Atheros AP Driver Command Line Interface Study

Wireless Tools

In the Atheros driver, two device types are created when the AP is brought up.

• radio layer[ATH/HAL layer]--实例化--> wifi N device.
• protocol[802.11] layer--实例化--> ath N device.

Two main programs of the wireless tools suite:

• iwconfig
• iwpriv

Many commands are only effective before the AP interface is in the up state, so these commands must be performed prior to issuing the ifconfig up command to the interface.

• radio层不支持iwconfig命令，该命令只能用在协议层。
• 任何用在AP上的ifconfig命令只能应用于协议层设备。

iwconfig commands

iwconfig命令是一套固定的用于设定和操作WLAN接口的命令集。

参数：

parameter	format	description
ap	iwconfig ath N ap MAC
channel	iwconfig ath N channel args
enc key	iwconfig ath N key [idx] key_val
essid	iwconfig ath N essid "name"
frag	iwconfig ath N frag level
freq	iwconfig ath N freq frequency
rate	iwconfig ath N rate rateval/auto
rts	iwconfig ath N rts pkt_size
txpower	iwconfig ath N txpower power_num

iwpriv commands

iwpriv命令可用于各层。有些命令在各层间复用。建议复用的命令出现的时候，使用radio层命令。

聚合命令

• AMPDU/getAMPDU 帧聚合参数
• AMPDUFrames/getAMPDUFrames AMPDU聚合帧的最大子帧数
• AMPDULim/getAMPDULim 限制AMPDU聚合帧的字节数

eg:
iwpriv wifiN AMPDU 1

Association/ACL命令

• addmac/delmac/getmac/maccmd/get_maccmd 这些命令设定或修改MAC过滤列表。
  addmac:增加指定MAC地址到访问控制列表中（ACL）。
  delmac:
  getmac:
  maccmd:指示ACL如何限制访问AP

• ap_bridge/get_ap_bridge
  使能或禁止AP驱动的桥接功能。

• kickmac:forces the AP to disassociate the specified STA.
