是否有Mac OS X相当于Linux iwconfig命令？

我正在寻找Mac OS X中的命令行工具，它可以执行相同的操作 iwconfig的 Linux中的命令。

例：

kirkland@x220:~/src/byobu/byobu$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"serenity"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:11:22:33:44:55   
          Bit Rate=1 Mb/s   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-17 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:70   Missed beacon:0

ifconfig 提供有关所有接口的信息，包括WLAN。通常是WLAN接口 en1。

$ ifconfig en1
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        ether 20:c9:d0:97:22:e9

airport -I 提供有关WLAN接口的信息（有关其他选项，请查看手册页）
