An end-user who has the technical savvy to give his or her station a valid IP
address can circumvent DHCP quarantining. This is one reason that 802.1X is
the recommended option for high security.
DHCP Plug-in Deployment.
When the NAC 800 boots, it tries to connect to
the DHCP servers you have defined for the DHCP plug-in deployment. If the
NAC 800 cannot communicate with a particular DHCP server, it will continue
to try to contact that server at regular intervals—not stopping until it either
reaches the DHCP server or you remove that DHCP server’s information from
the NAC 800’s configuration settings.
If a DHCP server cannot communicate with the NAC 800, the DHCP server
activates the failover parameters that you have configured. It either allows all
traffic or denies all traffic.
To enable the DHCP plug-in deployment method, you must install the Device
Activity Capture (DAC) utility on the Windows DHCP server. Because the
utility is installed on a remote device, it is referred to as the remote
DAC(RDAC) utility. The RDAC utility listens for DHCP traffic and sends
DHCP-related information to the NAC 800.
