Oh my god these port densities and values are great, why cant you just let me use fabric extenders without a switch? I would like to collapse my topography. Why is sfp28 breakout not supported on 5502, really strange because sfp+ breakout is supported, this was quite the bummer when noticed. What happens to qsfp connections if not all four channels are functional at the layer 1? Will it totally refuse to work or will it operate with degraded performance? I have had troubles getting a QSA (sfp+) to work on my 5502, the spec sheets and compatibility matrixes say it should work but I still cant get the things to work, I really hate the ideas of installing an extra switch just to get my links over 40km and under 80km running. Also why the heck is this stuff rated in KM and not db? The db/km loss on different fiber can vary quite significantly. 34:20 Let's see if I'm just screaming in the wind here.
Why cant you just let me use fabric extenders without a switch? This is because the fabric extender (FEX) does not have the hardware needed to handle routing or switching. The FEX is is a "dumb box" in that it has to send all of the packets to the parent switch to be handled. Even when traffic goes from one port on the FEX to another port on the same FEX it has to be sent to the parent switch to be processed and then is sent back to the FEX.

@@fashion_nugget273 Why can't the router do that? Why do I need a switch if I have extra capacity in my router?
