ethernet switch and spi

I am using spi, a program to load register values into an
ethernet switch, to do things like
setting a vlan etc.
 
there is a particular command on spi called ddtab
which shows the dynamic address table.
that shows the mac address of any machine connected on the ports of the switch.

what i want to know is if it is possible to retrieve the
ip addresses (rather than mac addresses) --i mean
at this level, not at programming level, wherein, a tcp packet can be checked and all tht.

this is because there is an embedded controller that
would be used ultimately to program this switch , and what i want it to do is to use a legal list of ip addresses
that only should connect to the NW and nothing else.
mac addresses, is not a good way, i beleive

You would need a layer 3 switch to accomplish this.  If you have a layer 2 only switch you would need to add a router to your network and handle security at the router.
