If you use the switch IP address as its hostname, the IP address is used and no DNS query occurs. If you

configure a hostname that contains no periods (.), a period followed by the default domain name is

appended to the hostname before the DNS query is made to map the name to an IP address. The default

domain name is the value set by the ip domain-name global configuration command. If there is a

period (.) in the hostname, the Cisco IOS software looks up the IP address without appending any default

domain name to the hostname.

To remove a domain name, use the no ip domain-name name global configuration command. To

remove a name server address, use the no ip name-server server-address global configuration

command. To disable DNS on the switch, use the no ip domain-lookup global configuration command.

Displaying the DNS Configuration

To display the DNS configuration information, use the show running-config privileged EXEC

Creating a Banner

You can configure a message-of-the-day (MOTD) and a login banner. The MOTD banner displays on

all connected terminals at login and is useful for sending messages that affect all network users (such as

impending system shutdowns).

The login banner also displays on all connected terminals. It is displayed after the MOTD banner and

before the login prompts.

For complete syntax and usage information for the commands used in this section, refer to the Cisco IOS

Configuration Fundamentals Command Reference for Release 12.1.

This section contains this configuration information:

The MOTD and login banners are not configured.
