No pure switching. When I compare to FS switches they quote similar spec’s in terms of kpps and switching capacity so I began to wonder whether they are quoting L1 of L2. I always assumed L2 as we are talking switches here.
L2 comes with its own overhead (ethernet frame headers and whatnot) and inter-frame gaps … which take up relatively larger proportion of total capacity with smaller frame sizes (payload) compared to using larger frame sizes.
