Excessive undersized/giant packets. error on HP devices

Hi

I have HP 2610 and 2530 POE switches to which I connect my aps (AP 135, AP 105, AP 205).

Looking at the logs i see a lot of the following messages regarding the ports to which aps are connected:

 

 

W 07/23/15 15:32:47 00327 FFI: port 4-Excessive undersized/giant packets. See help.
W 07/23/15 15:32:27 00327 FFI: port 3-Excessive undersized/giant packets. See help.

 

 

The MTU size is set to "" in SAP MTU, so it should be set automatically.

Why I got those messages? 

What can I do?

Yes, I had read the article, but didn't read the link posted below

so setting the MTU size to 1500 is in this case a best practice, did I understood it correctly?

Yes, if you set the AP MTU to 1500, it should solve the problem.

 

Thanks,
