The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Reporting Extracted Fields Through Flexible NetFlow feature allows Network-Based Application Recognition (NBAR) to send subapplication table fields to the collector through Flexible NetFlow.
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.
| Command or Action | Purpose | |
|---|---|---|
|
Step 1 |
enable Example: |
Enables privileged EXEC mode.
|
|
Step 2 |
configure terminal Example: |
Enters global configuration mode. |
|
Step 3 |
flow exporter exporter-name Example: |
Enters Flexible NetFlow flow exporter configuration mode. |
|
Step 4 |
option sub-application-table Example: |
Enables periodic sending of an options table that allows the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in flow records to application IDs. |
|
Step 5 |
exit Example: |
Exits Flexible NetFlow flow exporter configuration mode and returns to global configuration mode. |
The following example shows how to enable the periodic sending of an options table, which allows the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in the flow records to application IDs:
Device(config)# flow exporter FLOW-EXPORTER-1
Device(config-flow-exporter)# option sub-application-table
