Agreed, but a functional and pretty door-stop at that. :-)

We recently had to introduce some temporary[0] ugliness consisting in
one end of a plain 2801[1] terminating traffic in a GRE tunnel. We could
pull 90 Mbps (max MTU) without it breaking a sweat. It was doing nothing
else of course.

For this purpose -- servicing a sub-linerate Ethernet circuit -- a
switch would IMO be a terrible choice. With a 2801 you can shape the
interface to 20 Mbps and use LLQ inside this shaper. The 3560 can do
nothing of the sort.


[0]: Normally (for us) the denomination "temporary" means a badly
     implemented but almost permanent solution. This one was actually
     temporary. :-)

[1]: Plain 2801 w/ 128MB RAM running 12.4(24)T4 Enterprise Base
