Opened: Dec 18, 2017

Severity: 3-Major

Symptoms

The config is not loaded after upgrade

Impact

The config will not load after upgrade if the syntax is not valid in a new syslog-ng version.

Conditions

In v13.0.0, the syslog-ng version changed from 2.1.4 to 3.8.1. Syslog-ng include options may contain syntax which is correct in 2.1.4 syslog but is not correct in 3.8.1. TMOS does not parse the 'include' option, or translate it from older versions to newer, or any other modification. It blindly copies it into the configuration file.

Workaround

Manually modify the 'include' option in BIG-IP_base.conf file after upgrade. The config cannot be loaded so tmsh will not work.

Fix Information

None
