Hello, dear experts!
There was a program called Nipper, which could analyze cisco cfg files and make a html report. It was pretty useful to quickly understand network configuration and analyze network infrastructure. Unfortunately I guess this program doesn't supported anymore. Does anybody know any other program, which can analyze cisco cfg file and make graphical reports, including network infrastructure and security risks.
You can download an evaluation version of several of the licensed products (Cisco Prime LMS or Solarwinds Orion Network Configuration Manager for example) that include analysis and reporting on your configurations' soundness and compare them against best practices and standard vulnerability and compliance standards.
Here is a listing of the available LMS reports.
See here for the NCM coverage.
These, and any of the reputable tools, will require a purchased license for long term use.
