1.2 Clear ARP Table

[root@pc ~]# ip neigh flush all

1.3 Vlanインターフェース作成
インターフェース名「vlan100」、設定ファイル名「ifcfg-vlan100」、「VlanID:100」、
物理インターフェース「eth0」所属のVlanインターフェースを作成する。

[root@pc ~]#ip link add link eth0 name vlan100 type vlan id 100

ifcfg-vlan100を以下の内容で作成する。

[root@pc ~]#vim /etc/sysconfig/network-scripts/ifcfg-vlan100
[[VLAN]]=yes
PHYSDEV="eth0"
DEVICE="vlan100"
NM_CONTROLLED="no"
BOOTPROTO="static"
ONBOOT=yes
IPADDR=192.168.100.1
PREFIX=24
