Creating a Banner
default domain name is the value set by the ip domain-name global configuration command. If there is
a period (.) in the host name, Cisco IOS software looks up the IP address without appending any default
domain name to the host name.
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 wireless device, 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.
Note When DNS is configured on the wireless device, the show running-config command sometimes
displays a server IP address instead of its name.
Creating a Banner
You can configure a message-of-the-day (MOTD) and a login banner. The MOTD banner appears 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 appears on all connected terminals. It appears after the MOTD banner and before
the login prompts.
Note For complete syntax and usage information for the commands used in this section, refer to the Cisco IOS
