Device Sensor

Device Sensor is a network visibility feature that enables switches to collect and analyze information about connected endpoints through various discovery protocols including DHCP, LLDP, and CDP. It provides intelligent filtering and processing capabilities to extract relevant device attributes such as device type, operating system, user identity, and network behavior patterns. This information is essential for network access control, security policy enforcement, and asset management, allowing administrators to make informed decisions about device authorization and network segmentation.
