Many thanks for all the advise so far. Shayne - will try your idea, sounds promising for a diagnosis step. Will revert on this.
Scott - pretty much all good there, under speed test the board sits at about 65% idle. FW uses about 10% and queues about 10%. Turning all rules and queues results in a minimal speed improvement (a couple of meg only). Sam - have played around a fair bit re auto, etc. On that interface, 10 and 100 with no auto negotiate come up fine but for some reason 1000 with no auto just stops the interface from coming up. Cycling through 10/100/100 with auto on and off and testing each one , the best result so far is 1000 with auto negotiate (can't test without because interface just stays down). I may swap out that cable tomorrow just to be safe and then recheck. Again, thanks for all the pointers.
