Abstract
A method and apparatus of a device that determines transmit and receive skew times between pairs of lanes of an electrical interface of a network element is described. In an exemplary embodiment, the device receive a plurality of configurations corresponding to a plurality of electrical loopbacks that can each couple transmit and receive interfaces of the electrical interface via the plurality of lanes in different patterns. In addition, for each of the plurality of electrical loopbacks, the device couples this electrical loopback to the transmit and receive interfaces of the electrical interface and measures overall skew times for pairs of the plurality of lanes of the electrical interface. Furthermore, the device computes the transmit and receive skew times for the transmit and receive interfaces from the overall skew times.
