Configuring a basic DHCP server
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.

Configuring a basic DHCP server
<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

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)
