ubuntu 网卡名称重命名
<h1>ubuntu 网卡名称重命名</h1><p> </p>
<p>参考：https://blog.csdn.net/hzj_001/article/details/81587824</p>
<div class="cnblogs_code">
<pre>biosdevname 和 net.ifnames 两种命名规范
---------------------------------------
net.ifnames 的命名规范为: 设备类型+设备位置+数字
设备类型：
en 表示Ethernet
wl 表示WLAN
ww 表示无线广域网WWAN
实际的例子:
eno1 板载网卡
enp0s2 pci网卡
ens33 pci网卡
wlp3s0 PCI无线网卡
wwp0s29f7u2i2 4G modem
wlp0s2f1u4u1 连接在USB Hub上的无线网卡
enx78e7d1ea46da pci网卡
---------------------------------------
biosdevname 的命名规范为：
实际的例子:
em1 板载网卡
p3p4 pci网卡
p3p4_1 虚拟网卡
