Chapter 13 Configuring QoS Configuring QoS • The Ethernet upstream flow is traffic sent from the bridge Ethernet port to a switch or router on the wired LAN. The bridge does not prioritize traffic that it sends to the wired LAN based on traffic classification. Precedence of QoS Settings When you enable QoS, the bridge queues packets based on the Layer 2 class of service value for each packet. The bridge applies QoS policies in this order: 1. Packets already classified-When the bridge receives packets from a QoS-enabled switch or router that has already classified the packets with non-zero 802.1Q/P user_priority values, the bridge uses that classification and does not apply other QoS policy rules to the packets. An existing classification takes precedence over all other policies on the bridge. 2. Policies you create on the bridge-QoS Policies that you create and apply to VLANs or to the bridge interfaces are second in precedence after previously classified packets. 3. Default classification for all packets on VLAN-If you set a default classification for all packets on a VLAN, that policy is third in the precedence list. Note Because client devices cannot associate to the bridge, the QoS element for wireless phones setting is not supported on the bridge. Configuring QoS QoS is disabled by default. This section describes how to configure QoS on your bridge. It contains this configuration information: • Configuration Guidelines, page 13-3 • Configuring QoS Using the Web-Browser Interface, page 13-4 • Adjusting Radio Traffic Class Definitions, page 13-8 Configuration Guidelines Before configuring QoS on your bridge, you should be aware of this information: • The most important guideline in QoS deployment is to be familiar with the traffic on your wireless LAN. If you know the applications used by wireless client devices, the applications' sensitivity to delay, and the amount of traffic associated with the applications, you can configure QoS to improve performance. • QoS does not create additional bandwidth for your wireless LAN; it helps control the allocation of bandwidth. If you have plenty of bandwidth on your wireless LAN, you might not need to configure QoS. OL-4059-01 Cisco Aironet 1400 Series Wireless Bridges Software Configuration Guide 13-3
