华为DHCP配置案例 – 六安创世纪网络工程

1.基于接口DHCP服务器配置

网络拓扑基于eNSP如下图

AR1作为DHCP服务器，提供DHCP服务，在接口GE0/0/0启动基于接口的DHCP

2. 基本DHCP服务器配置

sysname DHCP_Server
#
dhcp enable
#

#
interface GigabitEthernet0/0/0
 ip address 192.168.1.1 255.255.255.0 
 dhcp select interface
 dhcp server dns-list 8.8.8.8 8.8.4.4
 dhcp server lease day 3 hour 0 minute 0 
 dhcp server static-bind ip-address 192.168.1.100 mac-address 5489-9856-0D0
 dhcp server excluded-ip-address 192.168.1.1 192.168.1.10
 dhcp server domain-name hao0564.com
#

测试客户端可以成功获取ip地址为：192.168.1.253，华为的DHCP服务是从大数到小数

3.基于全局多网段配置DHCP服务器

交换机LSW3配置如下：

[Huawei]sysname LSW3 命名交换机名称
[LSW3]vlan batch 10 20 创建vlan 10 20
#
interface Ethernet0/0/1
 port link-type access
 port default vlan 20
 stp edged-port enable 开启stp边缘端口
#
配置接口interface Ethernet0/0/1为vlan10
#
interface Ethernet0/0/1
 port link-type access
 port default vlan 20
 stp edged-port enable
#
配置接口interface Ethernet0/0/3为vlan20
#
interface Ethernet0/0/3
 port link-type access
 port default vlan 10
 stp edged-port enable
#
配置交换机LSW3上行接口为Trunk口，允许所有vlan通过
#
interface Ethernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#

交换机 LSW2配置如下：

[Huawei]sysname LSW2
[LSW2]vlan batch 10 20
GigabitEthernet0/0/2接口配置
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#
创建vlan接口ip地址
#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0
#

#
interface Vlanif20
ip address 192.168.20.1 255.255.255.0
#

在交换机 LSW2上配置 DHCP服务器

[LSW2]dhcp enable
创建地址池ip pool vlan10如下：
#
ip pool vlan10
 gateway-list 192.168.10.1
 network 192.168.10.0 mask 255.255.255.0
#
创建地址池ip pool vlan20如下：
#
ip pool vlan20
 gateway-list 192.168.20.1
 network 192.168.20.0 mask 255.255.255.0
#
进入vlan接口配置
#
interface Vlanif20
 ip address 192.168.20.1 255.255.255.0
 dhcp select global
#

#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0
 dhcp select global
#
