To troubleshooting tricky problems you may need to use a network analyzer, such as Wireshark. Best to familiarize yourself with it before you need to use it. You'll also need to configure a switch port into either “span port” or a “mirror port”.

Regularly monitoring the performance and availability of the LAN to identify and address any issues promptly. This may involve using network monitoring tools to track bandwidth usage, latency, and other key metrics.

A Local Area Network (LAN) admin is like the superhero of your school’s Wi-Fi. They make sure all your computers, printers, and gadgets can talk to each other and stay connected. They fix network problems, set up firewalls, and keep everything running fast and smooth so you can stream, game, and study without any hiccups.

One of the most important things is to ensure that no suspicious errors are left unresolved or delayed, as this can potentially result in a disaster and impact critical application. It is crucial for the administrator to promptly take on the task of troubleshooting the issue until it is resolved.

Network Administrator ensure performance, availability and security. Deploy tools to monitor network health and performance.

A LAN administrator also performs regular maintenance and upgrade tasks to keep the network running smoothly and securely. This includes backing up and restoring data, installing and updating software and firmware, patching vulnerabilities, replacing faulty hardware, and testing new features. A LAN administrator also plans and implements network changes and improvements, such as adding or removing devices, expanding or reducing the network scope, or upgrading the network architecture.

A manutenção da rede deve ser feita de forma continua, assim como qualquer outra área de tecnologia, adequando a rede aos novos padrões de mercado, atualizando equipamentos ultrapassados, criando rotinas de backups para prevenção contra catástrofes, acompanhar o desgaste dos equipamentos e manter-se sempre atualizado sobre novidades do mercado.

LAN administrators are responsible for the ongoing maintenance of the network infrastructure. This involves performing routine checks, applying updates, and ensuring that all components are operating at peak efficiency. Additionally, they play a pivotal role in planning and executing network upgrades, keeping the organization's technology infrastructure aligned with evolving business needs.

Prever el crecimiento futuro y planificar la infraestructura de red para garantizar que pueda escalar eficientemente satisfacciendo las necesidades cambiantes de la organización.

As a network administrator one of the primary roles is to keep records of the network's architecture, hardware configurations, and software settings.They document IP addresses, subnet details, routing protocols, firewall rules, and security measures, creating a comprehensive reference guide for troubleshooting and future planning.In parallel, the administrator dedicates efforts to proactive support functions. This encompasses monitoring network performance, promptly addressing issues, and conducting routine maintenance to guarantee optimal efficiency. Additionally, the administrator extends invaluable user support, swiftly resolving connectivity problems and providing assistance for diverse network-related challenges.

Before initiating any project, it is essential to engage in proper planning and design, accompanied by comprehensive and easily understandable network documentation. This documentation serves to uphold the credibility of the infrastructure and can be edited as needed in the event of changes or during troubleshooting processes.

Network documentation is the backbone of any relevant network architecture discussion. It is difficult to make changes to an environment, especially when talking with a large group of people if there is no understanding of what the architecture looks like.

Network documentation is important for the following reasons: Proper documentation can save you from time-consuming research to fix recurring problems. When everything is in place and everybody follows the same processes and procedures, consistency across the network helps to reduce problems and errors.

Documentation can make your job 1000 times easier, and making sure to update that documentation when changes are made is also key. When I started my first Network admin job, not only did I spend an entire week locked in the data center updating documents, I also went around and labeled the network racks with numbers so it was easier to find something. Instead of saying row 3, case 4, I put actual numbers on the cases so there was zero confusion.

Trabalhar em conformidade com as boas práticas é vital, pois, diversos profissionais já testaram e validaram algumas configurações e procedimentos, além de seguir normas regulamentadoras. Uma ótima ferramenta opensource que pode ajudar nessa situação é o SIEM Wazuh, ferramenta de código aberto que possibilita monitorar ativos, ações nos dispositivos, gerar alertas, listas configurações que não estão em conformidade, é importante que todo administrador de rede tenha o mínimo de conhecimento nessa ferramenta, que possibilita uma vasta lista de recursos.

Securing and ensuring compliance for the network is more than a task—it's a weighty responsibility. From implementing robust security policies and encryption to monitoring and protecting against threats, the goal is to create a digital fortress. Going beyond guidelines, it's about actively staying ahead of risks—thwarting hackers, tackling malware, and preventing unauthorized access. Embracing standards like ISO, NIST, or HIPAA isn't just a checkbox exercise; it's a commitment to a resilient network. It's about instilling confidence that the network is actively fortified against the complexities of the cyber world.

Network Administrator: Manages and oversees the organization's entire network infrastructure, which may include multiple locations. This role involves planning, implementing, and maintaining the overall network architecture, including WANs (Wide Area Networks) and interconnecting various LANs.

Additionally, a LAN network administrator communicates with the users of planned maintenance, service degradation and service restoration in a timely manner. Traffic engineering - a LAN administrator must engineer traffic through automation or manually,: depending on platform capability fo get the best service at any given time. This role is expected to manage TCP/IP stack hence a need to understand PC level networking, so they must be able to work with common Operating systems like linux, Windows and MacOS. They must know network% virtualisation at at server level and network level. The must have a pi(π) shaped skillset, thus they must have more than one area of speciality knowledge and broader interdisciplinary understading knowledge7.

A LAN administrator maintains and monitors a network once it has been developed while a network engineer is responsible for designing and implementing a network.

O foco de um administrador de LAN é a rede local com suas segmentações de VLANs locais, isso pode incluir a manutenção e monitoramento de todos os equipamentos diretamente conectados nessa rede local.

They generally will not enjoy system administration, nor have the time to learn how to write code. I think that knowing how to administer Linux and UNIX is a must to give network engineers more credibility. While knowing how to write code is certainly a skill worth having, I'd say there is a market for hardcore network engineers that understand the basics well, and can build themselves into an expert, especially on CLI.

A gestão de logs é uma prática essencial para administração de sistemas e redes, a consolidação desses dados tem desempenhado um papel importante para segurança, observabilidade dos sistemas e serviços sendo fundamental para resolução de problemas.
