Traffic Management (QoS)
Customizing How QoS Marks Map to ACs
As discussed earlier, enabling WMM on a WLAN allows wireless devices to queue
traffic according to either an 802.1p or DSCP. Table 4-9 shows the default mapping
of values to priority queues.
Table 4-9. Priority Values for WMM ACs
The mapping of priority value to AC occurs as traffic is prepared for transmission in
a WLAN. For traffic traveling the opposite direction—from the WLAN to the
Ethernet—the Wireless Edge Services zl Module reverses the operation, marking
traffic that arrives in a particular AC with a priority value.
You can change the mapping to customize your network’s queues. Follow these steps:
1. Select Network Setup > WLAN Setup and click the WMM tab.
2. Click the QoS Mappings button. The QoS Mappings screen is displayed.
