Item Description
WEP — Enterprise Select WEP — Enterprise security if your network uses WEP with EAP/802.1x
authentication. This type of security utilizes a central authentication server, such as
RADIUS, to authenticate users on the network. For WEP — Enterprise, the HP Jetdirect
print server supports these server-based authentication protocols: LEAP PEAP EAP-
TLS. Provide the following if you select WEP — Enterprise:
●
Authentication — (Read only) Set to Open. Open system authentication does not
require authentication for network access. (Your network might use WEP
encryption keys for data security.)
●
Enabled Protocols : Select LEAP, PEAP, or EAP-TLS. LEAP (Lightweight
Extensible Authentication Protocol) is a proprietary protocol from Cisco Systems
that uses passwords for mutual authentication (the client and the server
authenticate each other). PEAP (Protected Extensible Authentication Protocol) is a
mutual authentication protocol that uses digital certificates for server authentication
and passwords for client authentication. For additional security, the authentication
exchanges are encapsulated within TLS (Transport Level Security). EAP-TLS (EAP
using Transport Level Security) is a mutual authentication protocol based on digital
certificates.
●
User Name : Enter an EAP/802.1X user name, which cannot exceed 128
characters, for this device. The default user name is the default host name of the
print server, NPIxxxxxx, where xxxxxx are the last six digits of the LAN hardware
(MAC) address.
●
Password and Confirm Password : Enter an EAP/802.1X user password (up to
128 characters) for this device and then confirm the password by entering it again.
●
Server ID : Specify the Server ID validation string identifying and validating the
authentication server. This string is specified on the digital certificate issued by a
trusted Certificate Authority (CA) for the authentication server. The entry can be a
partial string unless you select
Require Exact Match .
●
Encryption Strength : Specify the minimum encryption strength to use during
communications with the authentication server. You can select Low, Medium, or
High encryption strength. For each encryption strength, ciphers are specified to
identify the weakest cipher allowed.
●
Jetdirect Certificate : A self-signed HP Jetdirect certificate is preinstalled and used
to validate the identity of the HP Jetdirect device to clients and to network
authentication servers. This allows the HP Embedded Web Server to use HTTPS
and appear as a secure site when accessed by a Web browser. Click
Configure to
update the certificate or install a new one.
●
CA Certificate : To validate the authentication server's identity, a CA (or Root)
certificate must be installed on the print server. This CA certificate must be issued
by the Certificate Authority who signed the authentication server's certificate. Click
Configure to configure or install a CA certificate.
●
Authentication Behavior : Control authentication when you click Apply on this
page, assuming valid configuration entries were made.
If Reauthenticate on Apply is not selected (the default), the print server does not
attempt re-authentication unless configuration changes cause the print server to
disconnect and reconnect to the network. If selected, the print server always
attempts to re-authenticate using the configuration values.
