fluidsynth - show active router rules

Question

In fluidsynth we can set up routing MIDI signals. Say this way:

router_begin note
  router_chan 15   15  0    0  
router_end

But if the rule is incorrect it does not work or is not accepted. So I want to have an overview of currently working router rules.

I cannot find a command for fluidsynth, how to show/print out active router rules. Say something like:

router_show # it does not work

Do you have some idea how to display active routing rules in fluidsynth, which are currently applied on MIDI signals?

Is there any command that does show midi router rules in fluidsynth?
