CAUTION: Use caution when changing the 802.1X authentication settings. You might lose the connection. If

communication with the device is lost, you might need to reset the device server to a factory-default state, and

then reinstall the device.

For most 802.1X networks, the infrastructure components, such as LAN switches, must use 802.1X protocols to

control a port's access to the network. If these ports do not allow partial or guest access, you might need to

congure the print server with the 802.1X parameters prior to connecting to the network. To congure the initial

802.1X settings before connecting to the network, you can use an isolated LAN or a direct computer connection

using a crossover cable. The supported 802.1X authentication protocols and associated conguration depend on

the print server model and rmware version.

Use the following steps to congure this option:

1. Select the supported protocols that are used for 802.1X authentication on the network.

●

PEAP (congure certicate rst): Protected Extensible Authentication Protocol (PEAP) uses digital

certicates for network server authentication and passwords for client authentication. PEAP requires

an EAP user name, EAP password, and Certicate Authority (CA) certicate. Dynamic encryption keys

are also used.

●

EAP-TLS (congure certicate rst): Extensible Authentication Protocol using Transport Layer Security

(EAP-TLS) is a mutual authentication protocol based on digital certicates for authentication of the

client and network server. EAP-TLS requires an EAP user name, HP Jetdirect certicate, and CA

certicate. Dynamic encryption keys are also used.

2. In the User name text box, enter the EAP/802.1X user name for the device (maximum of 128 characters).

The default user name is the default hostname of the print server, NPIxxxxxx, where xxxxxx is the last six

digits of the LAN hardware (MAC) address.

3. In the Password text box, enter the EAP/802.1X password for the device (maximum of 128 characters).

4. In the Conrm password text box, enter the password again.

5. In the Server ID text box, enter the server ID that identies and validates the authentication server. The

server ID is specied on the digital certicate that a trusted CA issued for the authentication server.

NOTE: If the Require Exact Match checkbox is not selected, you can specify any string for the server ID.

6. To validate the server ID that is specied in the Server ID box against the server ID that is specied in the

digital certicate issued by the CA for the authentication server, select the Require Exact Match checkbox.

7. In the On Authentication Failure section, select one of the following options:

●

Connect Anyway (802.1x Fail-over): If this option is selected and the 802.1X authentication settings

are applied to an unsecured port, the device does not lose connectivity if you do not change from an

unsecured port to a secured port on the device. The device connectivity functions without 802.1X

authentication.

●

Block Network (Secure failure): If this option is selected and the 802.1X authentication settings are

applied to an unsecured port, the device enters a communication error status if you do not change

from an unsecured port to a secured port on the device. To return the device to a ready state, change

to a secured port on the device.

8. From the Encryption strength list, select the level of encryption for the selected protocols.

Federal Information Processing Standard (FIPS) supports only the High encryption strength. To congure

the encryption strength when FIPS mode is enabled on the device, you must specify the High encryption

strength. If you specify the Low or Medium encryption strength, the conguration fails.

9. To initialize the port, select the Re-authenticate on apply checkbox. The device re-authenticates the 802.1X

settings after they are applied.
