11.4 DHCP Configuration Example

Scenario 1:
Too save configuration efforts of network administrators and users, a company is using
ES4626/ES4650 as a DHCP server. The Admin VLAN IP address is 10.16.1.2/16. 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)
Device IP address
Default gateway 10.16.1.200
10.16.1.201
DNS server 10.16.1.202
WINS server 10.16.1.209
WINS node type H-node
Lease 3 days
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". (The interfaces in the following
configurations are wrong; "no switch" command is not available.)
Switch(Config)#service dhcp
Switch(Config)#interface vlan 1
Switch(Config-Vlan-1)#ip address 10.16.1.2 255.255.0.0
Switch(Config-Vlan-1)#exit
Switch(Config)#ip dhcp pool A
Switch(dhcp-A-config)#network 10.16.1.0 24
Switch(dhcp-A-config)#lease 3
Switch(dhcp-A-config)#default-route 10.16.1.200 10.16.1.201
