【网络】配置设备作为DHCP 服务器示例（基于接口地址池）

网络结构如下：

组网要求：

操作步骤：

我们无需在傻瓜交换机上配置任何东西，傻瓜交换机仅仅起到接入网络的作用
所有配置均在汇聚交换机1上完成

汇聚交换机1上的配置
1.配置设备名称并开启DHCP功能和创建vlan

<Huawei>system-view                       #进入系统视图
[Huawei]sysname  DHCP-server              #配置系统名称为DHCP-server
[DHCP-server]vlan 10                      #创建VLAN 10
[DHCP-server-vlan10]quit                  #退出VLAN 10
[DHCP-server]vlan 20                      #创建VLAN 20
[DHCP-server-vlan20]quit                  #退出vlan 20

2.配置接口加入vlan
#配置接口G0/0/1加入VLAN10

[DHCP-server]interface  GigabitEthernet  0/0/1                 #进入千兆以太网端口 0/0/1
[DHCP-server-GigabitEthernet0/0/1]port link-type access        #配置端口的链路类型为ACCESS
[DHCP-server-GigabitEthernet0/0/1]port default  vlan  10       #配置端口的默认VLAN 为10
[DHCP-server-GigabitEthernet0/0/1]quit                         #退出千兆以太网端口 0/0/1
[DHCP-server]

#配置接口G0/0/2加入VLAN20

[DHCP-server]interface  GigabitEthernet  0/0/2                 #进入千兆以太网端口 0/0/2
[DHCP-server-GigabitEthernet0/0/2]port link-type access        #配置端口的链路类型为ACCESS
[DHCP-server-GigabitEthernet0/0/2]port default  vlan  20       #配置端口的默认VLAN 为10
[DHCP-server-GigabitEthernet0/0/2]quit                         #退出千兆以太网端口 0/0/2
[DHCP-server]

[DHCP-server]interface  Vlanif 10                     #进入VLANIF 10 接口
[DHCP-server-Vlanif10]ip address  10.10.10.1 24       #配置IP地址为10.10.10.1，子网掩码长度为24位
[DHCP-server-Vlanif10]quit                            #退出VLANIF 10 接口
[DHCP-server]

[DHCP-server]interface  Vlanif 20                     #进入VLANIF 20 接口
[DHCP-server-Vlanif20]ip address  10.10.20.1 24       #配置IP地址为10.10.20.1，子网掩码长度为24位
[DHCP-server-Vlanif20]quit                            #退出VLANIF 20 接口
[DHCP-server]

[DHCP-server]interface  Vlanif  10                                         #进入VLANIF 10 端口
[DHCP-server-Vlanif10]dhcp select  interface                               #配置VLANIF10使用接口地址池
[DHCP-server-Vlanif10]dhcp server  lease  day  1                           #配置DHCP服务租期位1天
[DHCP-server-Vlanif10]dhcp server  dns-list 223.5.5.5 223.6.6.6            #配置DHCP服务dns列表位 223.5.5.5 223.6.6.6
[DHCP-server-Vlanif10]dhcp server  domain-name maoxianshengdezaocha.com    #配置DHCP服务分配的域名为 maoxianshengdezaocha.com
[DHCP-server-Vlanif10]quit                                                 #退出VLANIF 10 端口
[DHCP-server]

[DHCP-server]interface  Vlanif  20                                         #进入VLANIF 20 端口
[DHCP-server-Vlanif20]dhcp select  interface                               #配置VLANIF 20使用接口地址池
[DHCP-server-Vlanif20]dhcp server  lease  day  1                           #配置DHCP服务租期位1天
[DHCP-server-Vlanif20]dhcp server  dns-list 223.5.5.5 223.6.6.6            #配置DHCP服务dns列表位 223.5.5.5 223.6.6.6
[DHCP-server-Vlanif20]dhcp server  domain-name maoxianshengdezaocha.com    #配置DHCP服务分配的域名为 maoxianshengdezaocha.com
[DHCP-server-Vlanif20]quit                                                 #退出VLANIF 20 端口
[DHCP-server]
