The Configuring 802.1x Port Based Authentication module provides you with the instructions and Cisco hardware to develop your hands on skills in configuring port based authentication. This module contains the following exercises:

  • Enable and configure 802.1x port based authentication on a port on the router
  • Configure a switch to act as a 802.1x port based authentication supplicant
  • Observe the negotiation process of these two devices

Exercise 1 - Enable and Configure Port Based Authentication for a Single Client

Port based authentication provides a security mechanism to allow or disallow connectivity to a device connected to a specific port. The device attempting to connect to such a port is called a supplicant. The supplicant can be an end user device, such as a computer or an IP telephone, or it can be another network device.

In this exercise you will enable and configure port based authentication on the NYEDGE1 router. You will then configure the NYCORE1 switch to authenticate as a supplicant on the specific port on the router.

Before you begin, make sure that the PLABCSCO01 server is on as it will be pinged to determine the state of the authenticated port.
