4.1.2. Deployment Steps

To ensure the proper functionality of the deployed use case, it is crucial to meticulously follow the steps outlined. Keep in mind that these steps may vary based on the specific requirements and needs of your case.

Below, you will find a breakdown of both mandatory and optional steps, with the understanding that their applicability depends on your unique circumstances.

Architecture

  • Architecture: This section outlines the nodes necessary for the functioning of the use case, providing essential information related to its architecture. You can find a detailed explanation of the deployment of each of the nodes in Deployment and basic configuration.

Node Configuration

  • ON Analytics Configuration: ON Analytics is the node that is responsible for managing OpenNAC Enterprise data. Since Visibility relies primarily on data collected from the network, it is important to configure this node correctly.

  • Network Device Configuration: Most sources of Visibility involve configuration by network devices to provide information to OpenNAC Enterprise. This could involve configuring a Port Span, setting up SNMP traps, implementing DHCP Relay, and similar actions.

Optional:

  • ON Sensor Configuration: If our use case involves deploying ON Sensor nodes for network traffic sniffing, it’s essential to correctly configure these nodes.

Administration

  • Visibility Policies: These assist in regulating network visibility events and determining the corresponding actions (post-conditions), such as executing plugins to enhance profiling.

Optional:

  • Profiling Rules: Profiling is a crucial aspect of the visibility use case, providing insights into the connected devices on the network. To enhance and fine-tune profiling to its fullest potential, creating custom rules may be necessary.

  • Business Profiles Creation: In a network where visibility is being done, a lot of information is collected, and a large number of devices are discovered. To have everything well organized in the system, it might be interesting to create several business profiles.

  • Plugins Configuration: Visibility plugins are executed on network devices, providing more precise information about them. The increased details about a device contribute to higher accuracy in its profiling.

  • SNMP Traps Configuration: In the case of using SNMP Traps to discover new devices, it will be necessary to activate this functionality in the Administration Portal.

Operation

  • Operation: In this step, you will start operating the use case and checking that all the functionalities are working as expected. If you find unexpected behavior, refer to the troubleshooting section to understand and fix the issue.

Monitoring

  • Monitoring: See how the data is being ingested and saved in ON Analytics. To check this, open the different visualizations available for this use case.
