Overview: Configuring IPFIX logging for CGNAT

You can configure the BIG-IP system to log information about carrier grade network address translation (CGNAT) processes and send the log messages to remote IPFIX collectors.
IPFIX is a set of IETF standards described in RFCs 5101 and 5102. The BIG-IP system supports logging of CGNAT translation events over the IPFIX protocol. IPFIX logs are raw, binary-encoded strings with their fields and field lengths defined by IPFIX templates.
IPFIX collectors
are external devices that can receive IPFIX templates, and use them to interpret IPFIX logs.

Assemble a pool of IPFIX collectors

Before creating a pool of IPFIX collectors, gather the IP addresses of the collectors that you want to include in the pool. Ensure that the remote IPFIX collectors are configured to listen to and receive log messages from the BIG-IP system.
You can create a pool of IPFIX collectors to which the system can send IPFIX log messages.

    The Pool List screen opens.
  2. Click

  3. In the
    Name
    field, type a unique name for the pool.
  4. Using the

    setting, add the IP address for each IPFIX collector that you want to include in the pool:
    1. Type the collector's IP address in the
      Address
      field, or select a node address from the
      Node List
      .
    2. Type a port number in the
      Service Port
      field.
      By default, IPFIX collectors listen on UDP or TCP port
      4739
      and Netflow V9 devices listen on port
      2055
      , though the port is configurable at each collector.

      .
  5. Click

Create an IPFIX log destination

A log destination of the
IPFIX
type specifies that log messages are sent to a pool of IPFIX collectors. Use these steps to create a log destination for IPFIX collectors.
  1. On the Main tab, click
    System
    Logs
    Configuration
    Log Destinations
    .
    The Log Destinations screen opens.
  2. Click
    Create
    .
  3. In the
    Name
    field, type a unique, identifiable name for this destination.
  4. From the
    Type
    list, select
    IPFIX
    .
  5. From the
    Protocol
    list, select
    IPFIX
    or
    Netflow V9
    , depending on the type of collectors you have in the pool.
  6. From the
    Pool Name
    list, select an LTM pool of IPFIX collectors.
  7. From the
    Transport Profile
    list, select
    TCP
    ,
    UDP
    , or any customized profile derived from TCP or UDP.
  8. The
    Template Retransmit Interval
    is the time between transmissions of IPFIX templates to the pool of collectors. The BIG-IP system only retransmits its templates if the
    Transport Profile
    is a
    UDP
    profile.
    An
    IPFIX template
    defines the field types and byte lengths of the binary IPFIX log messages. The logging destination sends the template for a given log type (for example, NAT44 logs or customized logs from an iRule) before sending any of those logs, so that the IPFIX collector can read the logs of that type. The logging destination assigns a template ID to each template, and places the template ID into each log that uses that template.
    The log destination periodically retransmits all of its IPFIX templates over a UDP connection. The retransmissions are helpful for UDP connections, which are lossy.
  9. The
    Template Delete Delay
    is the time that the BIG-IP device should pause between deleting an obsolete template and re-using its template ID. This feature is helpful for systems that can create custom IPFIX templates with iRules.
  10. The
    Server SSL Profile
    applies Secure Socket Layer (SSL) or Transport Layer Security (TLS) to TCP connections. You can only choose an SSL profile if the
    Transport Profile
    is a
    TCP
    profile. Choose an SSL profile that is appropriate for the IPFIX collectors' SSL/TLS configuration.
    SSL or TLS requires extra processing and therefore slows the connection, so we only recommend this for sites where the connections to the IPFIX collectors have a potential security risk.
