Interface addition - is this a bug?

be ESXi gives the new device a number less than an already existing.
Possibly there is a way to change it in ESXi.

That concerns to VLAN and FreeBSD 10.1. The TO didn't mention the use of VLANs.

Besides, that bug should be fixed long ago I think, isn't it?

@viragomann I don't know either!

it's not a bsd bug, it's an esxi thing ... it appears to still be relevant. the bug is indeed related to vlans, but the issue of the reordering is addressed aswell

esxi has been reordering interfaces after >4 Vnics of the same type, for as long as i can remember. that's one of the reasons i prefer to let the VM handle the vlans and not the host.

@viragomann I've actually got VLANs configured on one of the NICs from a previous network arrangement but i'm not using them.

It's just how ESXI probes NICs.

<4 is: 1,2,3,4
If you have 8, it becomes: 1,5,2,6,3,7,4,8

Check the MACs, reassign the networks and/or interfaces to match what you want in pfSense.

@jimp Can't you do something cleverer then? It was just blind luck that my LAN assignment was NIC1 otherwise i'd have lost access.

Not without a ton of work to try to make NICs persist or be matched by their original hardware address. Gets tricky fast. There is a feature request out there for that, but in practice it's a rare need.

On a regular (non VM) pfSense maching i'd hate Mac-mapped nics.
Would make "cloning" a config to a new machine "ugly"

@bingo600 I'm not advocating that as the only method, just a small table lookup for existing MAC addresses with a failover to the current way of working if not in the table. A clone would therefore work as before since none of the MAC addresses would exist.
