14 Configuring 802.1X Port Authentication

The operation of dot1x on the switch requires the following:

The switch must have an IP address assigned.

The IP address of the RADIUS server must be specified.

802.1X must be enabled globally for the switch.

Each switch port that will be used must be set to dot1x “Auto” mode.

Each client that needs to be authenticated must have dot1x client software installed and properly configured.

The RADIUS server and 802.1X client support EAP. (The switch only supports EAPOL in order to pass the EAP packets from the server to the client.)

The RADIUS server and client also have to support the same EAP authentication type – MD5. (Some clients have native support in Windows, otherwise the dot1x client must support it.)
