Most crc errors are physical layer related. Try swapping cables or choosing better quality cables. That is usually the case.

Hi Soulja,

I did that already but same error.

Thank you
What is connecting to these ports with the CRC errors? Have you double check duplex/speed setting on the switch and end devices?

Its just PC connecting to this Port..and configure as half duplex.
Why do you have them configured as half duplex? What setting do you have the port set to?

You need to configure the pc's interface the same as the port. 100/Full. Are the PC's auto negotiating to half duplex?
