The QoS policy is applied under the WLAN configuration. The SSID policy is applied as shown in the following
example. This results in “trusted” behavior for traffic ingressing from wireless, similar to wired.

This explains the capabilities of QoS that are available on the Cisco Catalyst 3850. On the egress (downstream),
QoS capabilities exist per access point, radio, SSID, and client.
Policy on Access Point/Port
The ports that are connected to access points are termed wireless ports throughout this document. There are four
queues on the wireless ports to match the four queues on the access point. The queue structure is 2P2Q3T: two
priority queues, and two SRR queues, with three thresholds each. The recommended queuing configuration in a
2P2Q3T structure is shown in Figure 7.
Figure 7. 2P2Q3T Queue Model for Queuing Application Traffic
Four queues are created at the port level when a port is configured as a wireless port: real time 1 (RT1), RT2,
unicast non real time (NRT), and multicast nonclient NRT.
The multicast nonclient is classified as any traffic that has a destination IP address of multicast or broadcast.
