Mapping from 802.1p, WMM user priority to CoS is static. Also, mapping from CoS to access category (AC) on the APs
is static.
Table 4 shows how WMM priority information is mapped across the network.

QoS mode

WSS Software 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.
