华为交换机DHCP配置

1、交换机开启dhcp服务

[Huawei] dhcp enable

2、配置用户网关，并在接口下开启dhcp全局模式

[Huawei] interface vlanif 10

[Huawei-Vlanif10] ip address 192.168.10.254 255.255.255.0

[Huawei-Vlanif10] dhcp select global  选择全局dhcp类型

[Huawei-Vlanif10] quit 

3、创建地址池

[Huawei] ip pool vlan10

[Huawei-ip-pool-pool1] network 192.168.10.0 mask 255.255.255.0 

[Huawei-ip-pool-pool1] dns-list 114.114.114.114   配置DNS

[Huawei-ip-pool-pool1] gateway-list 192.168.10.254  配置网关

[Huawei-ip-pool-pool1] lease day 3   设置租约

4、保留 192.168.10.1-192.168.10.10 不下发

[Huawei-ip-pool-pool1] excluded-ip-address 192.168.10.1 192.168.10.10

 [Huawei] dis ip pool name vlan10 used 查看地址池ip使用情况

<Huawei>reset ip pool name pool1 192.168.2.1 回收IP地址192.168.2.1

5、 配置DHCP通过vlanif接口下的接口获取来获取地址

<Huawei> system-view  进入系统视图

[Huawei] interface Vlanif 20

[Huawei-Vlanif20]ip address 192.168.20.1 255.255.255.0  vlan地址

[Huawei-Vlanif20]dhcp select interface  选择基于接口的dhcp类型

[Huawei-Vlanif20]dhcp server excluded-ip-address 192.168.20.200 192.168.20.253  排除保

留的地址

[Huawei-Vlanif20] dhcp server static-bind ip-address 192.168.20.100 mac-address 5489-98b7-7378  绑定MAC静态IP

[Huawei-Vlanif20]dhcp server lease day 8 hour 0 minute 0  设置租约

[Huawei-Vlanif20]dhcp server dns-list 114.114.114.114  配置DNS

6、华为交换机配置dhcp中继

拓扑图

SW2配置：

vlan batch 10 20 50

dhcp enable

dhcp server group yukong

dhcp-server 10.3.50.50 0

interface Vlanif10

ip address 10.0.0.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 10.3.50.50

interface Vlanif20

ip address 20.0.0.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 10.3.50.50

interface Vlanif50

ip address 10.3.50.1 255.255.255.0

interface Vlanif10

ip address 10.0.0.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 10.3.50.50

interface Vlanif20

ip address 20.0.0.1 255.255.255.0

dhcp select relay

dhcp relay server-ip 10.3.50.50

interface Vlanif50

ip address 10.3.50.1 255.255.255.0

interface GigabitEthernet0/0/1

port link-type access

port default vlan 10

interface GigabitEthernet0/0/2

port link-type access

port default vlan 20

interface GigabitEthernet0/0/3

port link-type access

port default vlan 50

AR1配置：

dhcp enable

ip pool vlan10

gateway-list 10.0.0.1

network 10.0.0.0 mask 255.255.255.0

dns-list 114.114.114.114

ip pool vlan20

gateway-list 20.0.0.1

network 20.0.0.0 mask 255.255.255.0

dns-list 114.114.114.114

interface GigabitEthernet0/0/0

ip address 10.3.50.50 255.255.255.0

dhcp select global

ip route-static 10.0.0.0 255.255.255.0 10.3.50.1

ip route-static 20.0.0.0 255.255.255.0 10.3.50.1
