Traffic Management (QoS)
5. If you are using DSCP to prioritize traffic in at least one WLAN, configure
the QoS mappings in the DSCP to Access Category section.
To select the AC to which a particular DSCP maps, click the Access
Category column in the row for that value. Then choose Best Effort, Back-
ground, Video, or Voice from the drop-down menu.
6. Click the OK button.
Manually Classifying a WLAN’s Traffic
By default, the Wireless Edge Services xl Module and RPs treat traffic destined
to stations in any WLAN equally. However, you can manually assign all traffic
in a particular WLAN to a specific AC. Traffic then receives QoS according to
the relative priority of that AC. For example, you could configure a WLAN for
traditional data traffic and a WLAN for voice traffic. To prioritize traffic sent
to the voice wireless devices, you would manually set the entire voice WLAN
to the Voice AC.
Note With WMM, RPs automatically prioritize different types of traffic. Enabling
WMM on a WLAN also allows WMM-capable stations to prioritize traffic
automatically according to QoS values. See “WMM” on page 4-92 and
“Enabling WMM on a WLAN” on page 4-96.
To set a WLAN’s AC manually, follow these steps:
1. Access the Edit screen for the WLAN:
a. Select Network Setup > WLAN Setup and click the Configuration tab.
b. Select the WLAN and click the Edit button. The Edit screen is displayed.
