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, Background, 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 zl 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 4-90 and “Enabling WMM on a
WLAN” on page 4-94.
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.
