Comparing Configurations

I was reading David Bombal's "Cool IOS Commands Networking Tips Newsletter*" the other day and in it he has a link to a video showing you how to use ExamDiff to compare configurations. I had never heard of ExamDiff before and so decided to compare it to the file comparison tool that I use. I must say that ExamDiff is a very nice little tool. It has a lot of sophisticated functions and in my opinion it displays the differences in configurations nice and clearly, which is a must when you are scrolling through hundreds of lines of configuration at 3 in the morning and your eyes are stinging like hell. My only problem with it is that you need to upgrade to ExamDiff Pro at a cost to be able to compare directories.



Comparing directories of configuration files is a feature that is very important to me. I use this feature to download all the configuration files I am working on before a change and then download them after a change and compare directories to see the differences. So for the moment I will keep using Microsoft's WinDiff which allows me to compare directories and is still free. On the downside it has a lot more of a basic feel to it compared to ExamDiff (see below). Does anyone else have any configuration comparing utilities that they can recommend?


* If you have not subscribed to the newsletter then head over to http://www.configureterminal.com/ and subscribe. David Bombal is also the guy who produces the CCIE command memorizer and I was thinking of getting it. I have seen a couple of blogs asking people for their opinions on it, so I will join the club has anyone else used this tool and if so what did they think?

Hi,

Unix (Mac OSX, Linux, and so on) men like me would prefer vimdiff.

You can see and example here (sorry it is only in Spanish): http://www.the-evangelist.info/articulos/2008/08/11/vimdiff-editando-2-ficheros-diferentes/

Yea sorry I come from a Windows background so do not know much about the Unix world. Although I never thought I would, I must admit I wish I had learnt Unix it would help me so much with the Cisco side of things. Learning Unix will be my next project after CCIE although I do have a Mac at the moment so I will look into vimdiff, so thanks for the tip.

Hi David,

Your newsletters are very useful. I will get in touch with you to discuss the CCIE Command Memorizer later in the week.
