Control the access to the switch ports
To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. In today's topic we will learn about switch port mode access and how its configuration is done on Cisco switches. This can be a security risk when users connect. In the following we explain the four methods (port-based, single, multi, and MAC-based) and we illustrate the usage scenarios for each one. [pdf]FAQs about Control the access to the switch ports

Optical module sensing distance
Light emitter and a receiver form the sensing elements of an Optical time-of-flight (ToF) long range proximity and distance sensing system. The emitter sends modulated light pulses. These are commonly known by various names, including LIDAR and time of flight sensors, although there is actually overlap in. Optical distance sensors perform different measurement tasks in various applications with varying requirements with regard to accuracy, resolution and size. This document describes the detailed functionality of ToF proximity systems, explains the trade-offs involved in a typical ToF system and provides a step-by-step design flow. [pdf]
