Have you ever struggled comparing two network configuration files?
Of course there exist numerous diff scripts and tools (Unix “diff” command, WinMerge…) but they are well suited for programming code or articles. When used on Cisco configuration files, they tend to flood relevant exception in a large amount of false positives, which might lead to mistakes and impact your productivity.
This tool addresses the problem with an approach that understands the hierarchical structure of Cisco configuration files and an output that facilitates comparison by reordering and aligning the files such that matching parts and corresponding sections are facing each other.
NB: this tool infers the hierarchical structure of configurations from their indentation (spaces at the beginning of the line), so it is essential that indentation of input files follows the format of a show run.
Because it is based almost only on indentation, this tool is platform agnostic: it can be used for configuration files of IOS, IOS-XE, IOS-XR, NX-OS...

great work, thx
Nice tool. I bookmarked it for use later, but it displays as "Cisco Tool" by default, due to the title. You couldn't give it a nicer title for other people wanting to bookmark it could you?
Thanks for the feedback, I will follow up on improving it :)
Thank you very much Philip for the feedback. We will take that into account.
Great tool , is anyway to download a copy into the local PC. , we have at times no internet , the local copy would be great way to help .... ?
Thank you Sam for the feedback.
The tool is still in a Beta phase and I'm afraid it is not yet possible to download a standalone version, but you are not the first one to ask for it and we are reviewing our options to see whether (and how) we could do that.
Can you advise what happens to the configuration files that are "uploaded to Cisco"?
Does it get stored and used by Cisco in any way?
Thanks for your answer in advance!
It is deleted, after running the tool and displayed the information, the customer files are deleted.
Have you considered (or will this work) with ASA firewall configurations?
Thank you for your interest in the tool. As it is will work well with any pair of configuration files having a hierarchical structure including the ASA ones.
This is a great tool. I would also like a local copy of it.
Great tool, this didn't work on ASA though
Great tool! is bookmarked now!
Any chance that the code for this will be released? In order to be able to include it in configuration review process?
I'm new to the community I must say Great tool! I just bookmarked!
