The other question is what is the actual capability of the GigaE cards in
a cisco box? I have been told (not played with GigaE on cisco yet and for
that matter, neither has the person who told me) that it is limited to
On a 7xxx Cisco, yes, it's limited to 400Mb/s, due to limitations on the
interface to the backplane (or VIP2 in the 75xx).
On the Cisco 12000, the backplane interface is 2.5Gb/s, so the GigE cards
can run at full speed.
Interestingly, no-one seems to have mentioned LINX yet in this discussion.
LINX have been offering GigE connections to their switch for over a year
now as a trial, and in the last few months they are now "live". There are
apparently some LINX members pushing a few 100Mb/s through their GigE
E.g. see http://stats.sjc.above.net/traffic/lhr/linx-1.html
