We have an SN2100 switch that has worked flawlessly for 3 years, and then the other day it started to become unresponsive. There are no known infrastructure changes.
The switch has all green indicator lights, but will not forward traffic. The management interface also goes down.
A hard reboot will bring the switch up for a few min, but then it will go down again.
Any idea what may be happing here? and or any troubleshooting steps we should take to diagnose the problem.
