Configuring the Quality of Service
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 141
4
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.
This section describes how to configure the WAN, LAN, and WLAN QoS. It
includes the following topics:
• General QoS Settings, page 141
• Configuring the WAN QoS, page 141
• Configuring the LAN QoS, page 147
• Configuring the Wireless QoS, page 150
General QoS Settings
STEP 1 Click Networking -> QoS -> General Settings.
The General Settings window opens.
STEP 2 Enter the following information:
• WAN QoS: Check this box to enbale the WAN QoS feature. By default, WAN
QoS is disabled.
• LAN QoS: The LAN QoS specifies priority values that can be used to
differentiate the traffic and give preference to higher-priority traffic, such as
telephone calls. Check this box to enbale the LAN QoS feature. By default,
LAN QoS is disabled.
• Wireless QoS: The Wireless QoS controls priority differentiation for data
packets in wireless egress direction. Check this box to enbale the Wireless
QoS feature. By default, Wireless QoS is disabled.
STEP 3 Click Save to apply your settings.
Configuring the WAN QoS
This section describes how to configure the WAN QoS settings. It includes the
following topics:
• Managing the WAN Bandwidth for Upstream Traffic, page 142
