Could be an IOS bug.

[Bachir Debili]

you have known the note cisco about this bug ?

thank for you reply

[Leo Laohoo]

No. 

I have several 2960X running the exact IOS with phones and APs on them.  I don't have error messages like that. 

But then again, I don't have some crazed configuration like that on my trunk ports either.

One can like you I have 40 this switch with IOS and I encounter this problem on a single knowing I do not have any device requiring POE, strange I'll open a case Cisco.

Thank for your feddback :)

Hi bochi75017,

Did you managed to open a TAC case for this? I do have the same issue using the same switches. The device connected to the port that has an error is a laptop with a docking station.

Hi ,

I also got the same error message of 2960X with Version 15.2(2)E6, but can not find any bug related.

Is there anyone know how to fix this issue? reload switch?
