H3C华三交换机DHCP服务开局配置

####开启dhcp服务#####
<Sysname>system-view
[Sysname]dhcp enable
####配置dhcp地址池名称ap，这里ap是名称####
[Sysname]dhcp server ip-pool ap
####配置dhcp地址池网段####
[Sysname-dhcp-pool-ap]network 192.168.20.0 mask 255.255.255.0
####配置dhcp地址池网关地址####
[Sysname-dhcp-pool-ap]gateway-list 192.168.20.254
####配置dhcp地址池dns服务器####
[Sysname-dhcp-pool-ap]dns-list 114.114.114.114 223.5.5.5
####排除IP####
[Sysname]dhcp server forbidden-ip 192.168.20.250

####建立VLAN，配置备注描述，相当于备注这个VLAN是干什么使用的，便于维护####
[Sysname]vlan 20
[Sysname-vlan20]description ap
[Sysname-vlan20]quit

####配置VLAN20 VLAN接口地址，也就是对应的DHCP地址池网关####
[Sysname]interface Vlan-interface 20
[Sysname-Vlan-interface20]ip address 192.168.20.254 24
[Sysname-Vlan-interface20]quit
####将交换机G1/0/1口划入VLAN20####
[Sysname]interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1]port link-type access
[Sysname-GigabitEthernet1/0/1]port access vlan 20
[Sysname-GigabitEthernet1/0/1]quit
####电脑客户端接入交换机G1/0/1口即可获取到IP####
[Sysname]display dhcp server ip-in-use
