華為路由器上的 DHCP 配置步驟：
1、確保客戶端與服務器之間的鏈路是互通的；
#SW1
創建 VLAN 10
將端口放入VLAN 10 ；
#Gateway
在 Router 上為 VLAN 10 配置一個 網關IP 地址；
2、配置 DHCP 客戶端；
# 進入 PC ，選擇“自動獲取”，點“應用”；
3、配置 DHCP 服務器；
# 創建 IP 地址池；
ip pool VLAN-10
network 192.168.10.0 mask 255.255.255.0
gateway-list 192.168.10.254
dns-list 8.8.8.8
lease day 3
# 開啟 DHCP 服務 ；
dhcp enable
# 在 接收 DHCP 報文的端口上，配置 DHCP 的選擇方式 - global ；
interface gi0/0/0
dhcp select global // 表示的是當端口上收到 DHCP 報文以后
直接去 DHCP 服務器在全局配置的IP
地址池中選擇一個可用的IP地址；
