HUAWEI SWITCH S5700 - HOW TO

Configuring a basic DHCP server

HUAWEI SWITCH S5700 HOW TO



With this simple procedure we will show how to configure a global

address pool to allocate IP addresses for clients when the clients and

DHCP server (our S5700) are in the same network segment.

In our example we will assume a network scenario with one DHCP server,

one DNS server and two offices: SwitchA is the DHCP server, SwitchB and

SwitchC are access switches.

We will describes how to configure a global address pool. Address pool

100.1.1.0/24 consists of two network segments: 100.1.1.0/25 and

100.1.1.128/25. The IP addresses of the VLANIF interfaces on the DHCP

server are 100.1.1.1/25 and 100.1.1.129/25.

There are a few computers in network segment 100.1.1.0/25 and the

computer locations are fixed. The lease of an IP addresses in

100.1.1.0/25 is 100 days, the DNS address is 100.1.1.2 and the IP

address of the egress gateway is 100.1.1.126.

There are a few computers in network segment 100.1.1.128/25 and the

computers are often moved from one place to another. The lease of an IP

addresses in 100.1.1.128/25 is 2 days, the DNS address is 100.1.1.2

and the IP address of the egress gateway is 100.1.1.254.

The network environment is shown in the picture.

General infos and application environment



<SwitchA> system-view

[SwitchA] dhcp enable

1. Enable DHCP Enter the configuration view

Enable DHCP

2. Create the address pools

[SwitchA] ip pool 1

[SwitchA-ip-pool-1] network 100.1.1.0 mask 255.255.255.128

[SwitchA-ip-pool-1] dns-list 100.1.1.2

[SwitchA-ip-pool-1] gateway-list 100.1.1.126

[SwitchA-ip-pool-1] excluded-ip-address 100.1.1.2

[SwitchA-ip-pool-1] lease day 10

[SwitchA-ip-pool-1] quit

[SwitchA] ip pool 2

[SwitchA-ip-pool-2] network 100.1.1.128 mask 255.255.255.128

[SwitchA-ip-pool-2] dns-list 100.1.1.2

[SwitchA-ip-pool-2] gateway-list 100.1.1.254

[SwitchA-ip-pool-2] lease day 2

[SwitchA-ip-pool-2] quit

Enabling DHCP and configuring the address pool



3. Create vlans and assign physical interfaces

[SwitchA] vlan batch 10 20

[SwitchA] interface gigabitethernet 0/0/1

[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 10

[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 10

[SwitchA-GigabitEthernet0/0/1] quit

[SwitchA] interface gigabitethernet 0/0/2

[SwitchA-GigabitEthernet0/0/2] port hybrid pvid vlan 20

[SwitchA-GigabitEthernet0/0/2] port hybrid untagged vlan 20

[SwitchA-GigabitEthernet0/0/2] quit

Create vlans

Enter the interface view

Configure port type and assign vlan

Exit the interface view

Setting the address allocation mode on the

vlanif interfaces(1)



4. Configure the clients on vlanif 10 and 20

[SwitchA] interface vlanif 10

[SwitchA-Vlanif10] ip address 100.1.1.1 255.255.255.128

[SwitchA-Vlanif10] dhcp select global

[SwitchA-Vlanif10] quit

[SwitchA] interface vlanif 20

[SwitchA-Vlanif20] ip address 100.1.1.129 255.255.255.128

[SwitchA-Vlanif20] dhcp select global

[SwitchA-Vlanif20] quit

Enter vlanif view

Assign ip address to vlanif

Activate the global address pool distribution

Exit vlanif view

Setting the address allocation mode on the

vlanif interfaces(2)



7. Check the configuration on SwitchA [SwitchA] display ip pool
