AP能力查询和AP能力报告消息使Multi-AP Controller或Multi-AP Agent能够获取Multi-AP设备上所有AP radio的能力信息。
If triggered, a Multi-AP Controller or a Multi-AP Agent shall send an AP Capability Query message per section 17.1.6. If a Multi-AP Agent receives an AP Capability Query message, then it shall respond within one second with an AP Capability Report message per section 17.1.7. A Multi-AP Agent shall include one AP Capability TLV in the AP Capability Report message. A Multi-AP Agent shall include one AP Radio Basic Capabilities TLV for each AP radio in the AP Capability Report message. A Multi-AP Agent that implements Profile-2 shall include one Metric Collection Interval TLV in the AP Capability Report message.
如果被触发，则Multi-AP控制器或Multi-AP代理应根据第17.1.6节发送AP能力查询消息。 如果一个Multi-AP代理收到一个AP能力查询消息，则它应根据17.1.7节在一秒钟内以一个AP能力报告消息做出响应。 Multi-AP代理应在AP能力报告消息中包含一个AP能力TLV。 一个Multi-AP代理应在AP能力报告消息中为每个AP无线电包括一个AP无线电基本能力TLV。 实现Profile-2的Multi-AP代理应在AP能力报告消息中包含一个度量标准收集间隔TLV。
If an AP radio supports 802.11 High Throughput capability, a Multi-AP Agent shall include an AP HT Capabilities TLV for that radio in the AP Capability Report message. If an AP radio supports 802.11 Very High Throughput capability, a Multi-AP Agent shall include an AP VHT Capabilities TLV for that radio in the AP Capability Report message. If an AP radio supports 802.11 High Efficiency capability, a Multi-AP Agent shall include an AP HE Capabilities TLV for that radio in the AP Capability Report message.
如果AP无线电支持802.11高吞吐量能力，则Multi-AP代理应在AP能力报告消息中包括该无线电的AP HT能力TLV。 如果AP无线电支持802.11非常高吞吐量能力，则Multi-AP代理应在AP能力报告消息中包括该无线电的AP VHT能力TLV。 如果AP无线电支持802.11高效率功能，则Multi-AP代理应在AP能力报告消息中包括该无线电的AP HE能力TLV。
If an AP radio managed by a Multi-AP Agent is capable of multiple virtual radio operation (see Table 1), then the Multi-AP Agent shall identify each of the virtual radios separately with a unique Radio unique identifier in the capabilities TLVs and indicate capability information only pertaining to indicated virtual radio in the capabilities TLVs in the AP Capability Report message.
如果由Multi-AP Agent管理的APradio能够进行多种虚拟VAP操作（请参阅表1），则Multi-AP代理应在能力TLV中使用唯一的无线电唯一标识符分别识别每个虚拟无线电，在AP能力报告消息中的能力TLV中指示虚拟VAP有关的能力信息。
If a Multi-AP Agent that implements Profile-2 sends an AP Capability Report message, it shall perform the following:
如果实现Profile-2的Multi-AP代理发送了AP能力报告消息，则它应执行以下操作：
• Include one Channel Scan Capabilities TLV in the AP Capability Report message. Operating classes specified in this TLV shall be 20 MHz operating classes from Table E-4 of [1]. If the "On boot only" bit is set to one, the Scan Impact field shall be set to 0x00.
•在“ AP功能报告”消息中包括一个通道扫描功能TLV。 该TLV中规定的工作类型应为表E-4【1】规定的20 MHz工作模式。 如果“On boot only”位设置为1，则“Scan Impact”字段应设置为0x00。
• Include one CAC Capabilities TLV in an AP Capabilities Report message. A Multi-AP Agent may restrict its reported CAC capabilities to match the regulations of the country in which it is operating. The CAC Capabilities TLV shall include an indication of the country in which the Multi-AP Agent is operating according to the two letter codes provided in [6]. The Multi-AP Agent shall specify CAC capabilities for each Simultaneous CAC Radio in the Multi-AP Agent.
•在“ AP功能报告”消息中包括一个CAC功能TLV。 Multi-AP代理可能会限制其报告的CAC功能以匹配其运营所在国家/地区的法规。 CAC能力TLV应包含根据[6]中提供的两个字母代码对Multi-AP代理进行操作的国家/地区的指示。 Multi-AP代理应为Multi-AP代理中的每个同时CAC radio指定CAC能力。
• Include one Profile-2 AP Capability TLV in the AP Capability Report message.
•在“ AP能力报告”消息中包括一个Profile-2 AP能力TLV。
If a Multi-AP Agent that implements Profile-2 sends a Profile-2 AP Capability TLV, it shall perform the following:
如果实现Profile-2的Multi-AP Agent发送Profile-2 AP能力TLV，则它应执行以下操作：
• Set the Byte Counter Units field to 0x01 (KiB (kibibytes)).
•将“字节计数器单位”字段设置为0x01（KiB（千字节））。
• Set the Max Total Number of VIDs field to 2 or greater.
•将“ VID的最大总数”字段设置为2或更大。
• If the Multi-AP Agent onboards to a Multi-AP Controller that implements Profile-1, the Multi-AP Agent shall set the Byte Counter Units field to 0x00 (bytes) and report the values of the BytesSent and BytesRecevied fields in the Associated STA Traffic Stats TLV in bytes.
•如果Multi-AP Agent随附于实现Profile-1的Multi-AP Controller，则Multi-AP Agent必须将“字节计数器单位”字段设置为0x00（字节），并报告以字节为单位的关联STA Traffic Stats TLV中BytesSent和BytesRecevied字段的值。
The AP Capability Report message shall contain the same MID that was received in the AP Capability Query message.
AP能力报告消息应包含与AP能力查询消息中收到的MID相同的MID。
9.2 Client capability（客户端能力）
Multi-AP Client Capability Query and Client Capability Report messages enable a Multi-AP Controller to obtain capability information of a client STA associated with a Multi-AP Agent.
