LABEL	DESCRIPTION
QoS	Select the Quality of Service priority for this BSS’s traffic.
	• If you select WMM from the QoS list, the priority of a data packet depends on the
	packet’s IEEE 802.1q or DSCP header. If a packet has no WMM value assigned to
	it, it is assigned the default priority.
	• If you select WMM_VOICE, WMM_VIDEO, WMM_BESTEFFORT or
	WMM_BACKGROUND, the NWA applies that QoS setting to all of that SSID’s
	traffic.
	• If you select None, the NWA applies no priority to traffic on this SSID.

	Note: When you configure an SSID profile’s QoS settings, the NWA applies the same
	QoS setting to all of the profile’s traffic.

	Packets coming from the WLAN using this SSID profile are tagged with the VLAN ID
