The order of interfaces in BIG-IP Virtual Edition (VE) is determined by the Linux kernel. The order of interfaces on BIG-IP systems tmm does not match the one determined by the Linux.
Sometimes the order between the two does not match. This makes it difficult to reliably use the order with automation to ensure the right devices belong to the correct VLANs, and other operations.
-- Repeatedly deploy BIG-IP configurations within KVM with many (e.g., 6 or more) interfaces. -- Observe the order of devices on the PCI bus and the order that they are enumerated within tmm (1.1, 1.2, 1.3, etc.).
Interrogate the MAC addresses of interfaces to map them against NIC definitions to determine the order.
There is now a predictable NIC ordering based on PCI coordinates until ordering is saved.
The NIC ordering is now based on PCI co-ordinates, so you no longer need to interrogate the MAC addresses of interfaces to map them against NIC definitions to determine the order.
