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)

Split tunneling on a Cisco Aironet 600 Series OfficeExtend AP allows for traffic to be divided between two different networks. In this case, it enables the user to access the corporate network for work-related tasks while simultaneously allowing them to print to a printer on their home network. This is achieved by routing the traffic meant for the corporate network to the WLC, while local traffic such as the connection to a home printer is kept on the local network. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

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.

The command cmxha convert backup is used on the backup Cisco CMX server to designate it as the secondary server in a high-availability deployment. This command helps to resolve the issue where both servers are considered primary. References: Cisco CMX high-availability documentation will provide more details on this command.

The Simple Certificate Enrollment Protocol (SCEP) is used to securely issue certificates to network devices in a scalable manner. When provisioning certificates on a Cisco Catalyst 9800 Series Wireless Controller using a third-party CA server, SCEP is the protocol that facilitates this process. It allows the controller to request and install certificates automatically, which is essential for establishing secure communications within the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The feature that must be enabled to ignore non-802.11 interference is “Avoid Persistent Non-WiFi Interference.” This setting allows the Radio Resource Management (RRM) to not react to non-802.11 noise and interference, which can be crucial in environments where such interference is common but does not significantly impact wireless performance. By enabling this feature, RRM will not change the channel in response to non-IEEE 802.11 interferers, thus maintaining a stable channel plan. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

In Quality of Service (QoS) for networking, Class of Service (COS) and Differentiated Services Code Point (DSCP) are used for traffic classification and prioritization. Voice traffic is generally given high priority due to its sensitivity to delay and requires proper tagging to maintain quality over the network.

The correct mapping for voice traffic, according to best practices, is a COS value of 5 mapped to a DSCP value of 46. This is because DSCP 46 corresponds to Expedited Forwarding (EF), which is typically used for voice traffic prioritization in IP networks.

The exhibit shows the output from a command on a network device that displays the current mappings between COS values and DSCP values. The mapping that needs modification for correct voice traffic tagging can be identified by looking at the standard practice for voice QoS, which uses a COS value of 5 mapped to a DSCP value of 46.

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.
