About 27. Network Management

Network management encompasses monitoring, configuring, and maintaining network infrastructure to ensure availability, performance, and security aligned with organizational objectives. The FCAPS model (Fault, Configuration, Accounting, Performance, Security) provides a structured framework, while SNMP remains the dominant protocol for collecting metrics and issuing commands through MIB-defined objects, despite known security weaknesses mitigated by v3 encryption and community string hardening.

Modern approaches supplement SNMP with streaming telemetry, NETCONF/YANG model-driven configuration, and AI-powered anomaly detection to handle scale and complexity beyond traditional polling limits. Open-source tools like Prometheus/Grafana, commercial NMS platforms, and cloud-native observability stacks reflect convergence of networking and DevOps practices, emphasizing automation, declarative intent, and holistic visibility across hybrid infrastructures as manual CLI management becomes unsustainable.
