IS there any way a customers internet traffic can cause HCS errors on a cable modem Ethernet interface? What I mean is I had a customer who said he was seeing packet loss and so I looked at the numbers on the cable modem and there were a few HCS errors but the levels looked good and there were no CRC errors. However, when I went to ping the modem I did see the packet loss. The customer did find that he was saturating his network so that is why i am asking if his saturation can cause the modem connection to the CMTS to drop packets.
