Someone could explain me that problem could have, if I have the following situation:
A dhcp Server, ACS Server, and various switches 3750 interconnected. But a hosts in the network has assigned statically one of the directions that the dhcp Server can assign to the computers.
Rank of IP to assign for dhcp Server: 172.23.8.1 172.23.8.100
Ip static of the host of network: 172.23.8.17
The ip 172.23.8.17 not this excluded in the dhcp Server.
