    <fingerprint os="Example" os_class="Windows" os_url="https://www.extremenetworks.com" comments="Example Device Type" author="jsmith" lastmodified="2020-11-12-05:00">
    <tests>
    <test weight="5" matchtype="exact" dhcptype="Any" dhcpmacoui="Extreme Networks, Inc."/>
    <test weight="5" matchtype="exact" dhcptype="Any" dhcpmacoui="00-00-AB"/>
