Abstract: A network device includes a plurality of ports, a plurality of optical indicators, two or more packet processing circuits, and synchronization circuitry. The two or more packet processing circuits are to process packets communicated over the ports, each packet processing circuit to control a subset of the optical indicators to display status information relating to a subset of the ports. At least some of the status information is represented by blinking of the optical indicators. The synchronization circuitry is to synchronize at least one operational characteristic of the optical indicators among the two or more packet processing circuits.
