On the Global Configuration page of a Wireless LAN Controller (WLC), for an Access Point (AP) to use IEEE 802.1X for authenticating to the wired infrastructure, it is necessary to configure a RADIUS shared secret. This secret will be used by the AP as part of its credentials when communicating with a RADIUS server during the authentication process. References: (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 For a BYOD setup using a dual SSID approach, the first SSID is typically used for device registration and the second for network access. Setting the NAC State to Radius NAC enables the network access control (NAC) to use RADIUS for authentication, authorization, and accounting. Allowing AAA Override enables the RADIUS server to dynamically change the VLAN and ACLs assigned to the endpoint, which is crucial for BYOD where devices need to be placed into the correct VLAN based on user role and device type. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, particularly the chapters on BYOD and advanced WLAN configuration.

The remote LAN (RLAN) feature on the OfficeExtend Access Point (OEAP) is used to extend the wired network through more than one port. This allows the creation of a wired interface on the OEAP that can be associated with a specific VLAN, providing connectivity for wired devices at remote locations. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

During the Extensible Authentication Protocol (EAP) process, the RADIUS server generates an encrypted session key after the client’s identity is authenticated. This session key is sent to the access point to encrypt data frames between the client and the access point. It ensures that each session has a unique encryption key, enhancing security. References: Look for information on EAP and RADIUS in the CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

When deploying Cisco Hyperlocation, it is important to enable the feature on both the wireless LAN controller and Cisco CMX to ensure proper functionality and data accuracy. Additionally, if the Cisco CMX server is a VM, a high-end VM is required to handle the processing demands of Cisco Hyperlocation deployments. References: The considerations for deploying Cisco Hyperlocation are covered in the certification guide, which emphasizes the importance of enabling the feature on both the controller and CMX, as well as the hardware requirements for the CMX server.

The primary change to the network when adding APs for location-based services, such as VolMLAN, would be the AP footprint. This refers to the physical coverage area of the access points. Increasing the AP footprint enhances the ability to perform location-based services by improving the accuracy of triangulation and location tracking of devices. This is because a denser AP footprint allows for more precise determination of a device’s location within the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing location-based services and AP deployment strategies for optimal coverage and location tracking.
