2.2.2.4 AP Association Table
A wireless access point responder uses this data object to report the wireless hosts that are associated with it. This information is particularly useful for discovering legacy wireless devices that do not implement the responder. Additionally, it allows the mapper to conclusively match wireless hosts that are associated with the same access point via different BSSIDs (for example, one for each supported band).
The table MUST contain 0 or more entries for associated stations, where each entry MUST have the following format.

MAC_address_of_wireless_host (6 bytes): MAC address of the particular 802.11 station that is associated with the AP.
Max_Oper_Rate (2 bytes): The maximum operational data rate at which the selected radio can run to the given host, in network byte order. The data rate MUST be encoded in units of 0.5 Mbps.
PHY_type (1 byte): The physical medium type for the given host. Valid values are defined in section 2.2.1.1.21.
Reserved (1 byte): MUST be set to zero when sent and MUST be ignored on receipt.

If the size of the actual AP Association Table exceeds 409 entries, the responder MUST make only 409 entries available in this data object. It is up to the implementer to choose which stations to make available in that case.
