Wireless Local Area Networks (WLANs)
Traffic Management (QoS)
A green check mark in the WLAN Enabled column indicates that RPs in your
network currently support this WLAN; a green check mark in the WMM
Enabled column indicates that RPs are allowed to send the WMM parameters
to stations (Access Category is Automatic/WMM.) In Figure 4-58, four WLANs
are active and enabled. However, only two (MyWLAN and Test) implement
WMM prioritization on wireless station to RP traffic.
The final four columns list the station WMM parameters for the queue in this
row. The default settings grant lower latency for the queues with higher
numbers.
Typically, no further configuration is necessary. You only need to know that
by accepting these settings from the RPs, wireless stations can improve QoS
for certain types of traffic.
For example, if a wireless station is transmitting a voice frame, the station will
compete for the radio using the advantageous settings that the RP has speci-
fied for such frames. However, the station must meet these requirements for
the prioritization to take effect:
■ The station must support WMM.
■ The traffic must be marked by an application on the wireless station for
the higher AC.
Customizing Station WMM Parameters
If you have a great deal of experience working with WMM and other QoS
protocols, you can customize the queue settings to the needs of your
environment.
Note Because the Wireless Edge Services zl Module automatically defines settings
such that traffic in a higher-priority queue receives lower latency, the default
station WMM parameters settings are usually adequate. Also, because incor-
rect settings can adversely affect network performance, ProCurve Network-
ing generally recommends that you do not change these parameters.
To customize station WMM parameters, complete these steps:
1. Select Network Setup > WLAN Setup and click the WMM tab.
