COMMAND LINE INTERFACE

dns-server

Use this command to specify the Domain Name System (DNS) IP servers available to a DHCP client. Use the no form to remove the DNS server list.

Syntax

dns-serveraddress1 [address2] no dns-server

•address1 - Specifies the IP address of the primary DNS server.

•address2 - Specifies the IP address of the alternate DNS server.

Default Setting

None

Command Mode

DHCP Pool Configuration

Usage Guidelines

•If DNS IP servers are not configured for a DHCP client, the client cannot correlate host names to IP addresses.

•Servers are listed in order of preference (starting with address1 as the most preferred server).

Example

Console(config-dhcp)#dns-server 10.1.1.253 192.168.3.19

Console(config-dhcp)#

4-108
