802.1X port security configuration
Enabling 802.1X port security
By default, 802.1X port security is disabled on Brocade devices. To enable the feature on the
device and enter the dot1x configuration level, enter the following command.
device and enter the dot1x configuration level, enter the following command.
Brocade(config)# dot1x-enable
Brocade(config-dot1x)#
Brocade(config-dot1x)#
Syntax: [no] dot1x-enable
At the dot1x configuration level, you can enable 802.1X port security on all interfaces at once, on
individual interfaces, or on a range of interfaces.

For example, to enable 802.1X port security on all interfaces on the device, enter the following
command.

Brocade(config-dot1x)# enable all
Syntax: [no] enable all
To enable 802.1X port security on interface 1/3/11, enter the following command.
Brocade(config-dot1x)# enable ethernet 1/3/11
Syntax: [no] enable ethernet port
Specify the port variable in stack-unit/slotnum/portnum format.
To enable 802.1X port security on interfaces 1/3/11 through 1/3/16, enter the following

Setting the port control
To activate authentication on an 802.1X-enabled interface, you specify the kind of port control to
be used on the interface. An interface used with 802.1X port security has two virtual access
points: a controlled port and an uncontrolled port:
be used on the interface. An interface used with 802.1X port security has two virtual access
points: a controlled port and an uncontrolled port:
•
The controlled port can be either the authorized or unauthorized state. In the authorized state,
it allows normal traffic to pass between the Client and the Authenticator. In the unauthorized
state, no traffic is allowed to pass.

The uncontrolled port allows only EAPOL traffic between the Client and the Authentication
Server.
Server.
for an illustration of this concept.
By default, all controlled ports on the device are in the authorized state, allowing all traffic. When
you activate authentication on an 802.1X-enabled interface, its controlled port is placed in the
unauthorized state. When a Client connected to the interface is successfully authenticated, the
controlled port is then placed in the authorized state. The controlled port remains in the authorized
state until the Client logs off.
