Chapter 11 Configuring QoS in a Wireless Environment
QoS Configuration Examples
Beginning in privileged EXEC mode, follow these steps to adjust the CW-min and CW-max settings:
Use the no form of the command to reset the setting to defaults.
QoS Configuration Examples
These sections describe two common uses for QoS:
• Giving Priority to Voice Traffic, page 11-9
• Giving Priority to Video Traffic, page 11-10
Giving Priority to Voice Traffic
This section demonstrates how you can apply a QoS policy to your wireless network.
In this example, the network administrator creates a policy named voice_policy that applies voice class
of service to traffic from packets having Priority precedence in IP Precedence field. The user applies the
voice_policy to the incoming and outgoing radio ports and to the outgoing Ethernet port. Figure 11-3
shows the administrator’s QoS Policies page.

Step 3
traffic-class class
{ cw-min number }
{ cw-max number }
{ fixed-slot number }
Assign CW-min, CW-max, and fixed-slot settings to a traffic
class. Use the values in Table 11-2 to enter settings that provide
the best performance for your network configuration.
Note If packet concatenation is enabled, you need to adjust
the CW-min and CW-max settings only for traffic class
0. Concatenation is enabled by default.
