使⽤IP和vconfig配置vlan⼦接⼝

⼀、使⽤IP命令配置

此前ArchLinux⽤vconfig命令设置VLANs，该命令已被ip命令取代。下⾯的范例假定⽹⼝⽹⼝是enp125s0f0，名名

字是enp125s0f0.100，vlanidvlanid是100。

1.创建VLAN设备

⽤下列命令添加VLAN⽹⼝：

#iplinkaddlinkenp125s0f0nameenp125s0f0.100typevlanid100

执⾏iplink命令确认VLAN已创建。

这个VLAN⽹⼝就像⼀个普通的物理⽹⼝，所有流经这个⽹⼝的数据包将被加上VLANtag并流经它关联的物理⽹⼝（本例中

的enp125s0f0）。仅配置为相同VLAN的设备可接收这些数据包，否则将被丢弃。

2.添加IP

#iplinktdevenp125s0f0.100up

3.关闭设备

4.移除设备

#iplinkdeleteenp125s0f0.100

⼆、使⽤vconfig配置

1.安装vlan(vconfig)和加载8021q模块

#aptitudeinstallvlan

#modprobe8021q

或：

#yuminstallvconfig

#modprobe8021q

#lsmod|grep-i8021q

2.使⽤linuxvconfig命令配置vlan

#vconfigaddenp8s0f1100

#vconfigaddenp8s0f1200

在enp8s0f1接⼝上配置两个VLAN

#vco薄荷糖的功效与作用 nfigt_flagenp8s0f1腐竹凉菜 .10011

#vconfigt_flagenp8s0f1.20011

设置VLAN的REORDER_HDR参数，默认就⾏了。

可以使⽤cat/proc/net/vlan/enp8s0f1.100查看enp8s0f1.100参数

配置⽹络信息

#ifco朱槿牡丹 nfigenp8s0f10.0.0.0

#ifconfigenp8s0f1.100192.168.100.50netmask255.255.255.0up

#ifconfigenp8s0f1.200192.168.200.50netmask255.255.255.0up

删除VLAN命令

#vconfigremenp8s0f1.100

#vconfigremenp8s0f1.200

3.将VLAN信息写⼊配置⽂件

#echo"modprobe8021q">>/etc/

开机加载8021q模块，或者使⽤

echo"8021q">>/etc/modules

#cp/etc/network/interfaces/etc/network/t

#vim/etc/network/interfaces
