注：本实验的路由器使用的是AR2240，交换机是S3700，以及4台PC机。
拓扑图如下:
拓扑中左边用于练习全局DHCP配置,右边用于接口DHCP配置.
一.进入g0/0/1,添加接口IP
命令:
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys R1
[R1]int g0/0/1
[R1-GigabitEthernet0/0/1]ip add 192.168.10.254 24
Apr 7 2020 16:38:59-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
[R1-GigabitEthernet0/0/1]
二.配置DHCP
命令:
[R1]dhcp enable ##启用DHCP功能
Info: The operation may take a few seconds. Please wait for a moment.done.
[R1]ip pool pool1 ##创建一个pool1地址池
Info: It's successful to create an IP address pool.
[R1-ip-pool-pool1]
[R1-ip-pool-pool1]netw
[R1-ip-pool-pool1]network 192.168.10.0 m
[R1-ip-pool-pool1]network 192.168.10.0 mask 24 ##宣告网段
[R1-ip-pool-pool1]ga
[R1-ip-pool-pool1]gateway-list 192.168.10.254 ##添加网关
[R1-ip-pool-pool1]dn
[R1-ip-pool-pool1]dns-list 8.8.8.8 ##添加DNS
三.进入接口启用全局模式
命令:
[R1]int g0/0/1 ##进入相应的接口
[R1-GigabitEthernet0/0/1]dh
[R1-GigabitEthernet0/0/1]dhcp se
[R1-GigabitEthernet0/0/1]dhcp select g
[R1-GigabitEthernet0/0/1]dhcp select global ##启用全局模式
四.进入PC验证是否配置成功
1.进入PC机点击DHCP
2.命令行中输入:ipconfig
看到显示上述信息则证明DHCP全局配置成功.
接口配置DHCP(在拓扑的右边实验)
一.接口dhcp配置
命令:
[R1]
[R1]int g0/0/2 ##进入相应的接口
[R1-GigabitEthernet0/0/2]ip add
[R1-GigabitEthernet0/0/2]ip address 172.16.10.254 255.255.255.0 ##配置IP地址范围
Apr 7 2020 16:57:12-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface GigabitEthernet0/0/2 has entered the UP state.
[R1-GigabitEthernet0/0/2]dh
[R1-GigabitEthernet0/0/2]dhcp se
[R1-GigabitEthernet0/0/2]dhcp select int
[R1-GigabitEthernet0/0/2]dhcp select interface ##选择接口模式
[R1-GigabitEthernet0/0/2]dh
[R1-GigabitEthernet0/0/2]dhcp ser
[R1-GigabitEthernet0/0/2]dhcp server dn
[R1-GigabitEthernet0/0/2]dhcp server dns-list 114.114.114.114 ##添加DNS
二.进入PC验证
看到上述命令输出则表明接口DHCP配置成功.
全局模式可选操作:
9、excluded－IP－address １９２.１６８.１.２５０ ＃＃排除地址的操作
10、excluded－IP－address １９２.１６８.１.１ １９２.１６８.１.１０ ##代表排除１到１０ip
11、lease day 0 hour 1 minute 0 ##调整租期
12、static-bind IP-address 192.168.1.88 mac-address XXXX-XXXX-XXXX ##为pc绑定某个IP
接口模式可选操作:
6、DHCP server excluded－IP－address １９２.１６８.１.２５０ ＃＃排除地址的操作
7、DHCP server excluded－IP－address １９２.１６８.１.１ １９２.１６８.１.１０ ##排除1-10IP地址
8、DHCP server lease day 0 hour 1 minute 0 ##调整租期
9、DHCP server static－bind IP－address １９２.１６８.１.８８ ｍａｃ－address XXXX－X
PC上的操作:
在PC命令行上操作：
ｉｐｃｏｎｆｉｇ ＃＃显示IP地址等信息
ｉｐｃｏｎｆｉｇ ／renew ＃＃重新获取IP地址
ｉｐｃｏｎｆｉｇ ／release ＃＃释放地址
ｉｐｃｏｎｆｉｇ ／？
