iw输出意义？

Question

我找不到关于这个输出的任何文档：

# iw dev

phy#0
         Interface wlan0
                 ifindex 3
                 wdev 0x1
                 addr xx:xx:xx:xx:xx:xx
                 type managed

有人能参考wdev线的含义吗？

提前感谢，干杯！

我认为'wdev‘只是无线接口的另一个标识符。

例如，这个to命令应该打印出相同的内容(在您的例子中)

iw dev wlan0 link
iw wdev 0x1 link

在我的电脑里我得到了这个输出

# iw dev
phy#1
    Interface wlan1
            ifindex 7
            wdev 0x100000002
            addr 14:cc:20:61:36:9b
            type managed
            channel 11 (2462 MHz), width: 20 MHz (no HT), center1: 2462 MHz
phy#0
    Interface wlan0
            ifindex 4
            wdev 0x1
            addr 14:cc:20:5a:47:90
            type managed

希望这对你有用。
