After the capture is completed, the configuration file needs to be edited to remove text that is not required to configure a router. Then it can be pasted back into the router if needed.

The configuration file can be edited from a text editor such as Notepad. The following steps are used to edit the file:

•Select File > Open

•Find the captured file and select it

•Click Open

The lines that need to be deleted contain the following:

•show running-config

•Building Configuration…

•Current Configuration

•At the end of each of the interface sections, students should add no shutdown.

•To save the clean version, select File > Save.

Before the configuration is restored, any remaining configuration should be removed from the router by issuing the command erase startup-configuration. Use the reload command to restart the router.

HyperTerminal can be used to restore the configuration:

•Enter global configuration mode.

•Select Transfer > Send > Text File in HyperTerminal.

•Select the name of the file.

•Read the lines of the file as they are entered into the router.

•Observe for any errors.

•Press Ctrl-Zto exit global configuration mode after the configuration file is entered.

•Use the copy running-config startup-config command to restore the startup configuration file.
