I used 'fastfd' as was hinted at in the <document found via random google hit> I was looking at at the time. On this subject, if you don't mind me asking, am I right in thinking that the speed that is setup for the network connection exists solely between the machine and the switch? I was experiencing some weird behaviour the other day that suggested otherwise. I have my work machine and a VAXstation 4000/VLC connected to a gigabit switch, which is in turn wired down to another gigabit switch in the basement. The VAXstation is a diskless satellite node off an AlphaServer 1000A. (I can feel an ascii art diagram coming on) Attic VAXstation O O Work Sunray + VPN Router 10MB | | 100MB ------ | | GB switch ______ | | 1GB link ~ ~ ------ | | GB switch ------ 100MB | | 100MB AlphaServer 100A O O Vigor ADSL Router ~ * big, wide world So why, if I a have a terminal on the VAXstation scrolling at high speed do I see my work machine (which is connected to the internet) significantly slow down? It looks to me like the whole link between the two GB switches is being dragged down to 10MB. Would the 10MB link working at half-duplex make any difference to the question? Thanks for the help, Mark. On Wed, 28 Sep 2011, hvlems at zonnet.nl wrote: Fast translates as 100 Mb/s half duplex and you wouldn't want that. Auto is not always sufficient. There are two auto modes, auto negotiate and auto sensing. IMHO the latter is better avoided. ------Origineel bericht------ Van: Oleg Safiullin Afzender: owner-hecnet at Update.UU.SE Aan: hecnet at Update.UU.SE Beantwoorden: hecnet at Update.UU.SE Onderwerp: Re: [HECnet] How do I get a DS10's onboard NIC into 100 mbps mode?
