Xmit-Err on Cisco 9200

[przemyslaw turowski]

I have a problem: one of the interfaces disconnects from time to time. I am sending a screenshot of the errors with a request for help in solving the problem.

[MHM Cisco World]

It hardware issue 

Change cable fisrt 

If this not solve issue then 

Change NIC of server/pc connect 

If not solve issue then this port is damaged.

Sorry.

[MHM Cisco World]

Also check duplex in both side it can be issue.

[Leo Laohoo]

Post the complete output to the command "sh interface Gi1/0/35 controll". 

NOTE:  Do not post screenshots.

That is a very large number of collision frames. 

Is speed and duplex hard-coded on the switch?

[przemyslaw turowski]

Speed and duplex is auto:

Gi1/0/35 a-full a-1000 10/100/1000BaseTX

[MHM Cisco World]

friend I think it hardware issue 
cable or NIC 

[przemyslaw turowski]

Thank you very much.

[MHM Cisco World]

You are so so welcome

According to the output, there is a ton on collision.  

[johnlloyd_13]

hi,

what is the adjacent device on this port? is it a server?

try to hard code speed/duplex to 1000/FD on both the switch port and adjacent device.

[przemyslaw turowski]

It's notebook via Lenovo ThinkPad USB-C Dock.

[Leo Laohoo]

All of those laptops with USB-C docking station always comes with a USB-C-ethernet dongle.  Use that and see if the Xmitt error is still incrementing.  

I suspect the docking station is faulty.  I have seen numerous times.
