4500 line card max throughput?

We are looking into upgrading our 4006/Sup3 core switches with 4506/Sup4 but are concerned with its switching fabric limitations as opposed to HP's comparable offerings (5406zl or the new 8200).


A Cisco CCIE told me that there is a 6GB limit per line card.


We are running a collapsed dual core with six 3550s and five 3524s on the edge.


We are concerned with this because this could be a potential bottleneck for us for the next 5 or 6 years.


Can someone shed more light or provide some good documents on this?


Thanks,

Thanks. But the doc doesn't say anything about the 6GB bottleneck to the switching fabric.


You confirmed what the Cisco employee said.


Never mind the "non-blocking" and "wire speed" beautification in the presentations abd ads. The only non-blocking ports are those in the Sup engines and certain ports in certain line cards.


I don't think I want to have our next 5-7 years depend on a platform like that.
