100 mb Full duplex on fiber connection

[Guest]

I have a fiber link between 2 buildings (distance approx. 500 meters)
3com superstack II 3000 on one side and HP2424M on the other.
Problem is I can't get 100 mb half or full duplex to work properly.
Roadkil's Comtest (http://www.roadkil.net/) shows an 9000 kb/s out but
the bytes in's stays below 50?
I tried to set both sides manually of course, but I get the best
results by setting it to 10mb half duplex 468/1144.


Thing is that I need to copy a 6 GIG Oracle dump file nightly between
the two buildings and I need the speed


Anyone can shine a light on my prob?


Thanks in advance,


Mike

If you look at the snmp data on the switches on both sides, are you
seeing any errors?
