300-430 Cisco Exam Lab Questions

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 image provided shows a packet capture with multiple entries displaying UDP traffic between two IP addresses using different ports (notably port number ‘16666’ which is commonly used for NMSP). Network Mobility Services Protocol (NMSP) is used by wireless controllers like WLCs to communicate with management software such as Cisco’s Mobility Services Engine or CMX. This protocol helps in managing various mobility services across wireless networks. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide

Trusting DSCP is essential for maintaining the QoS markings across the wired and wireless network in a FlexConnect deployment. By trusting DSCP, the WLC and APs will preserve the QoS markings set by applications and devices, ensuring consistent QoS treatment throughout the network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

The configuration required is to trust the DSCP (Differentiated Services Code Point) on the controller switch port. This ensures that the voice traffic’s class of service is maintained throughout the network. By trusting DSCP, the switch will preserve the DSCP value set by the wireless LAN controller, which is responsible for marking the voice packets. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.
