Course Overview
The OpenText™ Network Node Manager i (NNMi) is a core component of the OpenText™ Network Operations Management (NOM) solution. This four-day course about NNMi explains how to monitor and manage your enterprise networks. You will learn how to use a complex tool such as NNMi to gain visibility into their enterprise network devices and their interconnectivity, and identify the networking issues that may arise daily. You will learn how to troubleshoot such problems using the tools provided by NNMi and how to customize the tool to serve their purposes. The class provides an opportunity to develop hands-on experience in configuring the tool, discovering network devices, understanding their configuration, learning about their interconnections, gaining visibility into the traffic and load of the network, device, and interface failures, and managing events using NNMi. The course uses lectures and a series of hands-on labs to teach the course material.
Highlights:
- Describe the NNMi architecture
- Describe the various features and functionalities available with NNMi
- Understand how NNMi uses ICMP and SNMP to discover network devicesand their capabilities
- Use NNMI to effectively identify, prioritize, and resolve network-relatedevents
- Manage NNMi user access and permissions
- Describe the NNMi event sources and the stages of event processing
- Manage the event processing pipeline, customize events and their severity,add vendor trap definitions, block trap storms
