10The Link Layer Discovery Protocol sample application for Zephyr will enable
11LLDP support and setup VLANs if needed.

13The source code for this sample application can be found at:
14:zephyr_file:`samples/net/lldp`.

21Building and Running
22********************
23
24A good way to run this sample LLDP application is inside QEMU,
25as described in :ref:`networking_with_qemu` or with embedded device like
26FRDM-K64F. Note that LLDP is only supported for boards that have an ethernet
27port.

29Follow these steps to build the LLDP sample application:

38Setting up Linux Host
39=====================
40
41If you need VLAN support in your network, then the
42:zephyr_file:`samples/net/vlan/vlan-setup-linux.sh` provides a script that can be
43executed on the Linux host. It creates two VLANs on the Linux host and creates
44routes to Zephyr.
