Hi;

STH has posted a Youtube video presenting the Mikrotik CRS354-48G-4S+2Q+. I thought "Hey, great product - let's buy a bunch of these!".

Problem: There are two of these switches, linked together either via a QSFP+ DAC Cable (Microtik Q+DA0001) or via QSFP+ fiber modules and cables. It should not matter if I use a DAC cable or fibler cable and QSFP+ modules, right?

The QSFP+ interfaces show up as four separate 10G interfaces qsfpplus1-1 through qsfpplus1-4 and qsfpplus2-1 through qsfpplus2-4.

How do I bundle these 4 links together in order to tell the switch that it should make a single 40G connection to its brother, and how do I do it so the switch hardware gets used and not the cpu (which is not that powerful)? Is bonding the right way?
