项目拓扑图:


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:
