QoS Mode MSS supports Layer 2 and Layer 3 classification and marking of traffic, to help provide end-to-end QoS throughout the network. The following modes of QoS are supported:

„Wi-Fi Multimedia (WMM)—Provides wireless QoS for time-sensitive applications such as voice and video. WMM QoS is enabled by default and does not require any configuration.

„SpectraLink Voice Priority (SVP)—Provides optimized forwarding of SVP voice traffic. SVP QoS is disabled by default.

Session-based Call Admission Control (CAC) is also supported. You can use CAC with either QoS mode to ensure bandwidth availability by limiting the number of active sessions a radio can have.
