Configuration Examples

Manual Bindings Configuration Example

The following example creates a manual binding for a client named Mars.cisco.com. The MAC address of the client is 02c7.f800.0422 and the IP address of the client is 172.16.2.254.

ip dhcp pool Mars host 172.16.2.254

hardware-address 02c7.f800.0422 ieee802 client-name Mars

Because attributes are inherited, the previous configuration is equivalent to the following:

ip dhcp pool Mars

host 172.16.2.254 mask 255.255.255.0 hardware-address 02c7.f800.0422 ieee802 client-name Mars

default-router 172.16.2.100 172.16.2.101 domain-name cisco.com

dns-server 172.16.1.102 172.16.2.102 netbios-name-server 172.16.1.103 172.16.2.103 netbios-node-type h-node

Cisco IOS DHCP Client Example

Figure 15 shows a simple network diagram of a DHCP client on an Ethernet LAN.

Cisco IOS

DHCP client

10.1.1.1

E2ethernet

Cisco IOS

DHCP server

E1 42327

On the DHCP Server, the configuration is as follows:

ip dhcp pool 1

network 10.1.1.0 255.255.255.0 lease 1 6

On the DHCP client, the configuration is as follows on interface E2:

interface Ethernet2 ip address dhcp

This configuration allows the DHCP client to aquire an IP address from the DHCP Server through an Ethernet interface.
