[c-nsp] 7301 - copper vs fibre port throughput

[Tom Storey]

Hi all.

Been watching a thread on a forum where someone using a 7301 was
suffering rather lousey speeds through a 7301 when using an onboard
copper port between him and his ISP - only able to obtain about 25mbit
or so of throughput (all traffic NATed.)

After moving the ISP link over to fibre, the throughput shot up to
500-600mbit (NATed.)

Theres not much room for playing around with the setup at this stage,
but does anyone have any ideas why this might be so?

The onboard ports are all gigabit as far as I know, whether or not you
use copper or fibre, and the copper port augo negotiated at 100/full
with the remote device so I cant think of a reason for the disparity.

Thanks
Tom
