StackWise Plus performance

Hi
I found in documentation that StackWise Plus is providing up to 64
Gbps of throughput.
But is it full-duplex (then 128 Gbps half-duplex) or half-duplex (then
32Gbps full-duplex) ?
Is it per one port ? Or both stack ports ?

Rob

64 gigs half duplex, and that requires using the two stacking ports. For
more information, see:

just wondering why your company blocks access to google? ;-)

cisco provide plenty of white papers about its technology eg
