DHCP中继

1、对Cloud进行如下设置，选择VMnet1网卡
2、二层交换机的命令：

vlan batch 10 20 30 100

interface Ethernet0/0/1

port link-type access

port default vlan 100

interface Ethernet0/0/2

port link-type access

port default vlan 10

interface Ethernet0/0/3

port link-type access

port default vlan 20

interface Ethernet0/0/4

port link-type trunk

port trunk allow-pass vlan 2 to 4094

3、三层交换机命令：

vlan batch 10 20 100

interface Vlanif10

ip address 192.168.10.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 192.168.100.100

interface Vlanif20

ip address 192.168.20.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 192.168.100.100

interface Vlanif100

ip address 192.168.100.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 192.168.100.100

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 2 to 4094

4、将虚拟机选择VMnet1网卡连接：
5、为DHCP服务器进行如下IP配置：
6、重启一下网卡：
7、修改配置文件，添加vlan10，vlan20，vlan30网段的IP地址池：
8、启动DHCP服务：
9、验证，将PC配置改为DHCP
10、输入ipcongig /renew获取IP地址：
