Hello,
we are running 08040a.

The Brocade manual says:
> In release 8.0.30, the breakout support on the 40G interfaces will be supported on a standalone mode only. Breakout ports will not be supported with stacking configuration.

But this was just a side note as we did not expect such a limitation and 
were suprised when we discovered that information in the manual.

Is there any difference on the switch side if there is a breakout cacble 
connected? Is there such a thing like hardware support for breakout cables?

Until now, I was under the impression that a 40G port is just an 
aggregated 4x10G port and the switch just needs to deactivate the 
aggregation in order to break out? Am I wrong?
