Ubuntu 配置 Vlan 和 基于Vlan 的 DHCP server

安装vconfig命令，apt-get install vlan

service NetworkManager restart （如果没有网络报错，不必执行此命令）

vconfig add eth1 35 // eth1为物理网络接口名称，35为 802.1q tag id 也即 vlan ID

ifconfig eth1.35 192.168.128.1 // 对上步增加的子接口eth1.35 添加IP地址

ifconfig // 察看此子接口是否成功配置

==================================================

DHCP Server:

1. sudo apt-get install isc-dhcp-server

2. vi /etc/default/isc-dhcp-server

   INTERFACES="eth1.35"

3.vi /etc/dhcp/dhcpd.conf 加入

subnet 192.168.128.0 netmask 255.255.255.0 {
    range 192.168.128.30 192.168.128.40;
    option broadcast-address 192.168.128.255;
    option routers 192.168.128.1;
    default-lease-time 6000;
    max-lease-time 8000000;
}

sudo /etc/init.d/isc-dhcp-server start
/usr/sbin/dhcpd
service dhcpd start
service isc-dhcp-server restart
/etc/rc.d/init.d/dhcpd start

ps -aux | grep dhcpd // 察看dhcpd进程是否成功开启
