I've just ordered a D-Link DGS-1100 series low-end managed switch and

The DGS-1200 series supports LACP, but the 1100 only supports an
undefined
"static trunk aggregation" method.
DGS-1100 definitely does not support active LACP negotiation. The
"static trunk aggregation" it talks about is, basically, static
bonding, or what was once called EtherChannel. Which is exactly what
the trunk(4) manpage refers to as "IEEE 802.3ad static link
aggregation". You're good to go.
Yep. Between you and Stuart I'm pretty comfy now. I'm still hopeful
that they ran out of "Hardware Rev. A" and are shipping the "B" units,
which do LACP and STP. But that hardware may not be available here in
the U.S., I'd obtained the manual for the "B" variant from D-Link
Canada.
A related question is whether there even is such a thing as "IEEE
802.3ad static link aggregation", since the whole point of 802.3ad is
to define the link aggregation protocol (i.e. "LACP"). I don't have a
copy of the standard on hand to verify my recollection, though. (And
I'm not going to pay that much just for this, sorry.)
Me either. :( It's significantly more expensive than the switch.
Also, note that 802.3ad was renumbered, effectively, to 802.1AX-2008
which has since been superceded by 802.1AX-2014... not that anyone
really knows or cares about that level of detail.
When trying to figure out what "802.3ad static link aggregation" was,
I'd stumbled across this change in nomenclature.
Thanks for the help!
