命令说明
新交换机，开局配置DHCP服务，给局域网电脑客户端分配IP地址，并保留几个IP地址以供固定IP地址的设备使用。
配置案例
配置DHCP
####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
应用配置
####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
IP address Client identifier/ Lease expiration Type
