Domain Name Service Commands

58-4

Default Setting 

None

Command Mode 

Global Configuration

Command Usage 

• Domain names are added to the end of the list one at a time. 
• When an incomplete host name is received by the DNS service on this switch, 

it will work through the domain list, appending each domain name in the list to 
the host name, and checking with the specified name servers for a match.

• If there is no domain list, the domain name specified with the 

ip domain-name

 

command is used. If there is a domain list, the default domain name is not used.

Example

This example adds two domain names to the current list and then displays the list.

Related Commands 

ip domain-name (58-3)

ip name-server

This command specifies the address of one or more domain name servers to use for 
name-to-address resolution. Use the 

no

 form to remove a name server from this list.

Syntax
