1.6. 使用 udev 规则分配用户定义的网络接口名称

流程

1. 显示所有网络接口及其 MAC 地址：

   # ip link list
   
   enp6s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
       link/ether b4:96:91:14:ae:58 brd ff:ff:ff:ff:ff:ff
   enp6s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
       link/ether b4:96:91:14:ae:5a brd ff:ff:ff:ff:ff:ff
   enp4s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
       link/ether 00:90:fa:6a:7d:90 brd ff:ff:ff:ff:ff:ff

2. 创建具有以下内容的文件 /etc/udev/rules.d/70-custom-ifnames.rules ：

   SUBSYSTEM=="net",ACTION=="add",ATTR{address}=="b4:96:91:14:ae:58",ATTR{type}=="1",NAME="provider0"
   SUBSYSTEM=="net",ACTION=="add",ATTR{address}=="b4:96:91:14:ae:5a",ATTR{type}=="1",NAME="provider1"
   SUBSYSTEM=="net",ACTION=="add",ATTR{address}=="00:90:fa:6a:7d:90",ATTR{type}=="1",NAME="dmz"

   这些规则与网络接口的 MAC 地址相匹配，并将它们重命名为 NAME 属性中指定的名称。在这些示例中，ATTR{type} 参数值 1 定义了接口类型为 Ethernet。

验证

1. 重启系统：

   # reboot

2. 验证每个 MAC 地址的接口名称是否与您在规则文件的 NAME 参数中设置的值相匹配：

   # ip link show
   
   provider0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
       link/ether b4:96:91:14:ae:58 brd ff:ff:ff:ff:ff:ff
      altname enp6s0f0
   provider1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
       link/ether b4:96:91:14:ae:5a brd ff:ff:ff:ff:ff:ff
       altname enp6s0f1
   dmz: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
       link/ether 00:90:fa:6a:7d:90 brd ff:ff:ff:ff:ff:ff
       altname enp4s0f0
