Introduction Effective network management requires a solid understanding of key configurations that enhance security, performance, and scalability. Three critical concepts—VLAN, VRF, and SNMPv3—form the backbone of modern network infrastructure, enabling segmentation, isolation, and secure monitoring. Learning Objectives Understand VLANs and their role in network segmentation. Learn how VRF isolates routing tables for multi-tenant environments. Configure SNMPv3 for secure network monitoring. …

Il protocollo SNMP, acronimo di Simple Network Management Protocol, è da decenni uno strumento fondamentale per la supervisione e la gestione dei dispositivi di rete. In questo articolo mettiamo a confronto SNMPv3 e SNMPv2c

À l'aide de Wireshark, découvrez les différences entre SNMPv3 et SNMPv2c afin de choisir le protocole le plus adapté pour sécuriser votre supervision.
