The figure above shows a complete wired plus wireless solution. The NAC and posture examples in Chapters 3, 4, and 5 can be used independently or they can work in unison for a complete solution.
At the center of the access management system, is the W-ClearPass Policy Manager. The ClearPass Policy Manager is a comprehensive policy management solution that can secure next-generation mobility services, enhance network access security and compliance and streamline network operations for wired, wireless, and virtual private network (VPN) environments. Specific network access privileges can be based on user role, device type, health of endpoint, time-of-day and more.
The W-ClearPass OnGuard application works with the Policy Manager to enable advanced posture assessments. OnGuard also performs health checks of the devices that are on the network, or that request access to the network. OnGuard can be used as a persistent client application, or a dissolvable client (for example, a client that does not require permanent installation) that is used at the time of network access.
This section covers the Dell EMC PowerSwitch, W-series controllers, and access points used for this solution.
The N-series is a family of energy-efficient and cost-effective 1 GbE, and 10 GbE switches designed for modernizing and scaling network infrastructure. The variety of models and options, including PoE+, makes the N-series switches an optimal choice for access switches in any campus environment.
Radius CoA enables W-ClearPass OnGuard to detect changes in posture and automatically enforce policies without the need to force a disconnect. This allows the user to maintain connectivity while issues with their device are assessed. Dell Networking N-Series Firmware Version v6.2, introduced this key feature to enable a better NAC and posture assessment with W-ClearPass OnGuard. This document contains examples validated using firmware version 6.2.6.6.
N-series switches capable of running the v6.2.6.6 firmware include:

W-Series wireless networking products include a wide variety of solutions to enable wireless networking access. Controller-based products offer high performance, fully featured solutions to satisfy any size business. Controller-less W-Instant Access Point (W-IAP) products offer many of the same features in a simple to use and affordable solution. Both controller-based and W-IAP solutions offer integration with W-ClearPass for unmatched access and policy control of wireless devices.
