Last Modified: May 29, 2024

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

Known Affected Versions:,, 14.1.5,,,,,

Opened: Jun 15, 2023

Severity: 3-Major


The bigip.conf file differs before and after blade replacement


The bigip.conf does not list all the signatures added in the IM which is active


It happens when one of the blades is replaced


1) Try the command "tmsh save sys config" 2) If step 1 does not resolve the issue then try reloading the IM (Move to Factory Defaults IM and load the IM again). Then the bigip.conf will be updated with all the signatures supported by that IM)
