We are using a Cisco 3560 Switch as a DHCP Server. I understand how to set up multiple DHCP pools within the same network using Sub-netting. The issue is i would like to be able to assign on a per port basis of what DHCP pool to use.
For Example if i have 3 DHCP pools configured. I need FE0/1 to be asigned an address from DHCP pool 1 \ FE0/2 needs to be assigned an address from DHCP Pool 2 and the rest of the interfaces need o be assigned a DHCP address from DHCP pool 3.
Is there anyway to do this?

Create a Vlan for each subnet, then assign the interfaces to the specific Vlan you want them to be part off.

This does not help me, its the same question, I am not talking baout VLANs, i am talking abut DHCP Pools

The only way to break a broadcast domain for DHCP, it's through Vlan's, or routed ports. In your case you want to apply a different DHCP pools based on switchports; the way to do this is through VLAN assignment on the ports, and creating an SVI for layer 3 routing. The SVI will serve as the default gateway.
The DHCP pools will be distributed based on the broadcast segment you have assign them too.
I have taken the time to create a sample configuration on one of my 3560.

SVI = ?
Sorry for my ignorance - To many acronyms in the world today

SVI = Switch Virtual Interface, you are basically assigning an interface for each VLAN, for inter-vlan routing.
In the case of the example that I've posted, these are the SVI's:
interface Vlan1
ip address 192.168.1.1 255.255.255.0
!
interface Vlan10
ip address 192.168.10.1 255.255.255.0
!
interface Vlan20
ip address 192.168.20.1 255.255.255.0
!
interface Vlan30
ip address 192.168.30.1 255.255.255.0
