H3C 配置DHCP服务器

 

一.分配相同网络的ip地址

 

实验目的：通过wang1对pc机和wang2分配不同网段的ip地址！

 

 

配置wang1为DHCP服务器

[H3C]sys wang1

[wang1]dhcp enable                  //开启DHCP服务功能

 DHCP is enabled successfully!

 

[wang1]dhcp server ip-pool ?          //创建地址池，最多能创建35个地址池！

  STRING<1-35>  Pool name

[wang1]dhcp server ip-pool wnt        //创建地址池

[wang1-dhcp-pool-wnt]network 192.168.1.1   

  INTEGER<1-30>  Subnet mask length

  mask           Specify a subnet mask

  <cr>

 

[wang1-dhcp-pool-wnt]network 192.168.1.0 24    //分配的ip地址网络

[wang1-dhcp-pool-wnt]gateway-list 192.168.1.254  //网关

[wang1-dhcp-pool-wnt]dns-list 202.102.152.3      //DNS服务器

[wang1-dhcp-pool-wnt]expired ?                //租约时间

  day        Expired days ----------------------》设置租约时间

  unlimited  Unlimited lease--------------------->设置租约时间为永久

 

[wang1-dhcp-pool-wnt]expired unlimited

[wang1-dhcp-pool-wnt]q

 

 

 

 

配置保留地址的地址池

[H3C]dhcp server ip-pool wntbao           //创建保留ip地址池[高1] 

[H3C-dhcp-pool-wntbao]static-bind mac-address 20CF-3000-476A

[H3C-dhcp-pool-wntbao]static-bind ip-address 192.168.1.177

 

[wang1]dhcp server forbidden-ip 192.168.1.254     //配置排除的地址池

[wang1]dhcp server forbidden-ip 192.168.1.1 192.168.1.5   //排除一段地址

 

 

 

 

 

配置2网段分配的ip地址！

[wang1]dhcp server ip-pool 2

[wang1-dhcp-pool-2]network 192.168.2.0 24

[wang1-dhcp-pool-2]gateway-list 192.168.2.254

[wang1-dhcp-pool-2]dns-list 202.102.128.68

 

[wang1-dhcp-pool-2]expired day 30 hour 10 minute 10

[wang1-dhcp-pool-2]q

 

[wang1]dhcp server forbidden-ip 192.168.2.254

[wang1]dhcp server forbidden-ip 192.168.2.1 192.168.2.1

 

[wang1]display dhcp server forbidden-ip                  //查看排除的地址范围

IP Range from 192.168.1.1          to  192.168.1.5

IP Range from 192.168.1.254        to  192.168.1.254

IP Range from 192.168.2.1          to  192.168.2.1

IP Range from 192.168.2.254        to  192.168.2.254

 

设置ip地址---实现地址分配

[wang1]int e0/1

[wang1-Ethernet0/1]ip add 192.168.2.254 24

[wang1]int e0/0

[wang1-Ethernet0/0]ip add 192.168.1.254 24

 

 

 

Pc机尝试获取ip地址

[wang1]display dhcp server ip-in-use all  //查看已经获取的ip地址

Global pool:

 IP address       Client-identifier/    Lease expiration          Type

                  Hardware address

 192.168.1.177    20cf-3000-476a        Unlimited                 Auto:COMMITTED

 

 

 --- total 1 entry ---

 

 

Wang2尝试获取ip地址

[wang2]int e0/1

[wang2-Ethernet0/1]ip ad

[wang2-Ethernet0/1]ip address ?

  X.X.X.X      IP address

  bootp-alloc  IP address negotiated with BOOTP

  dhcp-alloc   IP address negotiated with DHCP

 

[wang2-Ethernet0/1]ip address dh

[wang2-Ethernet0/1]ip address dhcp-alloc ?

  client-identifier  Fill client-identifier of DHCP client with hardware

                     address

  <cr>       

[wang2-Ethernet0/1]ip address dhcp-alloc

 

 

 

二.分配不同网段的ip地址

 

 

使能DHCP

[Router] dhcp enable

配置DHCP服务器组中DHCP服务器的IP地址

[Router] dhcp relay server-group group-id ip ip-address

配置接口工作在DHCP中继模式

[Router-Ethernet1/1] dhcp select relay

配置接口与DHCP组关联

[Router-Ethernet1/1] dhcp relay server-select group-id

---

此处与win2003和Cisco不同。要想保留ip地址必须创建一个地址池。

并且一个地址池只能保留一个！
