Opened: May 06, 2020 Severity: 3-Major
The following error occurs when importing a BIG-IP SSM module onto a BIG-IQ system: "Failed to copy configuration to working-config; reason: Failed copying from source subcollections to target subcollections: %s: java.lang.IllegalArgumentException: The dynamic signature mitigation (manual-multiplier) must be [none, low, medium, high]."
You will not be able to import BIG-IP on BIG-IQ
This occurs when you are using DoS protection features and have set "Mitigation mode" to "Manual multiplier" under Security :: DoS Protection : Device Protection : Network Properties
To unblock import, modify the config files on BIG-IQ as follows: 1. Launch TMSH console on BIG-IQ and identify relevant .json files which contain the impacted property $grep "dynamicSignaturesMitigationValues" /var/config/rest/security/dos/* 2. Identify the files for the highest BIG-IP version supported by BIG-IQ. This is because these settings are not loaded from the json corresponding to the version of BIG-IP you are attempting to import. For example if step 1 reports *-16.1.x.json files as the highest version, then use those for the subsequent steps 3. Edit each file and add the entry "manual-multiplier" under property dynamicSignaturesMitigationValues as follows: "dynamicSignaturesMitigationValues": [ "none", "low", "medium", "high", "manual-multiplier" <================= ], 4. Restart restjavad service $bigstart restart restjavad 5. Re-import BIG-IP on BIG-IQ
None
