Devices connected to 2960x lose connection

Hi Guys,

I have a strange problem with my new WS-C2960X-24PD-L. I have installed IOS version 15.2(2)E5.

When I connect my laptop to any port on the switch, everything is ok. Once I unplug my laptop and plug it back into the same port, the network card on my laptop disconnects (enabled - network cable unplugged). During that period the light on my switchport stays green. Nothing seems to happen on switch level.

When I wait for +- 15min, the situation seems to restore by itself.

The port configuration on the switch is nothing exotic. Just a port in a specific vlan.

We have tried another laptop, with the same result, we have tried another switch (same type, bought at the same time, same IOS) also with the same result.

I still need to do some more troubleshooting. But any ideas already? 

Thanks,

joris

Hi,

Try upgrading the IOS to a different version and test again.
