vconfig命令

vconfig命令是VLAN配置命令。

实例

1,安装vlan（vconfig）和加载8021q模块

[root@test0001~]#yum install vconfig [root@test0001~]#modprobe 8021q [root@test0001~]#lsmod |grep -i 8021q

2,在eth0接口上配置两个VLAN

[root@test0001~]#vconfig add eth0 100 Added VLAN with VID == 100 to IF -:eth0:- [root@test0001~]#vconfig add eth0 200 Added VLAN with VID == 200 to IF -:eth0:-

3,设置VLAN的REORDER_HDR参数，默认就行了

[root@test0001~]#vconfig set_flag eth0.100 1 1 Set flag on device -:eth0.100:- Should be visible in /proc/net/vlan/eth0.100 [root@test0001~]#vconfig set_flag eth0.200 1 1 Set flag on device -:eth0.200:- Should be visible in /proc/net/vlan/eth0.200

4,配置网络信息

[root@test0001~]#ifconfig eth0 0.0.0.0 [root@test0001~]#ifconfig eth0.100 172.16.1.8 netmask 255.255.255.0 up [root@test0001~]#ifconfig eth0.200 172.16.2.8 netmask 255.255.255.0 up

5,删除VLAN命令

[root@test0001~]#vconfig rem eth0.100 Removed VLAN -:eth0.100:- [root@test0001~]#vconfig rem eth0.200 Removed VLAN -:eth0.200:-
