HP switch config with errors

Hi Experts,

I have some problems with a HP Switch.
The switch is HP 2510G-24 J9279A.

I have a lot of errors on this switch all on port 21.
See the picture.

CRC errors
Can you help me to solve this errors and can you explain what this errors mean ?

Every HP switch I've ever worked with will show this, even when there are no issues at all.

Manually set the speed/duplex on the switch port and the device which is connected to port 21 and the errors should stop.

Whether the duplex is ok or not - try it.  This is what usually works.

Why go to the expense of changing the switch if there's maybe a simple solution to try first?

because CISCO is more reliable then HP.
But ok, I will test the cables and plugs and the config mode.

Hmmm why do you say that? I'm certified in both - neither is specifically more reliable.

Don't worry about testing cables, etc, just set the speed/duplex and clear the logs.
