CLI Configuration
To configure the device as a DHCP server for a subnet:

• 定义dhcp网段并设置范围 (for example, 192.168.1.33).user@host# set system services dhcp pool 192.168.1.0/24 address-range low 192.168.1.33
  
• 定义dhcp网段并设置最高范围 (for example, 192.168.1.64).user@host# set system services dhcp pool 192.168.1.0/24 address-range high 192.168.1.64
  
• 定义dhcp域名(for example, example.net).user@host# set system services dhcp pool 192.168.1.0/24 domain-name example.net
  
• 定义dhcp地址池的 DNS (for example, 192.168.1.1).user@host# set system services dhcp pool 192.168.1.0/24 name-server 192.168.1.1
  
• 定义dhcp地址池的网关地址(for example, 192.168.1.1).user@host# set system services dhcp pool 192.168.1.0/24 router 192.168.1.1
  
• 定义dhcp地址池的租约时间 (for example, 3600).user@host# set system services dhcp pool 192.168.1.0/24 default-lease-time 3600
  
• 定义dhcp服务在那个接口允许（例：在UNtrust的fe-0/0/0.5放行）
  

　　user@host# set security zones security-zone untrust interfaces fe-0/0/5.0 host-inbound-traffic system-services dhcp
user@host# set security zones security-zone untrust interfaces fe-0/0/6.0 host-inbound-traffic system-services dhcp
　　注意哦：接口网段要和地址池一样哦！

user@host# set interfaces fe-0/0/6 unit 0 family inet address 192.168.1.1/24
