BIG-IQ Web App Security (ASM)
Known Affected Versions:
5.4.0, 5.4.0 HF1, 5.4.0 HF2
Opened: Mar 20, 2018
ASM import fails after upgrade due to hostnames. The restjavad.0.log file displays a messages similar to: 'Failed POST to target https://localhost/mgmt/cm/asm/working-config/policies/<id>/host-names: java.lang.IllegalArgumentException: Duplicate item'
ASM configuration import fails.
The issue happens when host-names are configured and upgrade was performed from a version before 5.4.
On BIG-IQ, All existing host-names inside a policy must be deleted and recreated either manually or by importing BIG-IP(s) configuration (easier).
This issue no longer occurs.
