What must be done if a pattern is deleted under the Classifier Type?

When a pattern is deleted under the Classifier Type, it is essential to specify another pattern for the Horizontal Probe. This is because the Horizontal Probe relies on specific patterns to effectively identify and classify devices within the Discovery process. If a pattern is removed, the probe no longer has the necessary reference to perform its function effectively. Therefore, updating the probe with another active pattern becomes crucial for maintaining the integrity and performance of the Discovery process.

By ensuring that the Horizontal Probe has a valid pattern, you enable continued operation and enhance the accuracy of the overall Discovery effort. This action helps to accurately identify and classify devices within the network, thus avoiding potential operational gaps that may arise from having no associated pattern.

In contrast, other options do not align with what is required in the event of a pattern deletion. For instance, the automatic removal of the Horizontal Pattern probe does not occur upon the deletion of a pattern, nor does the automatic switching to identification probes happen. Actions taken within the Discovery module generally require manual intervention to ensure that the system continues to function optimally. Additionally, while no further actions might seem appealing, it would lead to incomplete or inaccurate data collection during Discovery without updating the patterns.
