Assigning static ip address via DHCP

[Kearle230]

I have a problem. I would like to assign static ip address via DHCP.

What I am trying to do that is working:

1. Config a static ip in switch to lookup PC mac-address.

2. The pc is set to DHCP

3. The pc is connected to the switch

4. The switch identifies the mac-address

5. Assigns the configured ip address DHCP to the assigned mac-address.

My problem is:

The switch is assigning ip address to pc automatically.

I do not what the switch to assign ip if the ip address has not been assign a mac address.

My question: How do I configure the switch to prevent DHCP from assigning ip address if the mac address has not been pre-configured with an assigned ip address?
