A multi-port Ethernet device having a MUX mode passing internal status signals (e.g., ACT, LINK, SPEED, FDUP, CS, TPJS, TPAPS, RS, and/or XS) for each of a plurality of Ethernet ports in parallel over a common set of external pins. The Ethernet device may be 'fixed' in a multiplexed mode such that the MUX mode is the only way in which internal status signals for each Ethernet port is transmitted external to the Ethernet device, or the Ethernet device may provide a MUX mode for status signal output in addition to otherwise conventional output modes (e.g., a parallel status signal output mode and/or a serial status signal output mode). In MUX mode, all desired internal status signals (e.g., all nine (9) standard Ethernet status signals) are time division multiplexed onto the common set of external pins one Ethernet port at a time.
