I am using a free trial which has a max of 5000 sensor and the issue appears to that each time I add a new device and run an 'Auto Discovery' only the ICMP is seen and not the actual interfaces (sensors) of my devices. Only one device is displaying live sensors which are not paused. I have other devices that just display the Ping and nothing else. I notice a connection refused error #10061 for each of the problem devices which are not displaying sensors.
Devices are (Cisco Nexus 5K and 7K routers)
Any help would be appreciated.
