Messages related to 802.1X operation
Message	Meaning
Port <port-list> is not an authenticator.	The ports in the port list have not been enabled as 802.1X authenticators. Use this command to enable the ports as authenticators: switch(config)# aaa port-access authenticator e 10
Port <port-list> is not a supplicant.	Occurs when there is an attempt to change the supplicant configuration on a port that is not currently enabled as a supplicant. Enable the port as a supplicant and then make the desired supplicant configuration changes. See Enabling a Switch Port as a Supplicant..
No server(s) responding.	This message can appear if you configured the switch for EAP-RADIUS or CHAP-RADIUS authentication, but the switch does not receive a response from a RADIUS server. Ensure that the switch is configured to access at least one RADIUS server. (Use `show radius`.) If you also see the message Can’t reach RADIUS server <x.x.x.x>, try the suggestions listed for that message.
LACP has been disabled on 802.1X port(s).	To maintain security, LACP is not allowed on ports configured for 802.1X authenticator operation. If you configure port security on a port on which LACP (active or passive) is configured, the switch removes the LACP configuration, displays a notice that LACP is disabled on the ports, and enables 802.1X on that port.
Error configuring port <port-number>: LACP and 802.1X cannot be run together.	Also, the switch will not allow you to configure LACP on a port on which port access (802.1X) is enabled.
