Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP APM(all modules)

Known Affected Versions:
11.5.1, 11.5.2, 11.5.3, 11.5.4, 11.5.5, 11.5.6, 11.5.7, 11.5.8, 11.5.9, 11.5.10

Opened: Mar 31, 2015

Severity: 1-Blocking


On the 5000 and 7000-series platforms, APM standalone licenses potentially do not provide the needed license information for usage of the FastL4 feature. Upon attempts to use the profile, the user will be presented with the following error. 01020036:3: The requested profile (/Common/fastL4) was not found.


Creation and usage of a FastL4 profile will be prohibited by TMOS. Configuration using FastL4 will fail to load.


1. The only module listed as licensed in /config/bigip.license is 'mod_apm' 2. The platform is in the 5000 or 7000 series. 3. The feature ltm_proxy_fastl4 does not appear in 'tmsh show sys license detail'.


Renew the current license using any of the available commands, such as 'tmsh install sys license'. This will retrieve an updated license file from F5 which contains the needed licensing data.
