Hi,
I would like to request for assistance/advice on the bug logs as shown below which found from the WS-C3850-24T on version 03.02.03.SE. During the incident, the switch was stuck/hung which unable to SSH or take control from the device via console which require hard reboot by pulling the power cable.
After restarted, the switch was back to normal and I would like to request for anyone that experiencing this issue might able to provide some guidance. Kindly informed that the log shows below was captured before hard reboot when console to the switch.
