Figure 3 Interactions involved in guest access
W-ClearPass Guest is part of your network’s core infrastructure and manages guest access to the network.
NAS devices, such as wireless access points and wired switches on the edge of the network, use the RADIUS
protocol to ask W-ClearPass Policy Manager to authenticate the username and password provided by a guest
logging in to the network. If authentication is successful, the guest is then authorized to access the network.
Roles are assigned to a guest as part of the context W-ClearPass Policy Manager uses to apply its policies.
RADIUS attributes that define a role’s access permissions are contained within Policy Manager’s Enforcement
Profile. Additional features such as role mapping for W-ClearPass Guest can be performed in W-ClearPass
Policy Manager.
The network usage of authorized guests is monitored by the NAS and reported in summary form to W-
ClearPass Policy Manager using RADIUS accounting, which allows administrators to generate network reports
in W-ClearPass Insight.
