Local Profiling on Cisco WLC

BD.

Local profiling on a Cisco Wireless LAN Controller (WLC) running AireOS is a feature that allows the WLC to identify and classify wireless clients based on their behavior, device type, and operating system, among other factors. This information is then used to enforce network access policies and apply appropriate Quality of Service (QoS) settings.

The following two statements about local profiling on a Cisco WLC running AireOS are true:

A. Profiling is performed on IPv4 and IPv6 clients.

This statement is true. The local profiling feature on a Cisco WLC running AireOS can identify and classify both IPv4 and IPv6 wireless clients, including mobile devices, laptops, and IoT devices. The profiling process analyzes various attributes of the client, such as the MAC address, hostname, DHCP option values, and User-Agent string, to determine the device type, OS version, and other relevant information.

D. Profiling is performed only on IPv4 clients.

This statement is false. As mentioned above, local profiling on a Cisco WLC running AireOS can identify and classify both IPv4 and IPv6 wireless clients, not just IPv4 clients.

B. Wired clients behind the workgroup bridge are not profiled and no policy action is taken.

This statement is true. Wired clients connected to a switch behind a workgroup bridge (WGB) are not directly visible to the WLC and are not profiled or subject to policy enforcement. This is because the WGB acts as a layer 2 bridge and does not forward client information to the WLC. However, if the wired client sends traffic through the WGB to the wireless network, it may be profiled and subjected to policy enforcement based on its wireless behavior.

C. Wired clients behind the workgroup bridge are profiled and a policy action is taken.

This statement is false. As mentioned above, wired clients behind a WGB are not profiled or subject to policy enforcement because they are not visible to the WLC. Only wireless clients that associate with an access point (AP) managed by the WLC can be profiled and subjected to policy enforcement.

E. When local profiling is enabled, RADIUS profiling is allowed.

This statement is false. Local profiling and RADIUS profiling are two different methods of identifying and classifying wireless clients. Local profiling is performed by the WLC itself, while RADIUS profiling involves sending client information to a RADIUS server for analysis and classification. Enabling local profiling does not automatically enable RADIUS profiling, although the two methods can be used together to provide more comprehensive client profiling.
