Config Archive 1

By certskills June 1, 2016 09:05

Even since the very first version of the CCNA R&S exam back in 1998, the exam topics included something that made people think that they needed to be ready to use the copy command to copy IOS files and config files to an external server. This latest post lets you practice configuring a newer feature that lets you configure a router to automatically create copies of the configuration on an external server using an archive process. And yes, it’s new in the new exam topics Cisco released in May 2016 (at least in my interpretation of the words).


For this lab, you will use a single router, just for simplicity. Basically, you will use the router’s own flash memory as the archive storage; normally you would use some external server, like an FTP or TFTP server. Regardless, for this lab, you will set up the new archive location in flash, and define a few other parameters for the archive process, including automatic backup of the configuration.

The specific rules for this lab are:

  • Use the mkdir flash:/csarchive EXEC command to create a directory in flash. This directory will be used as the location to store configuration archives.
  • Configure the archive to use the flash memory ‘csarchive’ directory (the directory you just created)
  • Configure the archive to save a maximum of 3 archive files
  • Configure the archive function to create a new configuration archive every 1 minute

Configuring the archive function is not difficult once you know the commands. However, you should look for a spare router on which to test your configuration. To test, once configured, repeatedly use the show archive command to see the current archives. To create a new archive, issue the archive config EXEC command. Also, because of the very low archive timer, you should see new archives created every minute.

Answer on Paper, or Maybe Test in Lab

Next, write your answer on paper. Or if you have some real gear, or other tools, configure the lab with those tools.

To test your solution if you happen to try it with CML/VIRL or real gear, you can verify that the archiving is working by issuing the show archive command which shows both the configuration and the current archive files created.


Do this Lab with Cisco’s CML (Formerly VIRL)

You can do these labs on paper and still get a lot out of the lab. As an extra help, we have added files for Cisco Modeling Lab – Personal (CML-P). CML-P replaces Cisco Virtual Internet Routing Lab (VIRL) software, in effect serving as VIRL Version 2.

Below, find two files: a file useful with CML-P and another useful with VIRL. (Note that the CML-P file has a .yaml filetype, while the older VIRL file has a VIRL filetype.) Once the file is loaded, CML-P or VIRL will create a lab topology similar to this lab’s topology, with the initial configuration shown in the lab as well.

All interfaces in topology match the lab figure.
