I'm not a programmer, so please excuse me if this should be obvious. I was
able to get IBsim running with the topology from our IB fabric loaded, I've
got opensm running against IBsim and doing things like ibtracert gives back
the exact results as we get on our IB fabric.

When trying to do commands in IBsim like clear to reset the links for a
node, I can't find the correct nodeid vaule to pass in. Here is a dump and
what I've tried.

If there is some documentation available for IBsim? I was not able to find
it through searching on Google. I am also interested in setting up a fifo
so that I can use a script to pass in fabric changes, then run some
commands, make fabric changes, run commands, rinse and repeat. I could use
some help/documentation for that as well.

Thanks,
