Link Layer Discovery Protocol (LLDP)¶
The Link Layer Discovery Protocol sample application for Zephyr will enable LLDP support and setup VLANs if needed.
The source code for this sample application can be found at: samples/net/lldp.
Building and Running¶
A good way to run this sample LLDP application is inside QEMU, as described in Networking with QEMU or with embedded device like FRDM-K64F. Note that LLDP is only supported for boards that have an ethernet port.
Follow these steps to build the LLDP sample application:
west build -b <board to use> samples/net/lldp -- -DCONF_FILE=prj.conf
Setting up Linux Host¶
If you need VLAN support in your network, then the samples/net/vlan/vlan-setup-linux.sh provides a script that can be executed on the Linux host. It creates two VLANs on the Linux host and creates routes to Zephyr.
