If no access restriction other than 802.1X is configured on the port, then a client device will have full access on the configured VLAN. When preauthentication open access is enabled, initial traffic on the port is restricted only by whatever other access restriction, independent of 802.1X, is configured on the port. For example, if open authentication is enabled with single-host mode, then the port will allow only one MAC address.

Open authentication is enabled by entering theĪuthentication open command after host mode configuration, and acts as an extension to the configured host mode. For information about configuring IEEE 802.1X host modes, see the “Configuring the Host Mode” section of the “Configuring IEEE 802.1X Port-Based Authentication” chapter. IEEE 802.1X Open Authentication and Host ModesĪny of the four host modes (single-host mode, multiple-host mode, multi-domain authentication mode, and multiauthentication mode) may be configured to allow a device to gain network access before authentication.

The Network Edge Access Topology (NEAT) feature is not supported Should use static default ACLs to restrict Layer 3 traffic. Restrictions for IEEE 802.1Xĭoes not support standard ACLs on the switch port.Īuthentication open interface configuration command, any new MAC addressĭetected on the port will be allowed unrestricted Layer 2 access to the networkĮven before any authentication has succeeded. For more information, see theĬonfiguration Guide for CISCO Secure ACS. The switch must have a RADIUS configuration and be connected to the Cisco secure access control server (ACS). For more information, see the documentation for your Cisco platform and theĬisco IOS Security Configuration Guide: Securing User Services.

You should understand the concepts of the RADIUS protocol and have an understanding of how to create and apply access control lists (ACLs). The web authentication method is not supported on Cisco integrated services routers (ISRs) or Integrated Services Routers Generation 2 (ISR G2s) in Cisco IOS Release 15.2(2)T. If the authentication order includes web authentication, configure a fallback profile that enables web authentication on the switch and the interface. If the authentication order includes the 802.1X port authentication method, you must enable IEEE 802.1X authentication on the switch.

If appropriate, you must enable ACL download. The switch must be connected to a Cisco secure Access Control System (ACS) and RADIUS authentication, authorization, and accounting (AAA) must be configured for Web authentication. For more information, see theĬonfiguring IEEE 802.1X Port-Based Authentication module. You should understand the concepts of port-based network access control and have an understanding of how to configure port-based network access control on your Cisco platform.

Open authentication is useful in an applications such as the Preboot Execution Environment (PXE), where a device must access the network to download a bootable image containing an authentication client. IEEE 802.1X Open Authentication allows a host to have network access without having to go through IEEE 802.1X authentication.
