Quality of Service
Quality of service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics.
The controller supports four QoS levels:
Platinum/Voice—Ensures a high quality of service for voice over wireless.
Gold/Video—Supports high-quality video applications.
Silver/Best Effort—Supports normal bandwidth for clients. This is the default setting.
Bronze/Background—Provides the lowest bandwidth for guest services.
VoIP clients should be set to Platinum.
You can configure the bandwidth of each QoS level using QoS profiles and then apply the profiles to WLANs. The profile settings are pushed to the clients associated to that WLAN. In addition, you can create QoS roles to specify different bandwidth levels for regular and guest users. Follow the instructions in this section to configure QoS profiles and QoS roles. You can also define the maximum and default QoS levels for unicast and multicast traffic when you assign a QoS profile to a WLAN.
The wireless rate limits can be defined on both upstream and downstream traffic. Rate limits can be defined per SSID and/or specified as a maximum rate limit for all clients. These rate limits can be individually configured.
