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?
