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

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

Enabling unicast AP multicast mode can correct the issue of increased controller CPU overhead and overall network utilization after multicast is enabled. This mode allows the controller to send multicast traffic to the APs as unicast, which is more efficient for the wireless medium and reduces the load on the controller’s CPU.

To take full advantage of the WLAN configuration, VoWLAN phones must support 802.11e, which is a standard for wireless QoS, and Wi-Fi Multimedia (WMM), which is a subset of 802.11e that provides prioritized media delivery. These standards ensure that voice traffic is prioritized appropriately in the wireless network. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)
