 Application Visibility and Control (AVC) profiles in AireOS controllers allow the identification and management of bandwidth consumption by different applications. By using AVC, administrators can set policies to prioritize or restrict bandwidth for specific applications, thus ensuring that critical services like voice and video are not adversely affected by bandwidth-heavy programs. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The default IEEE 802.1x AP authentication configuration on a Cisco Catalyst 9800 Series Wireless Controller is EAP-FAST with CAPWAP DTLS (Option D). This method uses EAP-FAST for authentication within a secure tunnel established by Datagram Transport Layer Security (DTLS) over CAPWAP, which provides both security for authentication credentials and encryption for wireless management frames. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

The absence of rogue AP options in the navigation menu under Maps in Cisco Prime Infrastructure (PI) version 3.0 indicates that there is an issue with integrating location services, which are provided by Mobility Services Engine (MSE). Without adding MSE to PI, location-based services such as tracking rogue access points cannot be utilized or displayed within PI’s interface. 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.

Disabling DHCP proxy on the Cisco WLC and running the ip helper-address command under the VLAN interface to point to DHCP and the two ISE servers is the recommended action. This allows direct communication between clients and DHCP/ISE servers, which is necessary for accurate device profiling.

Protocol Independent Multicast (PIM) sparse mode and dense mode are two different multicast routing mechanisms. Sparse mode uses distribution trees and is designed for networks where multicast groups are sparsely distributed across the network, minimizing unnecessary traffic. In contrast, dense mode floods the network with multicast traffic and then prunes back the branches where there are no interested receivers, which can lead to inefficient use of bandwidth. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 The issue described occurs when the fallback feature is disabled on the Cisco AireOS controller. When fallback is disabled, the controller does not attempt to reconnect to the primary TACACS+ server after it becomes available again following a failure. Instead, it continues to use the secondary server until it fails or the controller is rebooted. Enabling fallback would allow the controller to periodically attempt to reconnect to the primary server. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

When an MSE with wIPS service is installed, it is crucial for alarm information to reach the MSE from the controllers. The Network Mobility Services Protocol (NMSP) is the protocol that facilitates this communication. Ensuring that NMSP is allowed through any firewalls or network security devices is essential for the proper functioning of the wIPS service. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )
