Usage Guidelines
You must globally enable IEEE 802.1x on the switch by using the dot1x system-auth-control global
configuration command before enabling IEEE 802.1x on a specific port.
The IEEE 802.1x protocol is supported on Layer 2 static-access ports and voice VLAN ports.
You can use the auto keyword only if the port is not configured as one of these:
•
•
•
78-16882-01
dot1x port-control {auto | force-authorized | force-unauthorized}
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 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 on a dynamic 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 dynamic, an error message
appears, and the port mode is not changed.
Dynamic-access ports—If you try to enable IEEE 802.1x on a dynamic-access (VLAN Query
Protocol [VQP]) port, an error message appears, and IEEE 802.1x is not enabled. If you try to
change an IEEE 802.1x-enabled port to dynamic VLAN assignment, an error message appears, and
the VLAN configuration is not changed.
