IPFIX Templates for AFM DNS Events
Overview: IPFIX
templates for AFM DNS 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) DNS events. 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 denial of a DNS query.About IPFIX information elements for AFM DNS events
Information Elements (IEs) are individual fields in an IPFIX template.
An IPFIX template describes a single Advanced
Firewall Manager (AFM) DNS 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.
About individual IPFIX templates for each AFM DNS event
This section enumerates the IPFIX templates that F5 uses to publish
AFM DNS Events.
