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

When a wireless controller is configured to authenticate clients against Microsoft Active Directory using PEAP (Protected Extensible Authentication Protocol), it uses RADIUS (Remote Authentication Dial-In User Service) as the protocol to communicate with the authentication server. RADIUS is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

 The customizable security report in Cisco Prime Infrastructure that shows rogue access points (APs) detected since a point in time is the “New Rogue APs” report. This report is specifically designed to track and list all newly detected rogue APs within the network from a specified time, allowing network administrators to quickly identify unauthorized devices. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )

 FlexConnect is a wireless solution for branch office and remote office deployments. It allows APs to switch client data traffic locally and perform client authentication locally when they are disconnected from the WLC. For WLAN A to work in FlexConnect mode and WLAN B to work in local mode, the APs need to be part of a FlexConnect group with proper WLAN-VLAN mappings. This ensures that the correct VLAN is used for each WLAN, which is essential when the APs are operating in FlexConnect mode. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The correct command to configure the controller to update Cisco CMX every 5 seconds for rogue devices is “config nmsp notification interval rssi rogues 5”. NMSP (Network Mobility Services Protocol) is used by Cisco wireless controllers to manage and communicate with connected services such as Cisco CMX. The command structure “config nmsp notification interval” followed by the specific type of device or metric, in this case, ‘rssi rogues’, and the desired interval time ‘5’ seconds, sets the frequency of NMSP notifications for RSSI updates related to rogue devices.

 Cisco AVC (Application Visibility and Control) on a Cisco Wireless LAN Controller (WLC) is used to prioritize traffic by marking the packets. For Cisco IP cameras that use the wireless network, the AVC rule would be configured to mark the packets with a specific QoS value, ensuring that the video traffic is treated with higher priority as it traverses the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To rename access points and add them to the correct AP groups on a wireless controller, the minimum custom attributes required using Cisco ISE TACACS is role1=WIRELESS. This role provides the necessary permissions for read/write access to wireless-related configurations. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

To create an account for CLI access to an access point for troubleshooting, the WLC must be configured to allow user access with the capability to make changes. The ReadWrite User Access Mode enables an engineer to have full read and write access to the AP’s configuration via the CLI, which is necessary for performing troubleshooting tasks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

The AAA override feature on a WLAN allows for individualized security policies to be applied to users after they are authenticated by the AAA server, which in this case is Cisco ISE (Identity Services Engine). The company policy requires that all users be denied access to any resources until they pass validation. By using AAA override, the network can enforce access control policies based on user credentials and group membership, ensuring that users cannot access network resources until they have been validated by Cisco ISE. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

 For a wireless network supporting voice and video applications for Apple devices, especially with Fastlane implementation, the QoS profile to configure on the user WLAN for iPhones updated to version 14.5.432302546 is Platinum. This profile provides the highest level of QoS, ensuring priority for voice and video traffic. References:= (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)
