2. Refer to the following read-only information on each listed QoS policy to determine whether an
existing policy can be used as is, an existing policy requires edit or a new policy requires
creation:
NOTE
When using a wireless client classification other than WMM, only legacy rates are supported on that
WLAN.
3. Either select the Add button to define a new WLAN QoS policy, or select an existing WLAN QoS
policy and select Edit to modify its existing configuration. Existing QoS policies can be selected
and deleted as needed.
A Quality of Service (QoS) policy screen displays for the new or selected WLAN. The screen
displays the WMM tab by default, but additional tabs also display for WLAN and wireless
client rate limit configurations. For more information, refer to the following:
• Configuring a WLAN’s QoS WMM Settings
• Configuring Rate Limit Settings
• Configuring Multimedia Optimizations
WLAN QoS Policy Displays the name assigned to this WLAN QoS policy when it was initially created. The assigned
policy name cannot be modified as part of the edit process.
Wireless Client
Classification Lists each policy’s Wireless Client Classification as defined for this WLAN's intended traffic. The
Classification Categories are the different WLAN-WMM options available to a radio. Classification
types include:
WMM – Implies WiFi Multimedia QoS extensions are enabled on this radio. This allows different
traffic streams between the wireless client and the Access Point to be prioritized according to the
type of traffic (voice, video etc). WMM classification is required to support the high throughput data
rates required of 802.11n device support.
Voice – Optimized for voice traffic. Implies all traffic on this WLAN is prioritized as voice traffic on
the radio.
Video – Optimized for video traffic. Implies all traffic on this WLAN is prioritized as video traffic on
the radio.
Normal – Optimized for best effort traffic. Implies all traffic on this WLAN is prioritized as best effort
traffic on the radio.
Low – Optimized for background traffic. Implies all traffic on this WLAN is low priority on the radio.
Non-Unicast – Optimized for non-Unicast traffic. Implies all traffic on this WLAN is designed for
broadcast or multicast.
SVP Prioritization A green check mark defines the policy as having Spectralink Voice Prioritization (SVP) enabled to
allow the wireless controller to identify and prioritize traffic from Spectralink/Polycomm phones
using the SVP protocol. Phones using regular WMM and SIP are not impacted by SVP prioritization.
A red “X” defines the QoS policy as not supporting SVP prioritization.
WMM Power Save Enables support for the WMM based power-save mechanism, also known as Unscheduled
Automatic Power Save Delivery (U-APSD). This is primarily used by voice devices that are WMM
capable. The default setting is enabled.
Multicast Mask Primary Displays the primary multicast mask defined for each listed QoS policy. Normally all multicast and
broadcast packets are buffered until the periodic DTIM interval (indicated in the 802.11 beacon
frame), when clients in power save mode wake to check for frames. However, for certain
applications and traffic types, the administrator may want the frames transmitted immediately,
without waiting for the DTIM interval. By configuring a primary and secondary multicast mask, an
administrator can indicate which frames are transmitted immediately. Setting masks is optional
and only needed if there are traffic types requiring special handling.
Multicast Mask Secondary Displays the secondary multicast mask defined for each listed QoS policy.
