FastNetMon port mirror configuration

In this mode you need to configure port mirror / SPAN / TAP from your switch or router device. We suggest using separate interface for management connection with FastNetMon for reliability reasons.

Enable plugin for mirror capture:

List all available interfaces for your system:

Enable capture for specific port (you may specify any number of ports):

Apply changes:

Then enable port mirroring on router or switch side.

If you have any performance issues with this capture mode, we suggest testing new experimental capture plugin: AF_XDP.
