John, we are considering these nexus switches as a core for a small (for now) exchange point, so there will definitely be multiple ports talking to one and vice versa. Let's say the switch would be utilized up to 90% (45 ports in case of 5548, 90 in case of 5596), half of the active ports

Hi Jiri, These total numbers are not a problem, all ports are equal and all traffic goes to the fabric on every port. You will only see drops in this scenario if you have bursts of traffic going from many to one port for a period of time larger than the buffers will allow. Remember, the
