Traffic Management (QoS)
Changing the Protocol that Prioritizes Traffic and Enabling
Admission Control
As discussed earlier, when you enable WMM, wireless devices queue frames
according to QoS marks. The default protocol for the QoS mark is 802.1p.
However, you can change the protocol to DSCP by accessing advanced WMM
parameters.
Another advanced WMM parameter is admission control, a feature available
for Video and Voice queues. The more stations that use high priority settings,
the less effect those settings have. Admission control restricts the number of
stations in a wireless cell that can use the high priority settings by forcing
stations to check with the RP first.
To configure these advanced options, follow these steps:
1. Select Network Setup > WLAN Setup and click the WMM tab.
As you can see in Figure 4-56, the WMM enabled column displays the
WLANs for which you have set the Access Category to Automatic/WMM.
