FCS Rx errors

Hi All,

 

I have a ProCurve 498358-B21 6120G/XG Blade Switch connected in daisy chain. Its interface 'C1' gets FCS Rx errors. The value increments to a certain number and then stops. The count of FCS Rx errors doesn't go beyond it.

The interface 'C1' is connected to another 6120 Blade Switch. 

We have swapped the cable, but no luck. The errors increment and doesn't go beyond it.

Why does the errors doesn't go beyond 83,412,582. What does it mean?
