Not all Cisco ISR routers support all the components listed. High-speed WAN interface cards (HWICs) without ACL support: The following cards or modules support switch ports:Įnhanced High-speed WAN interface cards (EHWICs) with ACL support: The following Cisco ISR-G2 routers are supported: Optimal performance is obtained with a connection that has a maximum of eight hosts per port.

The IEEE 802.1X Port-Based Authentication feature is available only on Cisco 89x and 88x series integrated switching routers (ISRs) that support switch ports. The port must be successfully authenticated. See the IEEE 802.1X Authenticator feature module for information. A method list describes the sequence and authentication method to be queried to authenticate a user. The authentication method list must be enabled and specified. Http:// and set the SupplicantMode registry to 3 and the AuthMode registry to 1.Īuthentication, authorization, and accounting (AAA) must be configured on the port for all network-related service requests. See the Microsoft Knowledge Base article at the location If you do not configure the IEEE 802.1X supplicant, an EAP-logoff message is not sent to the switch and the accompanying accounting Stop message is not sent to the authentication server. You must configure the IEEE 802.1X supplicant to send an EAP-logoff (Stop) message to the switch when the user logs off.

You should understand the concepts of the RADIUS protocol and have an understanding of how to create and apply access control lists (ACLs).ĮAP support must be enabled on the RADIUS server. The device must have a RADIUS configuration and be connected to the Cisco secure access control server (ACS). IEEE 802.1X must be enabled on the device port. The following tasks must be completed before implementing the IEEE 802.1X Port-Based Authentication feature: Prerequisites for Configuring IEEE 802.1X Port-Based Authentication

Navigator to find information about platform support and Cisco software image Which each feature is supported, see the feature information table. The features documented in this module, and to see a list of the releases in Release notes for your platform and software release. May not support all the features documented in this module. This feature supports both access ports and trunk ports. The switch functions are provided by either built-in switch ports or a plug-in module with switch ports. The device can combine the function of a router, switch, and access point, depending on the fixed configuration or installed modules. IEEE 802.1X port-based authentication is configured on a device to prevent unauthorized devices (supplicants) from gaining access to the network.
