Many MikroTik devices come with built-in switch chips that usually have an option to do VLAN switching on a hardware level, this means that you can achieve wire-speed performance using VLANs if a proper configuration method is used. The configuration method changes across different models, this guide will focus on setting up a basic trunk/access port set up with a management port from the trunk port using different devices with the right configuration to achieve the best performance and to fully utilize the available hardware components.

For devices that have multiple switch chips (for example, RB2011, RB3011, RB1100), each switch chip is only able to switch VLAN traffic between ports that are on the same switch chip, VLAN filtering will not work on a hardware level between ports that are on different switch chips, this means you should not add all ports to a single bridge if you are intending to use VLAN filtering using the switch chip, VLANs between switch chips will not get filtered. You can connect a single cable between both switch chips to work around this hardware limitation, another option is to use Bridge use Bridge VLAN Filtering, but it disables hardware offloading (and lowers the total throughput). |
