what kind of Cisco? We used to have a problem with an older 8-port 
Gigabit Cisco Catalyst, 3xxx (which we really just used as a converter 
from SX to LX) that would not, ever, push more than ~600 Mbps even 
though it claimed "10 Gbit Backplane" and we were only using two ports.

We finally figured it out applying cisco math:

"10 Gbit Backplane" = 5 Gbit full-duplex divided by 8 ports = 625 Mbit 
per Port per direction.

Kind regards,

Felix
