Configuring The Qos Policy On A Wm-Ad - Extreme Networks Summit WM20 User Manual

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 1 – Define the QoS mode to employ on the WM-AD:
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 2 – Enabling Turbo Voice:
Ensures WM-AD is optimized for voice performance and capacity
●
Can be enabled or disabled on individual WM-ADs
●
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
WM-ADs to use the Turbo Voice parameters for voice traffic, while other WM-ADs 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.
Step 3 – Defining the DSCP and service class classifications:
All 64 DSCP code-points are supported. The IETF defined codes are listed by name and code. Un-
defined codes are listed by code. The following is the default DSCP service class classification:
