This document describes techniques to handle Quality of Service (QoS) on a Cisco Wireless LAN Controller
(WLC) and the infrastructure devices to which the controller connects. QoS for Cisco wireless products is an
often overlooked area that becomes more critical with the increase in data rates.

The QoS checklist is a quick guide that explains how to set up QoS correctly. Subsequent sections of this
document explain settings and other information about wired networks, so that wireless QoS can be fully
realized.

If you are familiar with QoS terms and wireless technology, start with the checklist; otherwise, read the
explanations first.

If you are familiar with wired QoS but not with wireless QoS, be sure to read the explanations on Wi-Fi
Multimedia (WMM) in order to understand why wireless QoS is much more critical than wired QoS.

Expand WLANs, and click the QoS tab.

1. 

For each WLAN, choose Allowed from the WMM Policy drop-down list .

2. 

For each WLAN, choose the appropriate QoS level from the Quality of Service (QoS) drop-down list:

Choose Platinum  for wireless VoIP comunications with other types of traffic.

♦ 

Choose Gold only for video streaming networks with no voice traffic.

♦ 

Choose Silver for all general purpose data networks with no voice or video traffic.

♦ 

Choose Bronze for all guest networks.
