Virtual LAN Sample Application

Overview

|
********
|
|
|
|
|
|
|
|
|
|
The VLAN sample application for Zephyr will setup two virtual LAN networks.
|
|
|
|
|
The application sample enables net-shell and allows users to view VLAN settings.
|
|
|
|
|
|
|
|
|
|
The source code for this sample application can be found at:

|
:zephyr_file:`samples/net/vlan`.

Building and Running
|
|
|
|
|
********************
|
|
|
|
|
|
|
|
|
|
A good way to run this VLAN application is with QEMU as described in
|
2019-03-08 01:23:10 +08:00
|
|
|
:ref:`networking_with_eth_qemu`. You can use *zeth-vlan.conf* configuration
|
|
|
|
|
file when running *net-setup.sh* script in Linux like this:
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
|
|
./net-setup.sh -c zeth-vlan.conf
|
|
|
|
|
|
|
|
|
|
Note that VLAN is only supported for boards that have an ethernet port or
|
|
|
|
|
that support USB networking.
|

|
|
|
|
|
|
|
|
Follow these steps to build the VLAN sample application:
|
|
|
|
|
|
|
|
|
|
.. zephyr-app-commands::
|
|
|
|
|
:zephyr-app: samples/net/vlan
|
|
|
|
|
:board: <board to use>
|
|
|
|
|
:conf: prj.conf
|
|
|
|
|
:goals: build
|
|
|
|
|
:compact:
|
|
|
|
|
|
|
|
|
|
The default configuration file prj.conf creates two virtual LAN networks
|
|
|
|
|
with these settings:
|
|
|
|
|
|
|
|
|
|
- VLAN tag 100: IPv4 198.51.100.1 and IPv6 2001:db8:100::1
|
|
|
|
|
- VLAN tag 200: IPv4 203.0.113.1 and IPv6 2001:db8:200::1
|
|
|
|
|
|
|
|
|
|
Setting up Linux Host
|
|
|
|
|
=====================
|
|
|
|

|
2019-03-08 01:23:10 +08:00
|
|
|
The :zephyr_file:`samples/net/vlan/vlan-setup-linux.sh` provides a script that
|
|
|
|
|
can be executed on the Linux host. It creates two VLAN interfaces *vlan.100*
|
|
|
|
|
and *vlan.200* on the Linux host and creates routes to Zephyr.
|
2018-01-16 22:54:30 +08:00
|
|
|
|
|
|
|
|
If everything is configured correctly, you will be able to successfully execute
|
|
|
|
|
the following commands on the Linux host.
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
|
|
ping -c 1 2001:db8:100::1
|
|
|
|
|
ping -c 1 198.51.100.1
|
|
|
|
|
ping -c 1 2001:db8:200::1
|
|
|
|
|
ping -c 1 203.0.113.1
|
2019-03-08 01:23:10 +08:00
|
|
|
|
|
|
|
|
The network packets to *2001:db8:100::1* or *198.51.100.1* will have VLAN
|
|
|
|
|
tag 100 set to them. The vlan tag 200 will be set to network packets to
|
|
|
|
|
*2001:db8:200::1* or *203.0.113.1*.
