Packet loss Issue

Hi All,

​

I am facing connectivity to one of my device (Access control device). So, basically, I am getting high packet loss to one of my IP. Tried changing the cables, ports but nothing seem to work. Tried restarting the device nothing changed. No packet loss or connectivity issue to Gateway IP and utilization is also normal. The topology is Wifi -> Controller -> Core Switch -> Distribution Switch -> Directly connected to device. I have even tried connecting the device directly to my laptop, connectivity is perfect and no drops. Please help!
