How do I get a DS10's onboard NIC into 100 mbps mode?

by hvlems＠zonnet.nl

Thanks Mark, very kind of you. A "good" switch is not necessarily one that is manageable. For sheer throughput I'd prefer a Cisco (a real one, not the SOHO stuff) or, better in terms of price performance, an HP enterprise class switch. Ebay often has interesting offers. The problem is cost of shipping. These switches are built for computerrooms, so the frame must support itself in a rack (and whatever is put on top of it) and the power supplies are usually built in and heavy. I prefer 100 Mb/s FD gear from HP and Cisco over a cheap 1 Gb/s switch. Sustained bandwidth for the latter may be worse!

Generally, coax links are always half duplex and UTP ports tend to be full duplex. There is very little 10 Mb/s equipment that supports full duplex though. Auto sensing tends to err on the safe side and your system ends up at 10 or 100 Mb/s half duplex. Auto negotiating mode will result in an appropriate setting, 100 Mb/s or 1 Gb/s full duplex. Old ethernet equipment, 10BASExxx gear won't do this at all. You're lucky if you can select between AUI and thinwire coax, sometimes UTP is offered. The second question depends on the quality of the switch. If a switch receives data at 10 Mb/s and transmits them over a 1000 Mb/s link then it depends on the design on how well this speed difference is handled and the way it is hidden for the other ports. If the switch has very little own memory, it must forward each packet as quickly as possible. In the mean time all other ports may receive less attention. Store and forward may be a better strategy to handle these differences in linkspeeds. The cheaper the switch is, it will probably offer just one strategy andd usually this works best in homogeneous networks (everything operates at the same bitrate and duplex mode). A cheap switch offers about the same throughput volume as an old fashioned repeater: then traffic between any set of two ports and all other traffic gets backed up at the systems. Is this an answer to your question?

Yes, I can confirm this - I recently install a DA500 network card in an AlphaServer 300 and I had to explicitly set fastfd mode on the network card device at the SRM console to get it to work at full speed once booted into VMS.
