添加vlan

[root@localhost network-scripts]# vconfig add eth1 109

配置文件,此处配置了vlan109使用子接口进行多ip配置:

[root@localhost network-scripts]# cat ifcfg-eth1.109\:0

DEVICE=eth1.109:0

HWADDR=68:05:CA:25:FC:43

TYPE=Ethernet

UUID=05ed80f3-7699-4702-b93e-016d8b84067d

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=none

VLAN=yes

IPADDR=192.168.15.230

NETMASK=255.255.255.0

[root@localhost network-scripts]# cat ifcfg-eth1.109\:1

DEVICE=eth1.109:1

HWADDR=68:05:CA:25:FC:43

TYPE=Ethernet

UUID=05ed80f3-7699-4702-b93e-016d8b84067d

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=none

IPADDR=192.168.50.230

NETMASK=255.255.255.0

VLAN=yes

如果是一个vlan一个ip地址如下:

[root@localhost network-scripts]# cat ifcfg-eth1.112

DEVICE=eth1.112

HWADDR=68:05:CA:25:FC:43

TYPE=Ethernet

UUID=05ed80f3-7699-4702-b93e-016d8b84067d

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=none

VLAN=yes

IPADDR=192.168.46.230

NETMASK=255.255.255.0

以上配置重启网卡生效,自动创建vlan关系:

[root@localhost network-scripts]# service network restart

Shutting down interface eth1.104:                          [  OK  ]

Shutting down interface eth1.112:                          [  OK  ]

Shutting down interface eth1.113:                          [  OK  ]

Shutting down interface eth1.124:                          [  OK  ]

查看vlan信息:

[root@localhost network-scripts]# cat /proc/net/vlan/config

VLAN Dev name	 | VLAN ID

eth1.112       | 112  | eth1
