JP; I've had this very issue. I know that 2.6.24-16 allows PVST BPDUs to cross the bridge. Linux won't speak Cisco PVST+ but it will pass the BPDU's so that Cisco devices on both sides can communicate about the link state. That has been my experience anyway (long and painful I might add).

I tried contacting both Gergely Madarasz (the author of the patch) and Ian Schwimmer (who started the thread) without any luck. Does anyone has this patch? Or, for that matter, a solution on how to do this? I'm currently using ebtables on SLES10SP2 to DROP the switch's BPDUs, avoiding it from shutting down the port; I have also changed the bridge's ULA in order to use "per-vlan" STP. This situation if far from ideal, of course: it would be great to have STP working between the Linux box and the Cisco switch (or any other switch), allowing it [the Linux Box] to "fail-to-wire" if something was to go wrong.
