(Optional) Configuring the 802.1x Authentication Method

(Optional) Configuring the 802.1x Authentication Method

Context

This command can be configured in the system view or interface view. The configuration in the system view takes effect on all interfaces, and that in the interface view takes effect only on a specified interface. If the command is configured both in the system view and interface view, the configuration in the interface view takes precedence.

Procedure

  • In the system view,

    1. Run system-view

      The system view is displayed.

    2. Run dot1x authentication-method { chap | pap | eap }

      The 802.1x authentication method is configured.

      By default, the 802.1x authentication method is CHAP.

      • Password Authentication Protocol (PAP) is a two-way handshake authentication protocol. It transmits passwords in plain text format in RADIUS packets. It is not recommended because of the low security.
      • Challenge Handshake Authentication Protocol (CHAP) is a three-way handshake authentication protocol. It transmits only user names but not passwords in RADIUS packets. CHAP is more secure and reliable than PAP. If higher security is required, CHAP is recommended.
      • Extensible Authentication Protocol (EAP) authentication: The device directly encapsulates the received EAP packets containing user authentication information into RADIUS packets and sends the RADIUS packets to the RADIUS server. This mechanism is also called EAP over RADIUS (EAPoR). To use the EAP-MD5 authentication, you only need to enable EAP authentication.

      PAP authentication and CHAP authentication are termination authentication methods and EAP authentication is a kind of relay authentication method.

    3. Run commit

      The configuration is committed.

  • In the interface view,

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run dot1x authentication-method { chap | pap | eap }

      The 802.1x authentication method is configured.

      By default, the 802.1x authentication method is CHAP.

    4. Run commit

      The configuration is committed.
