I'm feeling pretty happy with the Mikrotik CRS354-48P-4S+2Q+RM I got as my core switch.The web interface is a bit of a dumpster fire, but the command line is actually really slick.Tab completion, color, scriptable.Has enough ports that I can just patch everything in, ready to upgrade with 40G links, plenty of PoE, etc.Thanks to everyone who recommended I look at Mikrotik, I wouldn't have gone with this otherwise.
