A while ago, there was a discussion on here about the differences in architecture between the various WS-X6x48-GE-TX modules and the resulting maximum throughput of those cards. Unfortunately, although I meant to keep a copy I appear to have deleted it and I can't find a reference on www.cisco.com.

So, can anyone confirm/deny my recollection that the WS-X6148-GE-TX and WS-X6548-GE-TX are both limited to 6Gb/s (6 groups of 8 ports, each on an ASIC with a 1Gb/s connection to the backplane) and the WS-X6748-GE-TX is required for full line-rate on all ports? (This is with a Sup720, no other daughter cards etc)

(I assume the architecture is similar within a card "family", so the WS-X6516A-GBIC will have the same total throughput as a WS-X6548-GE-TX)

Thanks.

I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time
