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

Distance between wiring cabinets
What is the minimum distance between enclosures, with doors that are facing each other? In EN60204-1:2006+A1:2009 section 11. 5 said " In the case where such parts are present on both sides on the access way, the clear width shall be at least 1. "Working space: The front clearance, side clearance, and height clearance requirements for electrical equipment that provide a safe area for maintenance, inspections, and other work. Dedicated space: The space equal to the width and depth of electrical equipment in addition to the space extending.

Fiber Optic Grating Settlement Monitoring
Learn how Fiber Bragg Grating Static Level Devices improve infrastructure safety through accurate, real-time structural settlement and deformation monitoring. Settlement and deformation of multi-purpose utility tunnels (MUTs) are critical factors affecting their structural integrity and service life; however, effective identification methods remain limited. This study proposes a comprehensive approach integrating Brillouin frequency domain analysis. This study presents an integrated automated monitoring system for foundation pits based on fiber Bragg grating (FBG) technology. The system enables real-time measurement of diaphragm wall horizontal displacement, internal forces in supports, differential settlement of concrete struts, soil heave at. [pdf]
