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.

Table B-1 describes deep packet inspection (DPI)/L7 extracted fields and the CLI used to retrieve the value of the fields.
Table B-1 AVC DPI/L7 Extracted Fields
Notes
•In XE 3.7 and XE 3.8, the fields are exported using the field subApplicationValue (ID=45003). The field is encoded as {applicationID (4B), subApplicationID (2B), Value (Variable Len)} merged together. If the field is not observed, the size of the field is 6 and includes only applicationTag and subApplicationTag.
•The sub-application-table option template maps the extracted field ID to name and description, as follows:
–Extracted field ID: subApplicationTag (ID=97)
–Name: subApplicationName (ID=109)
–Description: subApplicationDesc (ID=110)
•All HTTP-based applications, such as YouTube, SharePoint, and so on, use the same sub-application ID, defined by the subApplicationID, as defined by the HTTP application.
