Displaying The Dns Configuration; Creating A Banner; Default Banner Configuration - Cisco 3845 - Security Bundle Router Software Manual

Chapter 5 Administering the Switch
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
command.

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 appears after the MOTD banner and before
the login prompts.
For complete syntax and usage information for the commands used in this section, see the Cisco IOS
Note
Configuration Fundamentals Command Reference, Release 12.2.
