Application Visibility and Control (AVC) profiles must be implemented to remark the QoS value for WebEx traffic. AVC profiles allow the network to identify different applications and provide the appropriate QoS treatment, ensuring high-quality meetings.  References  := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

 IGMP snooping is a feature that allows a network switch to listen to the Internet Group Management Protocol (IGMP) network traffic. This feature enables the switch to identify the multicast streams to which hosts are interested and to forward multicast traffic intelligently. By enabling IGMP snooping on the Wireless LAN Controller (WLC), it ensures that multicast streams are only forwarded to the access points (APs) where clients are subscribed to them. Setting the AP multicast mode to a specific multicast address, such as 238.255.255.255, allows the WLC to send multicast traffic to APs using this address, which helps in efficient distribution of the multicast stream.

Cisco Connected Mobile Experiences (CMX) Location Analytics requires accurate tracking of devices within the wireless network’s coverage area. To utilize CMX Location Analytics effectively, it is essential to enable tracking parameters in Cisco Mobility Services Engine (MSE). This allows MSE to collect data on device locations and movements within the environment, which can then be analyzed by CMX for insights into customer behavior, asset tracking, or other analytical purposes.  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.

The Extensible Authentication Protocol (EAP) is an authentication framework frequently used in wireless networks and Point-to-Point connections. During the EAP authentication process,  EAP Request  and  EAP Response  packets are exchanged between the supplicant (client device) and the authenticator (network). These packets are used to transport messages for the authentication process. An  EAP Request  packet is sent by the authenticator requesting identity information from the supplicant, while an  EAP Response  packet is sent by the supplicant in reply to the request. The other options, such as EAP complete, EAP failure, and EAP reply, are not standard EAP packet types.  References : CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

If the Cisco 5520 Series Wireless LAN Controller is no longer manageable via the network after implementing a CPU ACL, permit statements must be added to the top of the ACL in both directions (A). These statements should specify the network from which management is allowed and the virtual interface of the controller to ensure proper management access.  References : CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To separate different types of client authentication on a Cisco ISE deployment, policy sets and policy groups can be used. Policy sets allow the creation of policies based on conditions such as device type, while policy groups categorize clients for the application of specific policies.  References : Cisco ISE documentation on policy sets and policy groups will have detailed information.
