6.15 Configuring the QoS policy on a VNS
The following is an overview of the steps involved in configuring the QoS on a
VNS.
Step one – Define the QoS mode to employ on the VNS:
• Legacy – Enables DL (downlink) classification for all clients
•WMM:
• Enables WMM support
• Enables DL classification for WMM clients
• Enables UL (uplink) classification in WMM clients
• 802.11e:
• Enables 802.11e support
• Enables DL classification for 802.11e clients
• Enables UL classification in 802.11e clients
WMM and 802.11e are similar but, they use different signaling (same as WPA
and WPA2).
Step two – Enabling Turbo Voice:
• Ensures VNS is optimized for voice performance and capacity
• Can be enabled or disabled on individual VNSs
• 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 VNSs to use the
Turbo Voice parameters for voice traffic, while other VNSs use the voice
parameters for voice traffic.
• If WMM mode is also enabled, WMM clients use Turbo Voice-like
contention parameters for UL voice traffic.
• If 802.11e mode is also enabled, 802.11e clients use Turbo Voice-like
contention parameters for UL voice traffic.
