  • Connect to the equipment (telnet, ssh, …)
  • Run ”show” commands – config, inventory, ...
  • Collect, filter/format data
  •  Retrieve the resulting config files
  • CVS check-in the changes
  • Generate a diff from the previous version
  • E-mail the diff to a mail address (individual or group) 

 How does it work?



What can you use it for?

  • Track changes in the equipment configuration

  • Track version changes in the OS (IOS, CatOS versions)
  •  Recover from accidental configuration errors

Case Studies


Knute Weicke

Security Head, IT

Fellowes Inc, USA



Altnix was an instrumental partner in two phases of our Security ISO needs. The first being a comprehensive developed Service/Ticketing system for our global offices. The second being that of an Asset Management tool that ties all assets into our Ticketing systems to close a gap that we had in that category. They are strong partners in working towards a viable solution for our needs



The Altnix team was very easy to work with and resolved our needs in a timely manner.  Working with Altnix, allowed us to focus on our core business while they handled the technical components to help streamline our business tools.  We have found a strategic partner in Altnix
