Usage Guidelines You must globally enable IEEE 802.1x authentication on the switch by using the dot1x
system-auth-control global configuration command before enabling IEEE 802.1x authentication on a
specific port.
The IEEE 802.1x standard is supported on Layer 2 static-access ports, voice VLAN ports, and Layer 3

no dot1x port-control
Enable IEEE 802.1x authentication on the port and cause the port to change to
the authorized or unauthorized state based on the IEEE 802.1x authentication
exchange between the switch and the client.
Disable IEEE 802.1x authentication on the port and cause the port to transition
to the authorized state without an authentication exchange. The port sends and
receives normal traffic without IEEE 802.1x-based authentication of the client.
unauthorized state, ignoring all attempts by the client to authenticate. The
switch cannot provide authentication services to the client through the port.
Modification
This command was introduced.
Trunk port—If you try to enable IEEE 802.1x authentication on a trunk port, an error message
appears, and IEEE 802.1x is not enabled. If you try to change the mode of an IEEE 802.1x-enabled
port to trunk, an error message appears, and the port mode is not changed.
Dynamic ports—A port in dynamic mode can negotiate with its neighbor to become a trunk port. If
you try to enable IEEE 802.1x authentication on a dynamic port, an error message appears, and
IEEE 802.1x authentication is not enabled. If you try to change the mode of an IEEE 802.1x-enabled
port to dynamic, an error message appears, and the port mode is not changed.
