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. This number is the total of available MAC addresses, including those used for other Layer 2 functions and any other secure MAC addresses. Learn how to configure port security on Cisco switches to prevent unauthorized network access and pass your CCNA 200-301 exam.

Offers 8-port, 16-port, 24-port, 48-port access and all ports support line-rate forward. H3C S5000V5 series switch supports IRF2 technology that connects multiple physical devices (up to 9) to a logical device, that is to say, users can manage and use these devices as a single device. IRF can bring the following benefits to the user： Simplify the management:Any one of the ports can be connected to any of the devices to login to a unifi. Support IP Source Guard, which can prevent illegal IP/MAC address spoof and DOS attack. Supports flexible queue scheduling algorithms, including SP(Strict Priority), WRR(Weighted Round Robin) and SP+WRR.

This article will delve into the application of industrial switches in environmental monitoring, explore how they can improve monitoring efficiency, data accuracy, and inject new vitality into environmental protection. Environmental monitoring of chassis components provides early-warning indications of possible component failures, which ensures a safe and reliable system operation and avoids network interruptions. Industries ranging from oil and gas production to water management to agriculture use Digi IoT technology to transmit data on environmental conditions and monitor the safety and performance of machines and systems. e reality is simple: data is the lifeblood of many organizations, and the data center has become the heart. IoT, or the Internet of Things, refers to a network of interconnected physical devices and objects that are embedded with sensors, software, and other technologies, enabling them to collect and exchange data over the Internet.

The most common link aggregation deployment in business networks is on uplinks between access-layer and distribution-layer switches. A floor or departmental access switch typically has many user devices connected to it. How should the access switch and aggregation/core switch be configured to allow two connection from access switch to core switch?This article provides a comprehensive explanation of link aggregation — covering LACP, static vs dynamic link aggregation, and MLAG (Link Aggregation Plus) — along with real configuration examples from Cisco and Huawei switches. In this article, I'm going to describe how to set up Link Aggregation between two managed switches to provide connectivity, redundancy, and expanded bandwidth. Link aggregation is a way of bundling a bunch of individual (Ethernet) links together so they act as a single logical link.

Ethernet frame in LANs or multi-link PPP in WANs, Ethernet MAC address) aggregation typically occurs across switch ports, which can be either physical ports or virtual ones managed by an operating system. These aggregation switches typically operate at Layer 2 or Layer 3 of the OSI model, depending on the network topology and configuration requirements. They support link aggregation protocols such as Link Aggregation Control Protocol(LACP) and Static Link Aggregation, which allow multiple physical. A Layer 2 access topology provides the following unique capabilities required in the data center: VLAN extension—The Layer 2 access topology provides the flexibility to extend VLANs between switches that are connected. The same layer 2 (L2) switch may be used in the access layer or the convergence layer in different network structures; for the same reason, the same layer 3 (L3) switch, in different applications, It may be used as an aggregation layer switch or as a core layer switch.
