How to implement Port security using Linux and Cisco Switch...?

I am trying to implement port security feature using linux and Cisco switch.I am very new to linux. I have a design which looks like this:

user-- switch---Linuxbox-----> database

So when an un knower user plugs into the switch port , the switch will send an SNMP trap to Linux router or Firewall. It will query with data base and sends back to switch and let the switch takes decision to allow or block. How will Linux box communicate with Cisco switch. Please let me know if i have to change my design.
Also How will a code written on Linux makes effect on to Cisco switch?

currently the swicth is trunked to Core.

This may help...

Key words when searching would be

NAC - Cisco Network Access Control)
802.1x - Port level Security

can't say any of that will be a straight guide, but it may help steer you in the proper direction.
