AWS - BIGIP HA is not setting IP on interfaces when on failover

Hi, I'm trying to deploy an high availability system on EC2, but when I've tested the failover actions, the BIG-IP pair are facing issue when trying to change the float IP adressess on AWS interfaces:

IAM Policy:

     "Version": "2012-10-17",
     "Statement": [
             "Effect": "Allow",
             "Action": [
             "Resource": "*"

Jul 28 11:02:21 ip-10-0-0-45 err logger: /usr/libexec/aws/ (traffic-group-1): Failed to reassign some or all address(es): on interface eni-8de3add1

Deployment guide I've followed:

Any idea?

Thank you in advance.

  • I have solved it. After debugging the "/usr/libexec/aws/" script file, I realize that looks like virtual servers can't have same ip address as float ip address. I changed it and all becomes to work.

      Hola junior, quería consultarte algo, publicar los servidores virtuales, ¿lo asociaste con una IP elástica?

        No recuerdo, pero probablemente fue solo con una IP de red privada fija.
