    How can we build a report to show Cisco ASA problem ACLs based on Net Insight information?


      It's great to finally be able to discover ACLs that are built improperly, or deployed in the wrong order, or negated by higher rules.


      But doing so by clicking through ten ACL's per screen at a time, and then having to hover over a warning icon and click in it's "Show Details" link isn't the enterprise way of operating that I know NPM 12.2 and NCM 7.7 can provide.


      Clicking through that way is an OK way to learn about one problem at a time, but it's inefficient.


      I'd prefer to see or build/use a Report that retrieves all Net Insight ACL problem information and shows it all in a single report.


      Do you know how we can make this happen--perhaps with SWQL in a Custom Report?  Or is there already a Report for this?  I've not found it yet.


      Finally, that report should be adjustable so it can include more than one ASA.  I have 80 ASA's at present, and outside of building Compliance Reports for them, I've no great way to see things about them as a group.



      How about it SWQL & SQL Custom Report Masters?  Is this a challenge, or is it easy-peasy-Mac & Cheezy?

          So I took this as an opportunity to quickly learn how these new tables are set up... all I can say is I regret that.  Getting down to the ACL was pretty straightforward but the way the rules are in the db is not making much sense to me.  First of all nothing in SWQL will actually show you the content of the line, so nothing will show you anything like 'permit  tcp  any4  host  192.168.xx.xx  eq  https', the whole thing just refers to them by their rule numbers.  What was more frustrating was that the rule numbering scheme seems not to add up.  It seems that the db starts counting at 0 but the UI adds 1 so things can start at 1.  Easy to offset for single values but when a rule is shadowed by multiple other rules they end up in a string and I can't add 1 to a string and get the intended results.


          On the plus side I did find out that if you click on the 1-10 it allows you to pick a number of items to display.  I think that selection doesn't seem to persist though, every time i go to a new ACL I was back to 10 per page.


          This is the best I can do for you, it looks up the latest config of each type, and lets you know the summary info about any ACL that has issues and generates a link to that page for you to look it over.  Go ahead and remove the comment marks if you want to see the madness that lies deeper but I fear it won't be too helpful.
