It would be a layer 3 switch if he is using an ASIC for routing.  A L3
switch routes in hardware and a L3 router routes in software. 

To clarify, if your still cloudy, a switch can have only 1 management
Vlan.  It's the one with the virtual interface.  A switch can have
varying amounts of "data" vlans as well.  These are applied to ports and
do not have an explicit ip address.  Anywhere from 64 to 4096+ of them
can be supported depending on hardware and trunking methodology.  Your
management vlan can by 248 and your AP vlan can be 250 with no issues.
You will need to have a layer 3 device somewhere handle the inter-vlan
routing.
