Symptoms

Protocol inspection in the security log profile is not activated/enabled when the first log profile has Protocol Inspection disabled and is already attached to the virtual server.

Impact

Inconsistency in configuration behavior.

Conditions

1. Create the first security log profile (for example, enable a sub-module other than Protocol Inspection) and attach to a virtual server (VS). 2. Create the second security log profile with Protocol Inspection enabled, select a publisher and attach to the VS. 3. Event logs are not sent through the selected publisher which is not expected. Therefore, the protocol inspection log profile attached later to the virtual server is not effective.

Workaround

Run the below command to detach the profiles from virtual server (VS) and attach the required log profile first. tmsh modify ltm virtual <VS Name> security-log-profiles none

Fix Information

None
