Cisco 300-430 - Implementing Cisco Enterprise Wireless Networks (300-430 ENWLSI)

The issue with the Cisco CMX dashboard not showing any data can be resolved by integrating the Wireless LAN Controllers (WLCs) with the CMX system. The CMX solution relies on data from the WLCs to track and detect users’ presence in the office area. Without the WLCs being added to CMX, the system cannot collect the necessary analytics and location data for its operations.

To segregate iOS devices to the guest SSID on VLAN 101 and distribute the rest of the clients on VLAN 102, creating a service template and enabling device classification are required. The service template specifies the VLAN assignment, while device classification identifies the type of device connecting to the network. References: Cisco Catalyst 9800-80 WLC documentation on local policies and device classification.

To address concerns about detecting spurious threats from channels not used by the wireless infrastructure, deploying APs in monitor mode (B) and local mode with WIPS submode (D) would be beneficial. Monitor mode allows APs to listen to the wireless spectrum and identify potential threats, while WIPS (Wireless Intrusion Prevention System) submode enhances the ability to detect and mitigate wireless threats. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

On a Cisco Catalyst 9800 Series Wireless Controller, the command set that prevents a FlexConnect AP from allowing wireless clients to connect when its Ethernet connection is nonoperational is the fallback-radio-shut command within the FlexConnect profile configuration. This command disables the radios on the AP, thus preventing client connections during Ethernet link failure. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

In a historic building where adding APs is challenging, the best approach to implement intrusion protection with a focus on on-channel attacks is to use APs in monitor mode with the Wireless Intrusion Prevention System (WIPS) submode. This setup allows the APs to dedicate their time to scanning the environment for threats without serving clients, which is suitable given the adequate coverage and the need to monitor for attacks. 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.

For printing services using Bonjour in a WLAN environment where mDNS services are utilized, especially with WLC firmware version 8.x, it’s essential that:

Enable mDNS and IGMP snooping (Option A): Multicast DNS or mDNS needs to be enabled for Bonjour services to function correctly as they rely on this protocol for service discovery within local networks. IGMP snooping improves network efficiency by ensuring multicast traffic is only forwarded to nodes that have explicitly requested it.

For location analytics in a shopping center using AireOS controllers with Cisco Wave 2 APs, the CMX server settings must exclude probing clients to track only associated clients. This setting ensures that the location analytics data reflects the movements of clients that are actively connected to the WLAN, providing accurate insights into popular areas within the shopping center. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 The issue described indicates that the Angle of Arrival (AoA) data is not being transmitted between the Cisco Wireless LAN Controller (WLC) and the virtual CMX server. To resolve this, the network administrator must ensure that port 2003 is allowed for AoA packets to flow through between the CMX appliances, which is necessary for Hyperlocation data transmission. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 To prevent honeypot attacks most efficiently, the wireless network engineer should set the auto containment level to 4 and select the Using Our SSID containment option (D). This configuration allows the system to automatically contain rogue APs that are spoofing the organization’s SSID, which is a common tactic in honeypot attacks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.
