That depends. For a test network, a VLAN-capable Layer3 switch can be quite
a nice tool, because you can partition the switch into 2 or 3 separate
virtual networks without buying a bunch of boxes.
I write this not because I think VLAN switches are a general necessity, but
rather because I have an idea of the kinds of activities Marc gets involved
in, and suspect his networking needs are often far beyond ordinary.
I'm going to add a testimonial for the HP switches here. Given that I'm a
former Xylan/Alcatel employee, this should carry some weight. The Alcatel
architecture is fairly good, but it carries a lot of baggage from the Xylan
"any to any" switching architecture which tends to drive their cost up a
bit. The HP ProCurves perform well and are reliable and (relatively)
cheap.
