ABSTRACT:
A system, method, and computer-readable medium for performing network system diagnostics is provided. The method includes obtaining a respective identification of a first target device and a second target device deployed in a network; iteratively querying neighbor devices of at least one node in a communications path between the first and second target devices, wherein the neighbor devices and the first and second target device may comprise heterogeneous network nodes; and generating a layer 2 path trace that comprises identification of network devices interconnected on a physical path between the first and second target devices. A computer-readable medium includes instructions for execution by a processing system, wherein the instructions are configured to perform the foregoing method. A system includes a data processing system including a processor device for executing a diagnostics engine implemented as a set of computer-executable instructions configured to perform the foregoing method.
