eNSP—DHCP的配置

网络拓扑如下：

【1】PC1、PC2的配置就是打开DHCP服务就可以。

【2】LSW2的配置：（其实就是简单的vlan配置）

<Huawei>
<Huawei>sys
[Huawei]undo info-center enable 
[Huawei]vlan 10
[Huawei-vlan10]quit
[Huawei]vlan 20
[Huawei-vlan20]quit
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access 
[Huawei-GigabitEthernet0/0/1]port default vlan 10
[Huawei-GigabitEthernet0/0/1]quit
[Huawei]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access 
[Huawei-GigabitEthernet0/0/2]port default vlan 20
[Huawei-GigabitEthernet0/0/2]quit
[Huawei]int g0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type trunk 
[Huawei-GigabitEthernet0/0/3]port trunk allow-pass vlan all

【3】LSW1的配置:（主要就是DHCP的配置）

<Huawei>
<Huawei>sys
[Huawei]undo info-center enable 
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk 
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/1]quit
[Huawei]dhcp enable 
[Huawei]ip pool vlan10     
## //地址池name为vlan10
[Huawei-ip-pool-vlan10]network 192.168.10.0 mask 24
[Huawei-ip-pool-vlan10]gateway-list 192.168.10.254
[Huawei-ip-pool-vlan10]dns-list 8.8.8.8
[Huawei-ip-pool-vlan10]excluded-ip-address 192.168.10.101 192.168.10.253
## //意思是地址池的地址范围除去192.168.10.101~192.168.10.253这个地址段 也就是地址池范围为192.168.10.1~192.168.10.100（地址分配是从大到小的）
[Huawei-ip-pool-vlan10]lease day 3   
## //租用时间为3天
[Huawei-ip-pool-vlan10]quit
[Huawei]vlan 10
[Huawei-vlan10]quit
[Huawei]vlan 20
[Huawei-vlan20]quit
[Huawei]int vlanif 10
[Huawei-Vlanif10]ip add 192.168.10.254 24
[Huawei-Vlanif10]quit
[Huawei]int vlanif 20
[Huawei-Vlanif20]ip add 192.168.20.254 24
[Huawei-Vlanif20]quit
[Huawei]int vlanif 10
[Huawei-Vlanif10]dhcp select global 
[Huawei-Vlanif10]quit
[Huawei]ip pool vlan20    
## //地址池name为vlan20
[Huawei-ip-pool-vlan20]network 192.168.20.0 mask 24
[Huawei-ip-pool-vlan20]gateway-list 192.168.20.254
[Huawei-ip-pool-vlan20]dns-list 8.8.8.8
[Huawei-ip-pool-vlan20]excluded-ip-address 192.168.20.100 192.168.20.253
[Huawei-ip-pool-vlan20]lease day 3   
## //租用时间为3天
[Huawei-ip-pool-vlan20]quit
[Huawei-Vlanif20]dhcp select global
