DHCP服务器
第一种 windows服务器操作系统
在windows服务器操作系统上配置好DHCP作用域，客户主机只要将TCP/IP属性设置为自动获取，就可以从服务器取得IP地址。
第二种：将路由器作为DHCP服务器
在AR_DHCP_Server上做好配置，配置如下：
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]
[Huawei]sysname AR_DHCP_Server
[AR_DHCP_Server]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[AR_DHCP_Server]ip pool pool_1
Info: It's successful to create an IP address pool.
[AR_DHCP_Server-ip-pool-pool_1]network 192.168.1.0 mask 255.255.255.0
[AR_DHCP_Server-ip-pool-pool_1]gateway-list 192.168.1.254
[AR_DHCP_Server-ip-pool-pool_1]dns-list 202.96.128.86
[AR_DHCP_Server-ip-pool-pool_1]excluded-ip-address 192.168.1.200 192.168.1.253
[AR_DHCP_Server-ip-pool-pool_1]quit
[AR_DHCP_Server]
[AR_DHCP_Server]
[AR_DHCP_Server]int g0/0/1
[AR_DHCP_Server-GigabitEthernet0/0/1]ip address 192.168.1.254 255.255.255.0
Jun 5 2019 00:05:18-08:00 AR_DHCP_Server %%01IFNET/4/LINK_STATE(l)[0]:The line
protocol IP on the interface GigabitEthernet0/0/1 has entered the UP state.
[AR_DHCP_Server-GigabitEthernet0/0/1]dhcp select global
[AR_DHCP_Server-GigabitEthernet0/0/1]quit
[AR_DHCP_Server]
交换机上不需要做配置;
通过GE0/0/1端口用wireshark捕获到的数据包如：
在PC上查看，可见客户机已获取到IP地址
第三种：将路由器作为DHCP服务器，为多个VLAN的主机分配IP地址；
配置AR_DHCP_Server路由器，建立2个地址池；
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
