Cut-through, corruption and CRC-stomping

Corrupted frames are the devils spawn.  A few noisy links causing frame corruption can quickly degrade network performance, and troubleshooting them is getting harder.  These integrity errors generally occur when signal noise causes a binary ‘1’ to be mistaken for a binary ‘0’ or vice-versa.  This post takes a look at integrity errors and the impacts of corrupted frames in a cut-through switched network.  Throughout this post I’ll use the term ‘CRC errors’ term to refer to frame integrity errors which were detected by CRC comparison.
