Controller Based WLANs

How to configure WMM Traffic Shaping Policy for WMM clients?
Requirement:
Aruba Controller running 6.3.x.x and above.


Solution:
Wi-Fi uses a shared medium and is used by many different client types and applications. So, fair access to send data becomes critically important, especially during times of high contention amongst multiple clients. First, it is important that all clients receive access to that medium when they have data to transmit and at the same time we need to make sure that the media traffic is prioritized to avoid media loss.
 
Quality of service (QoS) is a set of packet markings and queuing mechanisms that prioritize classes of traffic through the network. It is a system for marking traffic as higher priority and adjusting the packet timers to allow delay-sensitive data to have precedence on the air. Streams that are commonly designated for special treatment include voice and video streams, where bandwidth, packet loss, jitter, and latency must all be controlled.


Configuration:
WMM Traffic Shaping Policy profile has to be configured and mapped to the VirtualAP profile.
Please find the below CLI commands to configure WMM Traffic Management Policy:
(Aruba7210) #configure terminal
Enter Configuration commands, one per line. End with CNTL/Z

1.) Enable bandwidth shaping policy:
(Aruba7210) (config) #wlan wmm-traffic-management-profile default
(Aruba7210) (WMM Traffic management profile "default") #enable-shaping

2.)Configure the percentage for specified categories:
(Aruba7210) (WMM Traffic management profile "default") #background 5
(Aruba7210) (WMM Traffic management profile "default") #best-effort 10
(Aruba7210) (WMM Traffic management profile "default") #best-effort 5
(Aruba7210) (WMM Traffic management profile "default") #video 20
(Aruba7210) (WMM Traffic management profile "default") #voice 30
(Aruba7210) (WMM Traffic management profile "default") #!

3.) Map the configured WMM Traffic Shaping Policy to VAP:
(Aruba7210) (config) #wlan virtual-ap default
(Aruba7210) (Virtual AP profile "default") #wmm-traffic-management-profile default
(Aruba7210) (Virtual AP profile "default") #!
(Aruba7210) (config) #
Please find the steps to configure WMM Traffic Shaping Policy via GUI:
1.) Login to controller GUI and Navigate to Configuration > Advanced Services > All Profiles.
2.) Click on QoS  and navigate to WMM Traffic Management> Create new profile as below.
