在command 命令运行ifconfig之后，出现很多名词

lo0
gif0
stf0
en0
fw0
en1
vmnet1

查查看

lo0 = loopback
gif0 = Software Network Interface
stf0 = 6to4 tunnel interface
en0 = Ethernet 0
fw0 = Firewire
en1 = Ethernet 1
vmnet1 = Virtual Interface

那en0 en1 en2 en3 en4 怎么这么多？？？
运行一下命令：

networksetup -listallhardwareports

Hardware Port: Wi-Fi
Device: en0
Ethernet Address: c4:b3:01:bd:ad:1d

Hardware Port: Bluetooth PAN
Device: en3
Ethernet Address: c4:b3:01:bd:ad:1e

Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: 4a:00:07:4d:b2:b0

Hardware Port: Thunderbolt 2
Device: en2
Ethernet Address: 4a:00:07:4d:b2:b1

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: 4a:00:07:4d:b2:b0

 

原来是Wi-Fi，蓝牙，thunderbolt…
