Next, let's configure our overall network topology, (the prototype of the network topology diagram, and a lot will be added later)
In the first step, we configure the DHCP relay of the general network topology:
Let's take a look at my prototype network design topology:
This is the prototype of my network design
The following directly configures the DHCP relay of the network:
First configure the vlan and IP of SW1 to set the gateway of the server:
The device is running!
Configure the basic configuration first:
Sw1: Configure the configuration of sw2: Configure the configuration of sw2:
<Huawei>sys（进入配置模式）
[Huawei]sys sw1（改名）
[sw1]un in en（关闭提示）
[sw1]vlan batch 2 3 4（创建vlna 2 3 4）
[sw1]display this （显示配置）
#
sysname sw1
#
undo info-center enable
#
vlan batch 2 to 4
#

#
return
[sw1]dhcp enable （开启DHCP配置）
[sw1]int GigabitEthernet 0/0/3（进入端口3）
[sw1-GigabitEthernet0/0/3]port link-type trunk（配置端口为主干模式）

Configure the following sw4 below:
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys sw4
[sw4]int g
[sw4]int GigabitEthernet 0/0/1
[sw4-GigabitEthernet0/0/1]port link-type trunk

The above is the basis for us to configure DHCP and even all network configurations
Let's configure the IP of our vlan as the gateway of the server:
Configure sw1:
<sw1>sys
Enter system view, return user view with Ctrl+Z.
[sw1]int g
[sw1]int GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw1-GigabitEthernet0/0/1]q
[sw1]int Vlanif 2
[sw1-Vlanif2]ip ad 192.168.2.254 24
[sw1-Vlanif2]q
[sw1]int v
[sw1]int Vlanif 3
[sw1-Vlanif3]ip address 192.168.3.254 24
[sw1-Vlanif3]q
[sw1]int Vlanif 4
[sw1-Vlanif4]ip address 192.168.4.254 24
[sw1-Vlanif4]q
[sw1]Let's configure sw2:
<sw2>sys
[sw2]int g
[sw2]int GigabitEthernet 0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw2]int Vlanif 2
[sw2-Vlanif2]ip ad 192.168.2.254 24
[sw2-Vlanif2]q
[sw2]int Vlanif 3
[sw2-Vlanif3]ip ad 192.168.3.254 24
[sw2-Vlanif3]q
[sw2]int Vlanif 4
[sw2-Vlanif4]ip ad 192.168.4.254 24
[sw2-Vlanif4]q
[sw2]
