See KB33477, if the "spare" capacity was there to boost the available pps budget for the artificially limited number of ports I don't think there would be any KB33477. Maybe some other architectural challenge, don't know?
Also this could be asked of any platform from any vendor, just give us 48x 40/100GE ports for each NPU and we'll figure out what to do with those. Maybe there will be use-cases where I enable all of them as I don't expect much traffic/pps to be generated on each port and maybe there will be cases where I enable just one port as I expect 64b frames @ line-rate and have 100k lines in the filter matching for packet size. You actually reminded me of the A9K-24X10GE vs A9K-36X10GE (yes please, I'll have 36 ports variant and I'll decide what to do with them). adam
