CRC Errors and GBICs on the Catalyst 3500XL Series

All of my Cisco Catalyst 3500 series XL switches are recording input cyclic redundancy check (CRC) errors on their uplink port to the commander switch. I am using GigaStack Gigabit Interface

Converters (GBICs). Why am I getting these errors?

Re: CRC Errors and GBICs on the Catalyst 3500XL Series

When there are more than two members in a cluster (stack), the Gigabit interface operates at half-duplex. Since collisions can result at half-duplex, some CRCs errors are normal.
