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 specified 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 incorrect settings can
adversely affect network performance, ProCurve Networking 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.
