Apple iOS device mark QoS as per IETF recommendations. With WLC running AireOS 8.3, you can enable the Fastlane feature, which enables several beneficial functions:
- Your WLC QoS configuration is optimized globally to better support real-time applications
- Requirements WLC running AireOS 8.3 and higher, devices running iOS 10 and higher. Components Used Conventions iOS 10 devices can send upstream voice traffic without the requirement to perform WMM TSPEC/TCLAS negotiation. The infrastructure will honor the voice marking for these devices.
- You can apply a QoS profile to your iOS 10 devices, and decide which applications should receive QoS marking upstream, and which applications should be sent as best effort or background.
