I understand that there are collisions in half duplex due to the nature of Ethernet here - having to see if it is clear to transmit first. What I don't understand is why there are runt frames that are exactly the same number as the input errors. I have tried moving the cable to another switchport and the same issue - at least the switch is not a problem now.
A runt frame is a packet that is less than 64 bytes with a bad CRC - collisions would cause this, but so many?? -----Original Message----- From: Steven A.
