Cisco ACL Parser
>
Greeting all,
As I work with many firewalls, routers and switches, I have often wished I could parse the ACL’s into a spreadsheet. A few years back I found mangeek’s PIX ACL parser, it can be found at http://mangeek.com/portfolio/pixparser.html. I found it to be a great start to what I was looking for, however the script fell short when using object-groups and names. Also it would not parse the IOS based ACL’s. So a couple years back I made my own version of the tool. My tool was extremely ruff, but it did get the job done enough for my uses. Well, I decided to clean up the tool and fix some of the issues with object groups and names.
So I am now proud to release the ACL2CSV.PL version 0.02. The tool takes the name of a cisco configuration as an argument and then parses the data and returns a CSV file. The CSV file can then be used in your favorite spreadsheet tool for more analysis.
The tool does not do anything special with ACL’s nor does it fully look at how the ACL’s are used. But simply parses the ACL’s for review in a CSV format. I hope you enjoy the tool. I am going to doing more with object groups, inactive ACL’s and other features in the near future.
