The NAC API provides a method of inputting configuration into the NAC using a Perl script instead of typing it in manually. This is really nice if you have a large number of items to add or if you want to automate a particular process. One example would be to add the MAC addresses of printers to the device filter list. Another example would be to a method of automatically creating guest user accounts. Both of these features can be completed by the NAC Profiler and NAC Guest Server for larger deployments
There’s a good example of using the NAC API in the NAC Manager FAQ
