18.2.3 DHCP Server Configuration Example
Scenario :
To save configuration efforts of network administrators and users, a company is using
DCS-3950 series switch as a DHCP server. The Admin VLAN IP address is 10.16.1.2/24.
The local area network for the company is divided into network A and B according to the
office locations. The network configurations for location A and B are shown below.
PoolA(network 10.16.1.0) PoolB(network 10.16.2.0)

In location A, a machine with MAC address 00-03-22-23-dc-ab is assigned with a fixed IP
address of 10.16.1.210 and named as ‘management’.
Switch(Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip address 10.16.1.2 255.255.255.0
