Figure 5-1. Switch with 802.1x Network Access Control If a user, or supplicant, attempts to communicate via the switch on any interface except interface 1/g1, the system challenges the supplicant for login credentials. The system encrypts the provided information and transmits it to the RADIUS server. If the RADIUS server grants access, the system sets the 802.1x port state of the interface to authorized and the supplicant is able to access network resources. console(config)#radius-server host 10.10.10.10 console(Config-radius)#exit console(config)#radius-server key secret console(config)#exit console#show radius-servers IP address Type Port TimeOut Retran.
