Ok, fwiw, I have tried to make switch to switch variability less pronounced (in xCAT 1, you had to tell it what type of switch it was and sometimes what firmware version, etc etc, in xCAT 2 it auto detects and endeavors to tolerate a few different naming conventions as well as varying firmware conventions).
Of course, for certain scales any topology cue may be more effort than it's
worth and using nodediscorverls/nodediscoverdef type interface may be more
sensible. It's one reason why I'm hoping that we'll get out this year a
manager that can more seamlessly merge successful PXE boot environment, PXE
attempt, SLP, and other discovery schemes into a more friendly beast for
places where a human can sort it out about by hand or by some homegrown
special sauce. nodediscoverls does a serviceable job for successful pxe
boots, but there's a lot more 'discovery' schemes that can be employed.

Subject: Re: [xcat-user] Frustrating time with sequential node discovery
I can answer that point from a personal viewpoint - it's just a pain. A
real bad pain, especially when you do not have homogenous switch
models/vendors in the environment. By the time you've finally gotten it to
work you could have just went node to node and hand-written down the MAC's
and populated it yourself :-)
Typically when doing deployments now where xCAT is utilized I require the
vendor to provide me a list or spreadsheet of node-to-MAC mappings, and
just manually populate the tables myself with a for loop.
