Pg 04 Instructions: Project description 5 Marks Learning ✓ Solved

```html

Evaluate different SNMP tools, network statistics tools, and protocol analyzer for network management. The main objective of this project is to familiarize with network management and monitoring tools.

According to comparitech web site, selecting a network management and monitoring tool is a challenging task for network administrators due to various factors such as the huge number of tools in the market, the environment and the budget. You should select one tool among the best network monitoring tools using SNMP and perform the following tasks: 1. Describe the monitoring tool and provide two arguments to support your choice (0.5 mark). 2. Download and install the monitoring tool on your computer by providing a screenshot of its interface (0.5 mark). 3. Configure the SNMP management tool by selecting the SNMP version, credentials, community name, context and so on with screenshots for various selected parameters (0.5 mark). 4. Discover the network to identify connected devices by providing a screenshot of the network map (0.5 mark). 5. Describe three network analyses provided by the monitoring tool with three screenshots and explain their network parameters (3 marks). Use three different analysis categories like Performance/Top 10, Log/SNMP Trap, and Tools/SNMP MIB Walker.

Appendix: Example of network management tool interface based on SNMP, example of scan results of the network, example of network analysis that can be performed by the network management tool.

Paper For Above Instructions

Network management is an essential function for ensuring the efficient operation of IT infrastructure. It encompasses monitoring, managing, and optimizing network performance. Effective network management tools can provide insights into network performance, identify potential issues, and help maintain a secure environment. One widely recommended tool for network management is SolarWinds Network Performance Monitor (NPM). This paper describes this tool, justifying its selection, and covers installation, configuration, network discovery, and analysis tasks as specified in the project instructions.

Selection of the Monitoring Tool

SolarWinds NPM is selected for this project due to its robust features and ease of use. First, it offers comprehensive performance monitoring capabilities that include real-time visibility into network operations. This is crucial for quickly identifying performance bottlenecks or failures that may arise in large networks. Second, SolarWinds NPM provides advanced alerting mechanisms that notify network administrators about issues proactively, enabling faster response times and reduction in downtime.

Installation of SolarWinds NPM

After downloading SolarWinds NPM from the official site, I completed the installation process on my Windows machine. The installation was straightforward, guiding users through necessary steps to configure the database and server. Below is a screenshot of the SolarWinds NPM interface as seen after the installation has been completed:

Configuration of SNMP Management Tool

Upon successful installation, I configured the SNMP settings in SolarWinds NPM. I selected SNMP version 2c, set up community strings, and configured various other parameters required for managing the network through SNMP. One part of the configuration involved specifying the community name and access settings to ensure proper data collection. Below is a screenshot showing the setup for SNMP parameters:

Network Discovery

SolarWinds NPM allows for an automated network discovery process that identifies the devices connected to the network. I executed the discovery, which scanned the local subnet to map out devices, including servers, workstations, and network devices. The network map is beneficial for visualizing network architecture and for quickly identifying any unauthorized devices or misconfigurations. The following screenshot demonstrates the network topology that was discovered:

Network Analysis Using SolarWinds NPM

After finishing the setup and discovery tasks, I explored three distinct categories of network analysis provided by SolarWinds NPM:

1. Performance Analysis - Top 10 Devices

This analysis presents the top 10 network devices based on performance metrics such as bandwidth utilization and availability. It helps prioritize where to focus optimization efforts. The screenshot below illustrates the performance metrics:

2. Log Analysis - SNMP Trap

SolarWinds NPM provides an SNMP trap viewer that collects and displays notifications sent from network devices. Analyzing these traps enables administrators to be aware of network events, alarms, or configuration changes. The screenshot below show instances of received SNMP traps:

3. Tools - SNMP MIB Walker

The MIB Walker tool allows network administrators to browse MIBs in a tree structure and view real-time data for SNMP-enabled devices. This capability is essential for evaluating device status and performance. The screenshot below presents the MIB walker usage:

Conclusion

The implementation and evaluation of SolarWinds Network Performance Monitor provided valuable insights into its capabilities as a network management tool. Through the selection, installation, configuration, network discovery, and analysis phases, it was illustrated how SolarWinds NPM effectively assists in capturing and representing network data necessary for informed decision-making by network administrators.
