3064 RX input / CRC Error

[ChanyoungKim45540]

In 3064 with QoS and VPC for server virtualization configuration, input and CRC errors appear as shown below.
Which one should I check?
NIC replacement and cable replacement are complete.

Have you checked the below things,?

because this is an L1 issue you need to check multiple things.

Please go through with the below discussion.

Hello

Check cabling, speed/duplex settings,

why you config PO without LACP ??

Hello All, 

I am also facing same issue on my Nexus 3064 fiber sfp port and it is RX error and CRC issues. Steps I have taken but no luck. 

Step1: Change cable

step2: change SFP

step3: change the physical port

Strange finding: 

error generate on both switches in the RX section and TX is okay. I don't know how only errors generate on RX-RX rather than TX-RX
