1.实验拓扑图：
2.三层交换配置：
[Quidway]vlan 10
[Quidway-vlan10]port e0/1
[Quidway-vlan10]vlan 100
[Quidway-vlan100]port e0/24
[Quidway-vlan100]int vlan 10
[Quidway-Vlan-interface10]ip add 192.168.10.254 ?
X.X.X.X IP mask
[Quidway-Vlan-interface10]ip add 192.168.10.254 255.255.255.0
[Quidway-Vlan-interface10]int vlan 100
[Quidway-Vlan-interface100]ip add 192.168.100.254 255.255.255.0
<Quidway>sys
进入系统视图, 键入Ctrl+Z退回到用户视图.
[Quidway]dhcp-server ?
INTEGER<0-19> DHCP 服务器的组号
detect 检测伪DHCP服务器
[Quidway]dhcp-server 1 ?
ip 指定IP地址
[Quidway]dhcp-server 1 ip ?
X.X.X.X DHCP 服务器组的第一个IP地址
[Quidway]dhcp-server 1 ip 192.168.100.100 ?
X.X.X.X DHCP 服务器组的第二个IP地址 //可设备份dhcp服务器
<cr>
[Quidway]dhcp-server 1 ip 192.168.100.100
[Quidway]int vlan 10
[Quidway-Vlan-interface10]d?
description dhcp-server display
[Quidway-Vlan-interface10]dhcp-server ?
INTEGER<0-19> DHCP 服务器的组号
[Quidway-Vlan-interface10]dhcp-server 1
3.DHCP服务器配置：
用防火墙作为dhcp服务器：
<H3C>display version

进入系统视图, 键入Ctrl+Z退回到用户视图.
[H3C]dhcp enable
DHCP任务已经启动!
[H3C]dhcp ?
enable DHCP服务开启
relay DHCP中继
select 设置接口的DHCP报文处理模式
server DHCP服务器
[H3C]dhcp server ?
accounting 发送开始/停止计费信息
bims-server BIMS 服务器
detect 当地DHCP服务器自动检测
dns-list DNS 服务器
domain-name 域名
expired 动态用户的地址租约时间
forbidden-ip 被保留的地址范围
ip-pool 地址池
nbns-list NetBIOS(WINS)名字服务器
netbios-type NetBIOS节点类型
option 原DHCP options
ping 指定运行DHCP时PING的参数
relay DHCP中继
voice-config 184选项
[H3C]dhcp server ip-pool ?
STRING<1-35> 全局地址池名称
[H3C]dhcp server ip-pool gjp
[H3C-dhcp-pool-gjp]network 192.168.10.0 //分配的地址范围
[H3C-dhcp-pool-gjp]gateway-list 192.168.10.254 //分配的网关
[H3C-dhcp-pool-gjp]dns-list 222.85.85.85 //分配的DNS
[H3C-dhcp-pool-gjp]quit
[H3C]ip route-static 0.0.0.0 0 192.168.100.254 //默认网关
[H3C]ping 192.168.100.254
PING 192.168.100.254: 56 字节，按CTRL_C 中断.
答复从 192.168.100.254: 字节数=56 顺序号=1 生存时间=255 时间 = 13 毫秒
答复从 192.168.100.254: 字节数=56 顺序号=2 生存时间=255 时间 = 5 毫秒
答复从 192.168.100.254: 字节数=56 顺序号=3 生存时间=255 时间 = 7 毫秒
4. 客户机动态获取ip
用一台pc 自动获取ip，在dos下，执行：ipconfig /release 释放已获得的ip，用ipconfig /renew 重新获取新的ip !
5.查看客户机获取IP的情况：
[H3C]display dhcp server ?
conflict DHCP 地址冲突
expired DHCP 超期地址
free-ip 空闲地址
ip-in-use DHCP 地址绑定
statistics DHCP服务器统计信息
tree 打印地址池树结构
[H3C]display dhcp server ip-in-use ?
all 所有信息
interface 接口
ip 特定IP
pool 地址池
[H3C]display dhcp server ip-in-use all
Global pool:
IP address Client-identifier/ Lease expiration Type
Hardware address
192.168.10.1 0026-9e81-2692 Sep 9 2012 10:51:32 AM Auto:COMMITTED
Interface pool:
IP address Client-identifier/ Lease expiration Type
Hardware address
