IP address Information available with DHCP snooping?

All,

Had a question I wanted to bounce off the group. Let's say I have a switch that is a DHCP server, but also has DHCP snooping enabled. All the ports are untrusted. IP source guard and Dynamic ARP inspection is configured on all interfaces as well. In addition to that, all ports are untrusted. When I have hosts connected to the switch, they pull an IP address from my DHCP pool, and everything is fine in the world.

Now, to get to what I'm "trying" to accomplish. I want to know if it is possible to do the following: A user with a static IP address connects to the switch in question. The switch takes note of the IP address and the MAC address configured on the static host, before denying the user on the network. Then, using that information, configure an EEM script to take that information and configure that interface with a STATIC BINDING and set the interface to TRUSTED. Once the host is removed, the configuration would revert to its previous configuration.

Any chance of this? Or am I just wasting my time?

Regards,
Dietrich
