4-54WS5100 Series Switch System Reference Guide

WMM enabled	Displays WLAN-WMM status. It can be enabled (for a WLAN) from the WLAN
	Configurations Edit screen by selecting the Enable WMM checkbox.
Access	Displays the Access Category for the intended radio traffic. The Access Categories are the
	different WLAN-WMM options available to the radio.
	The four Access Category types are:
	•	Background — Optimized for background traffic
	•	Best-effort — Optimized for best effort traffic
	•	Video — Optimized for video traffic
	•	Voice — Optimized for voice traffic
AIFSN	Displays the current Arbitrary Inter-frame Space Number (AIFSN). Higher-priority traffic
	categories should have lower AIFSNs than lower-priority traffic categories. This will causes
	lower-priority traffic to wait longer before trying to access the medium.
Transmit Ops	Displays the maximum duration a device can transmit after obtaining a transmit opportunity.
	For Higher-priority traffic categories, this value should be set higher.
CW Min	The CW Min is combined with the CW Max to make the Contention screen. From this range,
	a random number is selected for the back off mechanism. Lower values are used for higher
	priority traffic.
CW Max	The CW Max is combined with the CW Min to make the Contention screen. From this range,
	a random number is selected for the back off mechanism. Lower values are used for higher
	priority traffic.
