Figure 4-53. Using WMM to Prioritize Traffic Transmitted from RPs to Wireless
Stations
Priority Queuing on Traffic Transmitted from Wireless Stations to
RPs. Only when you enable WMM on a WLAN, WMM-enabled stations also
implement priority queuing on traffic they transmit.
RPs broadcast station WMM parameters throughout the WLAN. WMM-
enabled stations queue traffic according to 802.1p or DSCP value, using the
WMM parameters to determine how to handle traffic in each queue. (Non-
WMM stations continue to handle all traffic normally.) Figure 4-54 illustrates
the affect of WMM on wireless station to RP traffic.
