Description (partial)

Symptom:
Traffic with a DSCP value of AF21, AF22, or AF23 (equivalent to binary IP Precedence of 010, "Immediate") experiences delays. Ping response times to a local gateway may slow to around 500 - 1000 ms when DSCP is set to those values, but response times are much faster with other DSCP values (typically 5 - 20 ms).

Conditions:
WAP571 receives traffic with QoS applied, and the DSCP value is AF21, AF22, or AF23.
