The switch then listens to the device naming exchange to learn a corresponding interface of the switch on which each particular (named) device is reachable, and associates each learned device name to the learned corresponding interface for that particular device. The switch then allows identity responses from only learned device names on their corresponding interface. In another embodiment, the switch also listens to an IP address assigning exchange on the trusted interfaces to learn IP addresses assigned to each particular device, and associates each learned IP address with a corresponding learned device name and its corresponding interface. The switch then allows address resolution responses from only learned IP addresses from their corresponding learned device names on their corresponding interface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layer-2 security for industrial automation by snooping discovery and configuration messages","description":"In one embodiment, a switch in a computer network listens to a device naming exchange on trusted interfaces to learn device names of devices reachable on interfaces of the switch.
