You can configure the BIG-IP system to send log messages about carrier grade network address translation (CGNAT) processes to the local Syslog database on the BIG-IP system.
When configuring local logging of CGNAT processes, it is helpful to understand the objects you need to create and why:
|Object to create in implementation||Reason|
|Destination (formatted/local)||Create a formatted log destination to format the logs in human-readable name/value pairs, and forward the logs to the local-syslog database.|
|Publisher (local-syslog)||Create a log publisher to send logs to the previously created destination that formats the logs in name/value pairs, and forwards the logs to the local Syslog database on the BIG-IP system.|
|LSN pool||Associate a large scale NAT (LSN) pool with a log publisher in order to log messages about the traffic handled by the pool.|
Perform these tasks to configure local logging of CGNAT processes on the BIG-IP® system.
Create a formatted logging destination to specify that log messages about CGNAT processes are sent to the local Syslog database in a format that displays name/value pairs in a human-readable format.
