Sending LTM\GTM logs to DCD devices

Hello all,

 

I am currently working on installing four DCD's to the F5 estate I manage and am looking to export the logs from the BIG-IP's to the four DCD's using an HSL setup to load balance these between these.

 

Reading through the following link Create a remote logging pool of DCDs (and others) it is clear that different modules require different port numbers to be used for logging but is there a specific port to be used for sending logs from the LTM and GTM modules? I see no reason why this wouldn't be possible but I can't find details anywhere that specify which port should be used for these.

 

Any pointers would be much appreciated.

 

Thanks

    Sending LTM/GTM syslog and audit logs directly to a standard BIG-IQ setup via High-Speed Logging (HSL) is not supported. BIG-IQ is designed to act as an event aggregator primarily for security and access events (e.g., ASM/AFM/APM). It is not built to function as a general syslog collector for standard LTM system logs.
