Abstract: A computer-implemented method for detecting fault conditions experienced by remote physical ports may include (1) identifying a network connection between a first physical port operating in a first communication mode and a second physical port operating in a second communication mode, (2) monitoring at least one count that identifies the number of block-sized transmission errors encountered by the first physical port, (3) determining that the second physical port has experienced a fault condition based at least in part on the count that identifies the number of block-sized transmission errors encountered by the first physical port and then, in response to determining that the second physical port has experienced the fault condition, (4) deactivating the network connection to avoid dropping network traffic directed to the network connection. Various other systems, methods, and apparatuses are also disclosed.
