RE: [EXTERNAL] bonding module not loading in Stretch

Can you share a full example of how it all works together?

Please disregard - it's been so long I forgot that files had to end in
".conf". Also assumed that "max_bonds" did something else.

Working quite nicely now! Three instances of the bonding driver and a pile
of VLANs load automatically on boot now.

Hi list,

This isn't ISP-specific but I know quite a few run this driver.

I'm attempting to roll a new router/firewall using Debian 9 and am hitting a
wall with the bonding module. The last time I configured bonding was on
Squeeze (Debian 6), I did through adding

	"alias bond0 bonding
	options bonding <whatever>"

into /etc/modprobe.d/aliases.conf, and adding some shortcuts in
/etc/network/interfaces to call ifenslave.

I see now that the preferred method is to do everything in the interfaces
file, by passing options like "bond_mode" and so on.

The issue I'm running into is that I can't get the bonding driver to load on
boot. After a fresh boot, "ifup" returns "no such device". I must manually
modprobe bonding in order to get it running. This happens despite adding the
above options into a file in /etc/modprobe.d. For similar reasons - or so I
assume - I can't get additional bonds to work unless I manipulate
/sys/class/net/bonding_masters as suggested here

It seems the real problem is that things I put into /etc/modules or a file
under /etc/modprobe.d are ignored.

Are things done differently now? I mostly missed Debian 8, it wouldn't
surprise me if I'm just ignorant.
