot1x). Because the priority for MAB authentication is higher than the priority for dot1x authentication, the authentication manager does not start dot1x authentication. The CLI command to enable authentication is as follows. (Netgear Switch)#configure (Netgear Switch)(Config)#authentication enable Configure a Dot1x, MAB, and Captive Portal Authentication Method List with Default Priority Note: This section describes how to configure the authentication order and priority. For information about configuring the captive portal authentication method, see Chapter 36, Captive Portals. Security Management 382 Software Administration Manual
