Torching a specific port on a MikroTik switch or router running RouterOS

Posted by jpluimers on 2023/04/11

On most recent [Wayback/Archive] RouterOS configurations of MikroTik Routers and Switches, running [Wayback/Archive] Torch a port will show zero traffic when they are part of a bridge configuration. The same holds for the Packet Sniffer.

The reason is that these bridges have hardware acceleration turned on, which makes all traffic go through the switch chip instead of the device CPU. Torch works on the CPU level, so won’t show hardly any traffic except for some configuration stuff (depending on the combination of switch chip and CPU type).

This is not documented in the Torch documentation, but it is documented in the Packet Sniffer documentation.
