On a few of our routers (used as terminal servers) and a switch or two, we receive non-stop messages in the failed attempts of our ACS 3.2 and ACS 2.6 systems. The failed attempts usually contains the warning message and other items that wouldn't normally be passed on to the ACS server. The authentication to these systems works fine but these erroneous messages are filling up the failed attempts log on our ACS systems. Anyone have any ideas?
