Explanation: From the debug output, we see the following key information:
send_vip_arp: vd root master 1 intf port1 ip 10.0.0.13
send_vip_arp: vd root master 1 intf port2 ip 10.0.1.13
This shows that the IP address 10.0.0.13 belongs to port1 on the primary FortiGate. The logs also indicate that the Elastic IP was associated with the ENI (Elastic Network Interface) holding the address 10.0.0.13. Since 10.0.0.13 is tied to port1, the Elastic IP is effectively associated with port1.
The logs mention moving the secondary IP and associating the Elastic IP to the interface where 10.0.0.13 resides, confirming that port1 is the interface with the Elastic IP.
Therefore, the correct statement about the debug output is that the Elastic IP is associated with port1 of the (now active) FortiGate unit.
