802.1X Configuration

Introduction to 802.1X and EAP

The 802.1X IEEE standard defines port-based, authenticated network access control for Ethernet local area networks (LANs). With 802.1X, the user or device must pass network access control by successfully authenticating with credentials, such as a name and password, or network access is denied. 802.1X uses the Extensible Authentication Protocol (EAP) to relay port access requests between LAN stations/the clients being authenticated (supplicants), Ethernet switches or wireless access points (authenticators) and RADIUS servers (authentication servers).

EAP is the standard authentication mechanism carried over 802.1X. The EAP method is an inner authentication protocol that provides the secure mechanism for the authentication exchange. Multiple EAP methods can be used. EAP methods are defined in International Engineering Task Force (IETF) Requests for Comments (RFC) documents, RFC drafts, or they can be proprietary. EAP methods have a significant influence on how your network is designed and implemented, because not all supplicants, not all access points, and not all RADIUS servers support all EAP methods. A careful evaluation of standards can help with selecting appropriate LAN components that will avoid vendor lock-in or dead-end technology.

802.1X Configuration in CentreWare IS

Use the 802.1X configuration pages in CentreWare IS to perform the following tasks. Required information varies depending on the EAP method(s) that you select.

Note: Access to the 802.1x configuration pages in CentreWare IS can be restricted by the passwords and feature authorization settings under Administrative Security.

1.Launch your web browser.

2.Enter the printer’s IP address in the browser’s Address field.

3.Click Properties.

4.Open the Security folder on the left navigation panel and select 802.1X.

5.Click the Advanced button for more experienced users or click the Configuration Wizard button which will guide you through the setup.

For more information, click the Help button in CentreWare IS to view the online help.

6.Select EAP authentication method(s) – Select one or more authentication methods:

■MD5 Challenge

■TLS

■PEAP-MS-CHAPv2 (PEAP)

If you select a method that uses X.509 security certificates (TLS or PEAP), you can use use a root certificate to validate the authenticating server's certificate.

If you select TLS authentication, you must either install a signed device certificate that is trusted by the authenticating server, or add the device's self-signed certificate to the authenticating server's trusted certificate store.

1235DT, 1235/DX, 4510 specifications

The Xerox 4510 and 4250 are robust monochrome laser printers designed to cater to the needs of modern office environments. Known for their reliability and impressive output quality, these models excel in providing high-performance solutions for businesses seeking efficiency and productivity.

The Xerox 4510 is renowned for its ability to deliver exceptional print speeds of up to 65 pages per minute (ppm). This allows organizations to meet high-volume printing demands without compromising on quality. Its maximum monthly duty cycle of up to 300,000 pages makes it suitable for busy workplaces, reducing the need for frequent maintenance and ensuring uninterrupted operations. In contrast, the Xerox 4250 offers a slightly lower printing speed of 50 ppm, making it an ideal option for small to medium-sized businesses that require consistent performance without excessive output.

Both printers are equipped with advanced print resolution capabilities, delivering sharp text and detailed graphics at up to 1200 x 1200 dpi. This ensures that every document produced meets professional standards, making them perfect for presentations, reports, and correspondence. The user-friendly interface allows for seamless navigation and operation, further enhancing productivity in the workplace.

A significant feature of these models is their support for versatile media types and sizes. They can handle a variety of paper weights and dimensions, accommodating everything from standard letter-sized paper to envelopes and labels. This flexibility makes them suitable for diverse printing tasks and varied business needs.

In terms of technology, both printers utilize Xerox's state-of-the-art imaging technology, which contributes to their high-quality output and reliability. The inclusion of automatic duplex printing is another standout feature, allowing users to print on both sides of the paper, thus reducing paper consumption and environmental impact.

Connectivity is another strong point for the Xerox 4510 and 4250. They are equipped with various connectivity options, including USB, Ethernet, and wireless capabilities. This ensures easy integration into existing office networks, allowing multiple users to access the printer simultaneously.

In summary, the Xerox 4510 and 4250 printers embody exceptional performance, quality, and versatility, making them valuable assets for any office environment. Their advanced technologies, high-speed capabilities, and user-friendly features position them as trusted solutions for businesses aiming to enhance their printing efficiency while maintaining high standards of output.
