Chapter 5 Administering the Bridge Creating a Banner Step 3 Step 4 Step 5 Step 6 Step 7 Command ip name-server server-address1 [server-address2 ... server-address6] ip domain-lookup end show running-config copy running-config startup-config Purpose Specify the address of one or more name servers to use for name and address resolution. You can specify up to six name servers. Separate each server address with a space. The first server specified is the primary server. The bridge sends DNS queries to the primary server first. If that query fails, the backup servers are queried. (Optional) Enable DNS-based host name-to-address translation on your bridge. This feature is enabled by default. If your network devices require connectivity with devices in networks for which you do not control name assignment, you can dynamically assign device names that uniquely identify your devices by using the global Internet naming scheme (DNS). Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. If you use the bridge IP address as its host name, the IP address is used and no DNS query occurs. If you configure a host name that contains no periods (.), a period followed by the default domain name is appended to the host name 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 host name, the 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 bridge, 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 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 Configuration Fundamentals Command Reference for Release 12.2.
