Although the preceding policy shows its shaping, it does not buffer or smooth out the rate. Essentially this is a rate

limiter at radio level.

Policy on Service Set Identification

Policy at SSID level or at BSSID level is user configurable in both upstream and downstream directions. SSID-level

policies are applied in the WLAN configuration mode.

In downstream direction, the recommended policy is a hierarchical queuing policy with table-map-based marking in

the parent class default. In absence of a table-map configuration in the SSID, the packets are all remarked down to

0. The packets are sent through the NRT queue at the port level. This is because the WLAN is considered to be

untrusted in the absence of a table-map.

If voice/video traffic needs to be prioritized, the child policy-maps on both the port/access point and SSID should be

configured with class-maps and appropriate actions. If the child policy for voice/video differentiation is missing on

either one of the targets (port/access point and/or SSID), the voice and video traffic will not be prioritized on the

wireless network.

The following is an example of two SSIDs: enterprise and guest. The voice/video traffic is prioritized on the

enterprise, while the guest traffic is classified as default and given the appropriate queuing treatment.
