set radio-profile wmm-powersave

Enables Unscheduled Automatic Powersave Delivery (U-APSD) on AP radios managed by the radio profile. U-APSD enables WMM clients that use powersave mode to more efficiently request buffered unicast packets from AP radios.

When U-APSD is enabled, a client can retrieve buffered unicast packets for a traffic priority enabled for U- APSD by sending a QoS data or QoS-Null frame for that priority. U-APSD can be enabled for individual traffic priorities, for individual clients, based on the client’s request. A client enables U-APSD for a traffic priority by indicating this preference when (re)associating with the AP radio.

A client can but is not required to request U-APSD for all four traffic priorities. The AP radio still buffers packets for all traffic priorities even if the client does not request U-APSD for them. However, to retrieve buffered packets for priorities that are not using U-APSD, a client must send a separate PSpoll for each buffered packet.
