Okay, have just now replaced the 3c905B with a 3c905C - I'm still getting overruns:
Single highspeed download source - 100/minute. Multiple concurrent downloads - 600-700/minute
I'll try out an intel e100 card later, but I suspect the cards are all fine.
Okay, I'm now running with an Intel e100 card, and it's looking a lot better:
Single highspeed download source - 1-2 overruns per minute. (this source can drive the link at sustained 3.5-4Mbyte/s, peaks at up to 5-6Mbyte/s).
Multiple concurrent downloads - 4-5 overruns per minute.
I can probably live with this, but it's annoying.
TX or RX overruns?
Only RX overruns.
They're usually caused by duplexing errors, maybe due to incorrect auto-negotiation of link parameters, but can also be caused by faulty or out-of-spec cabling.
Have you properly tested your patch and/or structured cabling plant? I'm not talking about just continuity/wire-map testing, but properly testing to certified standards including cross-talk, insertion loss etc?
No, nothing like that. Haven't got the equipment for that.
Also, try locking down one or both ends of the network link to a fixed speed/duplex setting (e.g. both ends at 100Mb FD.
Yes, they're both at 100Mbit FD.
If that doesn't help, try dropping it to a lower speed/duplex setting and see it it helps.
Well, I need to push 50Mbit/s downstream ... -- Per Jessen, Zürich (18.4°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
