Severity: 3-Major


Unable to use extra capacity after installing an APM add-on license with a larger session count.


Unable to use extra session capability; can use only the 10-session maximum provided by the APM Light license.


This occurs when the add-on License generated lacks the mod_apm license, meaning that no full APM license was previously installed, only the APM Light license (which constrains connections to a 10-session maximum). To determine whether this condition exists, check the bigip.license file, or execute the following command: tmsh show sys license details. If only mod_apml is present and session counts are higher than 10, then the system is in the condition that triggers the problem.


Contact your F5 sales representative to get the correct APM add-on license with mod_apm, as well as the additional session count capability.

Fix Information

The BIG-IP GUI now displays an error if an APM user count add-on license is used without a base APM license. The system reports such licenses as 'Licensed (Incomplete)'.
