taken into account and the chosen AC is the highest resulting from L2 and L3. If only one of the priority
tags is present, it is used to select the queue. If none is present, the default queue AC_BE is chosen.
NOTE
If the wireless packets to be transmitted must include the L2 priority (send to a WMM client from a WMM-enabled
AP), the outbound L2 priority is copied from the inbound L2 priority if available, or it is inferred from the L3 priority
using the above table if the L2 inbound priority is missing.

Configuring the QoS policy on a WM-AD
The following is an overview of the steps involved in configuring the QoS on a WM-AD.
Step one - Define the QoS mode to employ on the WM-AD:
z Legacy - Enables DL (downlink) classification for all clients
z WMM:
z Enables WMM support
z Enables DL classification for WMM clients
z Enables UL (uplink) classification in WMM clients
z 802.11e:
z Enables 802.11e support
z Enables DL classification for 802.11e clients
z Enables UL classification in 802.11e clients
WMM and 802.11e are similar but, they use different signaling (same as WPA and WPA2).
Step 2 - Enabling Turbo Voice:
z Ensures WM-AD is optimized for voice performance and capacity
z Can be enabled or disabled on individual WM-ADs
z If Turbo Voice is enabled, together with QoS modes Legacy, WMM, or 802.11e, DL voice traffic is
sent via Turbo Voice queue instead of voice queue. A separate turbo voice queue allows for some
