You can configure the BIG-IP® system to log information about DNS denial-of-service (DoS) events and send the log messages to remote IPFIX collectors.
IPFIX is a set of IETF standards. The BIG-IP system supports logging of DNS DoS 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.
The configuration process involves creating and connecting the following configuration objects:
|Object to create in implementation||Reason|
|Pool of IPFIX collectors||Create a pool of IPFIX collectors to which the BIG-IP system can send IPFIX log messages.|
|Destination||Create a log destination to format the logs in IPFIX templates, and forward the logs to the local-syslog database.|
|Publisher||Create a log publisher to send logs to a set of specified log destinations.|
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.
A log destination of the IPFIX type specifies that log messages are sent to a pool of IPFIX collectors.
The log destination periodically retransmits all of its IPFIX templates. The retransmissions are helpful for UDP connections, which are lossy, and they are also helpful for debugging a TCP connection.
Now you have an implementation in which the BIG-IP® system logs messages about DNS DoS events and sends the log messages to a pool of IPFIX collectors.
