Table 17 Network > Wireless LAN > QoS
LABEL DESCRIPTION
Enable WMM QoS Use WMM QoS (Wifi MultiMedia Quality of Service) to give different
types of traffic different priorities. The PLA450 assigns priority to
packets based on the 802.1q or DSCP information in their headers.
If a packet has no WMM information in its header, it is assigned the
default priority. See Section 6.4.1 on page 63 for more information.
WMM QoS Policy Select Default to have the PLA450 automatically give voice and
video traffic priority so their services operate more smoothly. The
PLA450 gives a service a priority level according to the ToS value
in the IP header of packets it sends.
Select
