I have a MARS version 6.0 and have some problems with the Switchs Catalyst 6500, since long time ago those devices reporting every activity to the MARS but in these days the devices do not report to the mars, I check the config and i do not see nothing stranger, the mars show the following message:
"Cisco MARS detected an inactive reporting device that has not reported any event to MARS in the last hour. This may indicate that the device is not functioning properly"
But with the ASA and the Router it´s everything fine, and these devices can report to the mars. I think that the client did some changes but i can not see nothing.
I uploaded some files that show the config of devices in to the mars
