I'm using a SFE2000 with PoE with Asterisk.  Besides * and my management box
(MySQL, ARI, Queuemetrics, etc.), I have the 10 desk phones that I need PoE
for plugged into it, a mix of GXP2000, Linksys SPA941 and a couple of Aastra
480i and 9133i units.  One of the things that sold me on it was that it can
do 185W across all ports; you're not stuck giving 7W or 15W to each port
(which was a problem with many models I looked at and limits you to only 12
of 24 ports getting power).  I'm told the Grandsteams pull about 4W, and
since that's the phone with the widest deployment, I expect to be able to
drive 24 per switch eventually.

So far I've had no problems with it, though I'm not using it's layer 3
functionality.  I trunk two VLANs to a Baystack layer 3 switch, which was
pretty simple to set up and has worked properly ever since.  My setup
doesn't have both tagged and untagged packets coming into the same port, so
I can't speak to that.  The configuration certainly seems to support it, and
I suspect that the default "admit all / no ingress filter" combined with the
fact that every port has to have a PVID assigned means that it would work
pretty much out of the box after you configure your VLAN numbers.

The UI interface needs some improvement.  It's not quite sure if it's a
linksys or a cisco right now.  You can make all the configuration via a Web
GUI as you would with a typical Linksys SOHO router, but if you don't go to
"Admin -> File Management -> Copy Files" and choose to copy "running-config"
to "startup-config" (using drop-down boxes, naturally), it loses all your
changes on reboot.  :)

If you have other questions, feel free to contact me off-list.
