Are we talking the support of FE interfaces, or support of FE throughputs ?
The switch may indeed support FE ports, but performance of the router will
vary with packet size, IOS featues etc. I would be very suspect of the 2621
supporting even 1x10baseT FD at wirespeed ...
Based upon my experience (limited I conceed) the 72xx is the minimum router
to support the potential throughput of multiple FE ports ...
Regards
Mike
