Fairly straightforward question. The ISP-side port keeps shutting off, and they suspect it's due to spanning tree protocol. I have located on these forums that typing "brctl stp br0 0" on some sort of command line would disable it, but I just don't know how to use the command line. Probably so simple most people wouldn't even bother asking about it, but I'm no network administrator and I don't want to wade through a strange world for many days. Any help would be greatly appreciated.
