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)

To ensure end-to-end QoS and preserve markings correctly in the VoWLAN setup, the configurations needed on the wired network are trust boundaries and policy maps. Trust boundaries define where the network trusts the QoS markings on packets, and policy maps are used to enforce QoS policies on the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The feature required on the Cisco Wireless LAN Controller to support dynamic VLAN mapping is AAA override. This feature allows for the assignment of VLANs on a per-user basis as determined by the authentication, authorization, and accounting server. When AAA override is enabled, attributes such as VLAN ID can be dynamically applied to a user’s session after successful authentication and authorization. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

To enable VLAN tagging for wireless Identity-Based Networking on a WLAN, an engineer must enable AAA override, which allows for dynamic VLAN assignment. Additionally, the RADIUS server attributes need to be updated to include tunnel type 64, medium type 65, and tunnel private group type 81, which are necessary for VLAN tagging information. 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)

When using FlexConnect Smart AP Image Upgrade without a configured FlexConnect Master AP, the WLC will transfer the image to one indoor AP and one outdoor AP separately. Each AP model needs a different firmware image due to hardware differences. Therefore, there will be two image transfers from the WLC: one for the 2702i APs and another for the 1532i APs.

The Voice VLAN feature on switches allows the network to distinguish between voice traffic and data traffic from wireless clients connected to IP phones. This is crucial for applying the appropriate QoS to ensure that voice traffic is prioritized over client data traffic. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.

 LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and maintaining distributed directory information services over an IP network. In the context of Cisco ISE (Identity Services Engine), LDAP can be utilized as a directory service to authenticate and authorize users during local web authentication processes. LDAP supports a wide range of directory services, including Microsoft Active Directory, which is commonly used in enterprise environments.
