DHCP Server Quick Start Configuration Guide

Network configuration

As shown in Figure 1, department A uses VLAN 2, department B uses VLAN 3, and department C uses VLAN 4. Configure the core switch as a DHCP server for dynamic IP address assignment to the hosts in department A, department B, and department C.

Procedure

1.     Configure VLAN.

a.     From the left navigation pane, select Network > Links > VLAN.

b.     On the page that opens, click the create icon  to create VLAN 2.

c.     Add VLAN 2 to the VLAN list, and then click Apply.

d.     Click the edit icon  on the right of VLAN 2 to edit the settings of VLAN 2.

e.     Add GE1/0/2 to the untagged port list of VLAN 2.

f.     Select Configure VLAN interface at the IP address of the VLAN interface parameter.

g.     Assign IP address 192.168.5.1 and subnet mask 255.255.255.0 to VLAN-interface 2.

h.     Click Apply.

The system displays a success message if you configure VLAN 2 successfully.

i.     Configure VLAN 3 and VLAN 4 in the same way as you configure VLAN 2. Details are not shown.

2.     Create DHCP address pool.

3.     Configuring VLAN interfaces to operate in DHCP server mode.

a.     From the left navigation pane, select Network > Service > DHCP.

b.     On the page that opens, set the DHCP service type to DHCP server for VLAN-interface 2, VLAN-interface 3, and VLAN-interface 4. By default, an interface operates in DHCP server mode.

d.     Click Apply. The system displays a success message if you configure the advanced DHCP settings successfully.

4.     Save the configuration.

a.     From the left navigation pane, select Device > Configuration.

Verifying the configuration

Verify that the switch can dynamically assign an IP address from the desired subnet to Client A, Client B, or Client C.

To view the IP addresses assigned by the DHCP server, perform the following tasks:

1.     From the left navigation pane on the switch configuration page, select Network > Service > DHCP.

2.     Click Address pool at the upper right of the DHCP configuration page.

3.     Click the IP in Use tab.
