Information About Reporting Extracted Fields Through Flexible NetFlow

Subapplication Table Fields

Use the option sub-application-table command to send an options table periodically to the collector, thereby enabling the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in the flow records to application IDs.
