5.2.3 Managing configuration files using TFTP
The active configuration uses RAM and the default location for the startup configuration is
NVRAM. Students must understand the differences between RAM, ROM, NVRAM, and flash.
If the configuration is lost, there should be backup copies available. The backup configuration
can be stored on a TFTP server. The copy running-config tftp command can be used
to do this.
The steps to copy to a TFTP server are as follows:
•
Enter copy running-config tftp
•
Enter the IP address of the TFTP server at the prompt
•
Enter the name to assign to the configuration file
•
Answer yes each time to confirm the choices
The steps to copy from a TFTP server to restore the configuration file are as follows:
•
Enter copy tftp running-config
•
Select a host or network configuration file at the prompt
•
Enter the IP address of the TFTP server where the config file is located
•
Enter the name of the config file or accept the default name
•
Confirm the configuration filename and the server address
Make sure students realize that there are other ways to back up a configuration file. Other
methods will be discussed in later sections. It is important for students to understand this
process and all the procedures that are explained. It is most important for students to
understand that backups are an important part of network management.
5.2.4 Managing configuration files using copy and paste
Another way to create a backup copy of the configuration is to capture the output of the show
running-config command. The output can be copied, pasted into a text file, and saved to
create an alternate backup copy. However, the file will need to be edited before it can be used
to restore configuration to a router.
To capture the configuration in HyperTerminal, students should perform the following tasks:
•
Select Transfer > Capture Text
•
Specify the name for the text file
•
Select Start
•
Use the show running-config command to display the configuration
•
Press the Spacebar when each -More- prompt appears
