Connecting to Cisco ISE

Context

Connecting to Cisco ISE refers to using the Cisco ISE server for authentication and authorization on a network admission control (NAC) network. NAC is a type of E2E security architecture that covers 802.1X, MAC, and portal authentication, and supports configuration of aggregation and access layers. NAC enables authentication, authorization, and accounting for device administrators and access users, ensuring device and network security.

Procedure

  1. Choose Configuration > Advanced Services > Connecting to Cisco ISE. The configuration page is displayed.
  2. On the Select Authentication Interfaces page, select interfaces for authentication configuration by performing any of the following operations based on actual requirements:

    • Click an interface icon to select an interface. You can click the icon again to deselect the interface.
    • Drag the mouse to select continuous interfaces in batches.
    • Click multiple interface icons to select them. You can click a certain icon again to deselect the interface.

    After selecting an interface, click Clear Interface Authentication Configuration to clear the original authentication configuration of the interface.

  3. To clear all authentication configurations on the device, click Clear Authentication Configuration.
  4. Set the Authentication method to 802.1X, MAC, or Portal.
  5. Set the Network layer to Aggregation layer or Access layer.

    NOTE:

    Network layer is configurable only when the Authentication method is set to 802.1X.

  6. Specify the parameters in Authentication Configuration, .

    NOTE:

    Authentication Configuration is not supported when the Authentication method is set to 802.1X and the Network layer is set to Access layer.
