Chapter 8: Configuring DHCP and DNS 

8.1 DHCP 

Dynamic Host Control Protocol (DHCP) allows users to automatically assign re-usable IP addresses to DHCP clients. 
The router software supports a full DHCP server implementation that assigns and manages IP addresses from 
specified address pools within the router to DHCP clients.  

8.1.1 Enabling DHCP Server 

By default, the DHCP server function is disabled on your device. To enable it, issue the 

service dhcp

 command. 

Use the 

no 

form of this command to disable the DHCP server feature. 

8.1.2 Enabling DHCP Address Conflict Logging 

By default, DHCP address conflict logging is disabled. To enable it, issue the 

ip dhcp conflict logging

 command. 

Use the 

no

 form of this command to disable the DHCP address conflict logging. 

8.1.3 Configuring DHCP Address Pool 

A DHCP address pool can be configured with a name that is a symbolic string (such as “Marketing”) or an integer 
number. Configuring a DHCP address pool also places you in DHCP pool configuration mode—identified by the 

(config-dhcp)#

 prompt—from which you can configure pool parameters (for example, the IP subnet number and 

default router list). 

To configure the DHCP address pool name and enter DHCP pool configuration mode, use the following command in 
global configuration mode: 

Router(config)# 

ip dhcp pool 

name  

Use the 

no 

form of this command to remove the configured DHCP address pool. 

8.1.4 Configuring the DHCP Address Pool Subnet and Mask 

To configure a subnet and mask for the newly created DHCP address pool, which contains the range of available IP 
addresses that the DHCP server may assign to clients, use the following command in DHCP pool configuration 
mode: 

Note: 

You cannot configure manual bindings within the same pool that is configured with the 

network 

command. To 

configure manual bindings, see the “Configuring Manual Bindings” section later in this chapter. 

Router(config-dhcp)# 

network 

A.B.C.D/M 

Use the 

no 

form of this command to remove the configured DHCP address pool subnet/mask.
