Dear all

I would like to ask if FEX N2K module are working with

- non blocking mode or what called wire speed or not
- local switching within module ports

Hi,

The FEXs do not do local switching.  If you need to go from port 1 to port 2, the packet goes up to the parent switch and gets switched there from port 1 to port 2.
