How are the ports that are on the supervisor module hooked into the fabric/PFC? Are they at any significant advantage or disadvantage compared to ports on linecards?
I'm primarily wondering because I'm wondering about the performance of sup32s. I understand that any linecard is going to be running on classic-bus with a sup32, and that probably adds a couple usec of latency vs fabric-switched packets. And I've seen various documents on how the various linecards are architected. But I've never seen anything describing how the onboard ports are dealt with. Are they operating as if they're on a fabric-connected linecard? Are their controllers directly hooked into the PFC? Or are they abortions just stuck on there for the sake of argument? I have various use cases where a pair of sup-32s in a 6503 chassis makes plenty of sense for what I need. I have a couple, and they're ok so far - but I have yet to really stress them out at all either.
