I am wondering if there is any documentation pertaining to the ISE API's handling limits. We are testing out an automated inventory integration and every now and then the dev is reporting that there is a connection error. The similar set up we are migrating from is currently running against ACS without issue.
I know firepower has a limitation of 120 messages per second before you get a 429 too many messages error. It also provides a 422 back if you send messages greater than 2 MB. Does ISE have any similar limitations that we have to work with? Has any one here run in to similar issues when trying to add/change NADs?
