华为5700交换机DHCP基础配置案例

配置两个地址池：192.168.1.0/24和192.168.2.0/24

配置两个VLAN：10和20

将四台主机分别加入VLAN

自动获取IP地址，确保全网互通。

步骤：

一、DHCP交换机上

在DHCP交换机上创建VLAN10，20；IP地址池VLAN 10和IP地址池VLAN 20 [DHCP]DHCP enable //打开DHCP功能

[DHCP]vlan batch 10 20 //创建两个Vlan 10和20

[DHCP]ip pool vlan10 //新增地址池名称为Vlan10

[DHCP]gateway-list 192.168.1.254 //设置网关

[DHCP]network 192.168.1.0 mask 255.255.255.0 //设置地址段

[DHCP]excluded-ip-address 192.168.1.200 192.168.1.253 //可以设置排除IP范围[DHCP]lease day 5 //设置获取到IP地址的有效期为5天

[DHCP]dns-list 114.114.114.114 //设置客户机DNS，多条命令可设置多个

[DHCP]ip pool VLAN 20 //新增地址池名称为Vlan20

[DHCP]gateway-list 192.168.2.254 //设置网关

[DHCP]network 192.168.2.0 mask 255.255.255.0 //设置地址池

[DHCP]excluded-ip-address 192.168.2.100 192.168.1.200 //可以设置排除IP范围[DHCP]lease day 5 //设置获取到IP地址的有效期为5天

[DHCP]dns-list 8.8.8.8 //设置客户机DNS，多条命令可设置多个

分配vlanif 端口配置

[DHCP]interface vlanif10 //进入vlanif10接口

[DHCP]ip address 192.168.1.254 255.255.255.0 //配置接口IP

[DHCP]dhcp select global

[DHCP] interface vlanif20 //进入vlanif10接口

[DHCP]ip address 192.168.2.254 255.255.255.0 //配置接口IP [DHCP]dhcp select global

给DHCP服务器1口和2口配置trunk链路

[DHCP]interface g0/0/1

[DHCP]port link-type trunk

[DHCP]port trunk allow-pass Vlan 10

[DHCP]interface g0/0/2

[DHCP]port link-type trunk

[DHCP]port trunk allow-pass Vlan 20

二、SW1交换机上

[SW1]DHCP enable //打开DHCP功能

在交换机一上把端口1；2加入VLAN 10；端口3设置成trunk链路[SW1]vlan batch 10 //创建两个Vlan 10

[SW1]interface g0/0/1 //进入接口1

[SW1]port link-type access //配置接口类型为access

[SW1]port default vlan 10 //接口配置属于Vlan10

[SW1]interface g0/0/2 //进入接口2

[SW1]port link-type access //配置接口类型access

[SW1]port default vlan 10 //接口配置属于Vlan10

[SW1]interface g0/0/3 //进入接口3

[SW1]port link-type trunk //配置接口类型trunk

[SW1]port trunk allow-pass vlan 10 //配置哪些Vlan充许通过

三、SW2交换机上也做相同操作
