Configuring Quality of Service

The Quality of Service (QoS) feature is applied throughout the network to ensure that network traffic is prioritized according to required criteria and that the desired traffic receives preferential treatment.

QoS guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP, online games, and IPTV, since these applications are delay sensitive and often require a fixed bit rate.

Refer to the following topics:

•General QoS Settings, page 155

•Configuring WAN QoS, page 156

•Configuring LAN QoS, page 166

•Configuring Wireless QoS, page 169

•Understanding DSCP Values

General QoS Settings

Use the General Settings page to enable or disable the WAN QoS, LAN QoS, and WLAN QoS features.

STEP 1 Click Networking > QoS > General Settings.

STEP 2 Enter the following information:

•WAN QoS: Check this box to enable WAN QoS. By default, WAN QoS is disabled.

•LAN QoS: Check this box to enable LAN QoS. LAN QoS specifies priority values that can be used to differentiate traffic and give preference to higher-priority traffic, such as telephone calls. By default, LAN QoS is disabled.

•Wireless QoS: Check this box to enable Wireless QoS. Wireless QoS controls priority differentiation for data packets in wireless egress direction. By default, Wireless QoS is disabled. The wireless QoS only applies to the ISA550W and ISA570W.
