You are required to enter the name of the value to be added as well as its value. Values can only be added to attributes that are of integer type. Deleting Attribute Value Values that have been added to a vendor-specific attribute can be deleted using the Delete Value button. Attribute values with a lock symbol ( ) next to their name are standard RADIUS dictionary entries and cannot be deleted. EAP and 802.1X Authentication and Certificate Management The Extensible Authentication Protocol (EAP) supports multiple types of authentication methods, including digital certificates, smart cards, and passwords. This authentication protocol is the basis for the IEEE 802.1X standard, which provides port-based network access control for both wired and wireless networks. ClearPass Guest supports EAP and 802.1X authentication. This authentication method requires EAP messages to be encapsulated inside RADIUS packets. The RADIUS server must also be configured with the appropriate settings for the EAP types that will be used. To view or modify a RADIUS server's EAP configuration, go to RADIUS > Authentication, then either click EAP & 802.1X in the left navigation, or click the Extensible Authentication Protocol command. The Extensible Authentication Protocol page opens, and includes command links for EAP configuration and certificate management for the RADIUS server. 146 | RADIUS Services ClearPass Guest 3.9 | Deployment Guide
