Scenario 1

Step 5. Map Services to Hostname.

DNS is essentially a means of mapping hostnames to IP addresses. The 7190 takes this mapping one step further by allowing the mapping of hostnames to services (IP address and service port). In this step the services that were created in Step 1 are mapped to the hostname created in Step 2.

hostnames create www

www siteservices

map westcoastsite:10.2.1.100:80

map eastcoastsite:10.2.2.100:80

Step 6. Save and activate the configuration.

The 7190 maintains two copies of configuration. One is the active copy of the configuration used by the name server function of the 7190. This configuration is accessed by all the show commands. The other copy is for in-work changes of the configuration. This configuration is accessed by all the config commands. This is the copy in which we have been entering the new configuration. In order to make the current in-work configuration active, the configuration must be committed using the commit command.

Save and Commit commands: The difference between the save and commit commands is often a source of confusion for new users. The save command is used to make a snapshot of the active configuration. The commit command is used to make the in-work configuration active. Once you have a good working configuration it is always a good idea to save a snapshot of this configuration before you do your next commit. This way if there is a problem with the new configuration you can use the restore command to revert to the previous configuration.
