Last Modified: May 29, 2024

Known Affected Versions:

Opened: Mar 18, 2021

Severity: 3-Major


If swapping management and data plane NICs using the onboarding Terraform template, you will receive a, “License is not operational (expired or digital signature does not match contents)” message.


After swapping NICs and rebooting the instance, BIG-IP cannot successfully validate the PAYG license.


- A multi-NIC instance deployed in Azure or AWS using a PAYG license. - Use the onboarding Terraform template to swap the management (1st NIC) and the data plane NICs.


Due to Azure and AWS metadata service calls restricted to using the primary IP address, avoid swapping NICs, as it is currently NOT supported in those Clouds.
