Finding duplex mismatches in copper based networks

摘要

In an embodiment, a method for finding duplex mismatches in a copper based network, includes: detecting late collisions and cyclic redundancy check (CRC) errors; if a port is in auto-negotiation and up in half-duplex and over threshold late collisions have been detected, then informing the user of a duplex mismatch and suggesting to the user to set the port to full duplex; and if the port is in forced full-duplex mode and over threshold CRC errors have been detected, then informing the user of a duplex mismatch and suggesting to the user to set the port to auto-negotiations mode.
