IPFIX templates for AFM SIP events

Overview: IPFIX templates for AFM SIP events

The IP Flow Information Export (IPFIX) Protocol is a logging mechanism for IP events. This appendix defines the IPFIX Information Elements (IEs) and Templates used to log F5’s Application Firewall Manager (AFM) events related to the Session Initiation Protocol (SIP). An
IE
is the smallest form of useful information in an IPFIX log message, such as an IP address or a timestamp for the event. An
IPFIX template
is an ordered collection of specific IEs used to record one IP event, such as the acceptance of a SIP session.

About IPFIX information elements for AFM SIP events

Information Elements (IEs) are individual fields in an IPFIX template. An IPFIX template describes a single Advanced Firewall Manager (AFM) SIP event.

IANA-defined IPFIX information elements

IANA maintains a list of standard IPFIX information elements (IEs), each with a unique element identifier. The F5 AFM DNS IPFIX implementation uses a subset of these IEs to publish AFM DNS events. This subset is summarized in the table.

IPFIX enterprise information elements

IPFIX provides for enterprises to define their own information elements (IEs). F5 currently uses the following non-standard IEs for AFM DNS events:

IPFIX, unlike NetFlow v9, supports variable-length IEs, where the length is encoded within the field in the Data Record. NetFlow v9 collectors (and their variants) cannot correctly process variable-length IEs, so they are omitted from logs sent to those collector types.
