How do I enable VLAN tagging in Linux?

There are two steps required in order to use VLAN tagging on your Linux server:

  1. The first is to hook it up to a switch that has VLAN enabled, connected to a port which is allowed to act as a trunk.
  2. The second thing you’ll need is to create virtual interfaces assigned to the desired VLAN .

How do you test if a VLAN is working?

Use the show vlan command to verify your VLAN configuration. This command displays all switchports and their associated VLAN as well as the VLAN status and some extra parameters that relate to Token Ring and FDDI trunks. You can use the show vlan id [vlan#] command to see information about a particular VLAN.

How to configure tagged VLAN interface on Raspberry Pi?

The easiest way to configure tagged VLAN interfaces is by editing the file /etc/config/network. You can edit it through an SSH session into your Raspberry Pi, or by inserting the SD card into your computer. Here is what that file should look like:

What are the disadvantages of using a VLAN on Raspberry Pi?

The disadvantage is that all VLANs will have to share the bandwidth of one single network interface. Most modern managed Ethernet switches can handle VLAN tagging. All you need to do on the Switch side is enable tagging of the selected port to all the VLANs you want to connect to your RPi.

How to tag ports in Raspberry Pi firewall?

In the same screen, select VLAN Id “2”, click ports 1, 2, and 3 to be blank (not members of VLAN 2), click on port 4 to be “U” (untagged), and click on port 5 to show “T” (tagged). In summary, port 5 should be a member of both VLANs, and be tagged in both.

Why are all Ethernet ports untagged on Raspberry Pi?

Normally all Ethernet ports on a managed Switch are Untagged. This means that all packets sent and received by the Switch are unchanged. In this configuration each Ethernet port will carry the signals from one single VLAN only. A broadcast packet sent on e.g. VLAN 2 will only output from the Ethernet ports which are untagged to VLAN 2.
