Chapter 2 Catalyst 3550 Switch Cisco IOS Commands

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.
Syntax Description
in
both
Defaults
The port is in bidirectional.
Command Modes Interface configuration
Command History Release
12.2(25)SEC
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
OL-8566-02
dot1x control-direction {in | both}
no dot1x control-direction {in | both}
Modification
This command was introduced.
Enable bidirectional control on port. The port cannot receive
packets from or send packets to the host.
Enable unidirectional control on port. The port can send packets to
the host but cannot receive packets from the host.
