Hello,
Currently I am seeing a high TX/RX utilization on one of the links between 4507R and 3650. Below are the interface details.

I have already performed a software upgrade on 3650, looking at it as high CPU utilization. But still issue has been not resolved. We have another 3650 in the same location as the first one, with same IOS image, same kind of load but we don't see any high tx/rx loads and no output drops. I am confused as to why this specific switch is behaving like this. And this high utilization is only on the uplink from 4705R to 3650_1.
The 3650's are supporting IP cameras and Camera Workstations.
Current IOS versions are,
4507R - (cat4500e-ENTSERVICESK9-M), Version 15.2(2)E7
3650 - (CAT3K_CAA-UNIVERSALK9-M), Version 03.06.06E
Any help would be much appreciated.
