VMware ESXi 5.x servers do not assign the PCI slot for each NIC in the same order as the NIC is added to the VM. As such, BIG-IP VE brings up the NICs in the wrong order and network traffic goes through the wrong NICs.


The network traffic goes through the wrong NICs. The management port might stop working and BIG-IP VE cannot get configured.


This happens when adding NICs to BIG-IP VE in VMware ESXi 5.x servers.


Do not assign more than 4 virtual NICs before the first boot on VMware, or manually change each NICs PCI slot number.
