Is the Apple family of smart devices for example, DHCP fingerprints cannot distinguish To rely on any other fingerprinting information.įingerprinting alone cannot fully classify a device. These devices into their appropriate category, OS family, and name without having The information collected is definitive, ClearPass Profile can directly classify Then posts this information to the ClearPass Profile. Information from all devices during the onboarding process. ClearPass Onboard CollectorĬlearPass Onboard collects authentic device Supported versions are NetFlow v5 through v9 and IPFIX (Internet Protocol Flow Information eXport). The ClearPass Policy Manager NetFlow Collector provides the ability to identify the open ports of a device connected to a network by analyzing the received NetFlow packets. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination of traffic, class of service, and the causes of congestion. NetFlow provides the ability to collect IP network traffic as it enters or exits an interface.
You can configure multiple ip helper-address statements to send DHCP packets to servers other than the DHCP In addition to fingerprints, DHCP also provides the host nameĪruba controller and Cisco switch to send DHCP traffic to the ClearPass server, enter the following CLI commands: TheseĭHCP packets are decoded by ClearPass Policy Manager to arrive at the appropriate device category, You can configure switches and controllers to forwardĭHCP Discover, Request, and Inform packets to ClearPass. Most devices that use the DHCP mechanism to acquire an IP address List from the Discover and Request packets can uniquely fingerprint Option 55 (parameter request list), option 60 (vendor class), and the options
