Abstract
Embodiments provide systems, methods, and computer program products for inferring the switch port connectivity of discovered but unmanaged devices in a network without direct access to the devices. Embodiments operate by generating a physical address-to-port map based on collected operational data and then pruning the generated map based on switch port connectivity information and/or inferred link connectivity information. The switch port connectivity of discovered unmanaged devices is then generated or updated based on the pruned map. The switch port connectivity information can be used by various other tools to enable diagramming, asset inventory, and network planning, design, and optimization workflows.

A method for determining connectivity information of detected Internet Protocol (IP) devices in a network, comprising:
- generating a physical address-to-port map based on collected operational data;
- pruning the physical address-to-port map to generate a pruned physical address-to-port map, wherein said pruning comprises pruning the physical address-to-port map based on switch port connectivity Information and link connectivity information;
- and
- updating connectivity information of the detected IP devices based on the pruned physical address-to-port map.
A network management system for determining connectivity information of detected Internet Protocol (IP) devices in a network, comprising:
- an initialization module configured to generate a physical address-to-port map based on collected operational data;
- a pruning module configured to prune the physical address-to-port map based on switch port connectivity information and link connectivity information to generate a pruned physical address-to-port map;
- and
- a connectivity inference module configured to update connectivity information of the detected IP devices based on the pruned physical address-to-port map.
A method .for determining connectivity information of detected Internet Protocol (IP) devices in a network, comprising:
- generating a physical address-to-port map based on collected operational data;
- pruning the physical address-to-port map to generate a pruned physical address-to-port map, wherein said pruning comprises pruning the physical address-to-port map based on at least one of switch port connectivity information and link connectivity information;
- and
- updating connectivity information of the detected IP devices based on the pruned physical address-to-port map.
A non-transitory computer-readable storage medium having control logic recorded thereon that, when executed by a processor, causes the processor to perform a method for determining connectivity information of detected Internet Protocol (IP) devices in a network, the method comprising:
- generating a physical address-to-port map based on collected operational data;
- pruning the physical address-to-port map to generate a pruned physical address-to-port map, wherein said pruning comprises pruning the physical address-to-port map based on switch port connectivity information and link connectivity information;
- and
- updating connectivity information of the detected IP devices based on the pruned physical address-to-port map.
