To see the upper/lower links to a bridge, you want to execute (as root):

ngctl ls -l

The output is a bit cluttered, as there's no empty newline between the head=
ers as it enumerates the different types.

Just as traditional "ls" you can give it a path, however the path is not de=
limited by "/" but by ":" to separate the peers, etc.

Start small by trying to ls your bridge (and then ls -l your bridge). If me=
mory serves (on the go, so don't have a terminal to try this out before giv=
ing the tip):

	ngctl ls -l bridge0:

Should perhaps show the connected links.

When in doubt=85 go interactive=85

	ngctl

And try different combinations of "ls" and "ls -l" on the prompt.
