Sure, I'll grab one and send it across later this afternoon. Also, this isn't high priority -- I'm just going to disable LLDP on the ProCurve. Glen Martin Casado wrote: > Looks like there is a bug in the LLDP protocol handling. I can take a > look at this. Glen, would it be possible for yo

Hi all, We plugged an HP ProCurve switch into an OpenFlow switch today and it caused crashes in discovery: 2|pyrt|ERR:unable to invoke a Python event handler: Traceback (most recent call last): File "./nox/lib/util.py", line 115, in f event.total_len, buffer_id, packet) File "./nox/ap
