Local Area Networks (WLANs)” and Chapter 3: “Radio Port Configuration.”
WLAN Classification
WMM allows RPs to queue frames according to priority marking. Alternatively,
RPs can place all traffic that is destined to stations associated with a particular
WLAN in the same queue. The four queues are the same as the four access
categories (ACs) for WMM (Voice, Video, Best Effort, and Background), and
the RPs use the same parameters for transmitting traffic in those queues that
they would use for WMM. The only difference is that traffic is queued statically
according to WLAN instead of automatically according to priority marking.
Voice Prioritization
Voice prioritization improves QoS for traffic destined to VoWLAN devices.
When you enable this feature in a WLAN, RPs monitor frames received from
stations in that WLAN. When a voice frame is detected, the Wireless Edge
Services zl Module marks all traffic destined to the source of that frame for
priority handling.
Ethernet devices between the Wireless Edge Services zl Module and the RP
and the RP itself place return traffic to the VoWLAN device in a high-priority
queue. Thus, voice prioritization can improve QoS for voice traffic in both the
Ethernet and the wireless networks.
