HP NNMi (Hewlett Packard Network Node Manager i)

1. Network Discovery: HP NNMi automatically discovers network devices, including routers, switches, servers, printers, and other network elements, using various discovery protocols such as SNMP (Simple Network Management Protocol) and ICMP (Internet Control Message Protocol).

2. Topology Mapping: HP NNMi generates visual network topology maps that illustrate the connectivity and relationships between network devices. These maps help administrators understand the structure of the network, identify dependencies, and troubleshoot connectivity issues.

3. Performance Monitoring: HP NNMi monitors the performance of network devices and interfaces in real-time, collecting metrics such as bandwidth utilization, packet loss, latency, and error rates. Administrators can set thresholds and alerts to be notified of performance degradation or potential network outages.

Before diving into learning HP NNMi (Hewlett Packard Network Node Manager i), it's beneficial to have a solid foundation in several areas related to networking, system administration, and IT management. Here are some skills you should consider acquiring or strengthening:

1. Networking Fundamentals: Understanding of networking concepts, protocols, and technologies is essential for working with HP NNMi. You should be familiar with TCP/IP networking, OSI model, IP addressing, subnetting, routing, switching, VLANs, and network troubleshooting techniques.

2. Network Management Principles: Familiarity with network management principles, standards, and best practices is important for effectively using HP NNMi. You should understand concepts such as fault management, performance monitoring, configuration management, event correlation, and service assurance.

3. SNMP (Simple Network Management Protocol): Knowledge of SNMP and its operation is critical as HP NNMi relies heavily on SNMP for device monitoring and management. You should understand SNMP versions, MIBs (Management Information Bases), SNMP traps, polling, and SNMP-based monitoring tools.
