我有一台 MacBook Pro 15" 2018(Touch Bar)。我看到它有很多网络接口。我想知道它们是什么/它们做什么。我做了一些研究,但我无法真正弄清楚所有他们,这是SCNetworkInterfaceInfo.UserDefinedName
我从中找到的信息这个答案:
- ap1:?
- awdl0:?
- llw0:?
- utun0:?
- utun1:?
- lo0:环回(本地主机)
- gif0:软件网络接口
- stf0:6to4隧道接口
- en0:物理无线
- en1: 雷电 1
- en2: 雷电 2
- en3:雷电3
- en4:雷电4
- en5:iBridge / Apple T2 控制器
- en6:蓝牙 PAN
- en8:iPhone USB
- en9:虚拟机网络接口
- en10: iPad
- bridge0:雷电桥
