ABSTRACT:
A network device is arranged to transmit a specific identification such as the device's MAC address in Next Pages of auto-negotiation and to determine a link status to be ‘down’ if ‘Next Pages’ containing that address are received by the same port. The invention avoids the use of signal detect pins for fiber optic links.
