- <para>A boolean. When true, enables LLDP link receive support.
+ <para>Controls support for LLDP reception. Accepts a boolean or the special value
+ <literal>routers-only</literal>. When true, incoming LLDP packets are accepted and a database of all LLDP
+ neighbors maintained. If <literal>routers-only</literal> is set only LLDP data of various types of routers
+ is collected and LLDP data about other types of devices ignored (such as stations, telephones and
+ others). If false, LLDP reception is disabled. Defaults to <literal>false</literal>. Use
+ <citerefentry><refentrytitle>networkctl</refentrytitle><manvolnum>1</manvolnum></citerefentry> to query the
+ collected neighbor data.
