<DIV></DIV>Hi there,<BR> As I noticed that the dhcpd only
gives out the IP address assigned to certain MAC address in the log file, is it
possible for the dhcp server gives out more detailed log information? If we can
get the option 82 information in the log file, it will be great and in fact
necessary for we need that information in case we need to trace the customer
from the log.<BR><BR>Best,<BR><BR>Wei Wei<BR><BR>
