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
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth1.109       | 109  | eth1
eth1.104       | 104  | eth1
eth1.112       | 112  | eth1
eth1.113       | 113  | eth1
eth1.124       | 124  | eth1
