dot1x control-direction
Use the dot1x control-direction interface configuration command to configure the IEEE 802.1x
authentication with the wake-on-LAN (WoL) feature to configure the port control as unidirectional or
bidirectional. Use the no form of this command to return to the default setting.

Usage Guidelines Use the both keyword or the no form of this command to return to the default setting, bidirectional
mode.
For more information about WoL, see the “Using IEEE 802.1x Authentication with Wake-on-LAN”
section in the “Configuring IEEE
802.1x Port-Based Authentication” chapter in the software
configuration guide.
Examples This example shows how to enable unidirectional control:
Switch(config-if)# dot1x control-direction in
These examples show how to enable bidirectional control:
Switch(config-if)# dot1x control-direction both
You can verify your settings by entering the show dot1x all privileged EXEC command.
The show dot1x all privileged EXEC command output is the same for all switches except for the port
names and the state of the port. If a host is attached to the port but is not yet authenticated, a display
similar to this appears:
Supplicant MAC 0002.b39a.9275
AuthSM State = CONNECTING
BendSM State = IDLE
PortStatus = UNAUTHORIZED
in Enable bidirectional control on port. The port cannot receive
packets from or send packets to the host.
both Enable unidirectional control on port. The port can send packets to
the host but cannot receive packets from the host.
