6.2 Configuring WLAN QoS Policies

Wireless LAN Policy
QoS provides a data traffic prioritization scheme. QoS reduces congestion from excessive traffic. If there is
enough bandwidth for all users and applications (unlikely because excessive bandwidth comes at a very high
cost), then applying QoS has very little value. QoS provides policy enforcement for mission-critical
applications and/or users that have critical bandwidth requirements when bandwidth is shared by different
users and applications.
QoS helps ensure each WLAN receives a fair share of the overall bandwidth, either equally or as per the
proportion configured. Packets directed towards clients are classified into categories such as Management,
Voice and Data. Packets within each category are processed based on the weights defined for each WLAN.
The Quality of Service screen displays a list of QoS policies available to WLANs. Each QoS policy has its own
radio button that can be selected to edit its properties. If none of the exiting QoS policies supports an ideal
QoS configuration for the intended data traffic of this WLAN, select the Add button to create new policy.
Select the radio button of an existing WLAN and select Ok to map the QoS policy to the WLAN displayed in
the banner of the screen.
Use the WLAN Quality of Service (QoS) Policy screen to add a new QoS policy or edit the attributes of an
existing policy.
1. Select Configuration > Wireless > WLAN QoS Policy to display existing QoS policies available to
WLANs.

NOTE: WLAN QoS configurations differ significantly from QoS policies configured for
radios. WLAN QoS configurations are designed to support the data requirements of
wireless clients, including the data types they support and their network permissions.
Radio QoS policies are specific to the transmit and receive char act is tics of the
connected radio’s themselves, independent from the wireless clients these access point
radios support.
