Don't confuse *having* FE/GE ports with driving them at line-rate ;)
I have a great many Cisco routers here with FE port(s) on that are utterly
incapable of passing even 10Mb of traffic - regardless of whether it's on
ethernet ports or some form of WAN interface...
I haven't yet done any testing (or even looked at the paper numbers in any
depth) for the ISRs, although I understand things are getting much better.
Regards,
Tim.
