QoS Configuration Examples These sections describe two common uses for QoS: • Giving Priority to Voice Traffic, page 13-10 • Giving Priority to Video Traffic, page 13-12 Giving Priority to Voice Traffic This section demonstrates how you can apply a QoS policy to your wireless network's voice VLAN to give priority to wireless phone traffic. In this example, the network administrator creates a policy named voice_policy that applies voice class of service to traffic from Spectralink phones (protocol 119 packets). The user applies the voice_policy to the incoming and outgoing radio ports and to the outgoing Ethernet port for VLAN 77. Figure 13-3 shows the administrator's QoS Policies page. 13-10 Cisco Aironet 1400 Series Wireless Bridges Software Configuration Guide OL-4059-01
