After increasing the tx and rx buffers for the kernel tulip driver, it has been working better for my p430 nic. I don't know why this would have a measurable affect. I am confused about something else too: When running a single port, I can run 50Mbps w/out dropping more than 1 in 6 million packets. If I run 10Mbps on 4 ports, I see 1000 per million packets dropped per port. However, the driver counters do not show any significant number of drops. More interestingly, it seems some packets are just lost on the wire, and are never accounted for anywhere: I have zero receive or transmit errors, but one port claims to have transmitted 322589 packets, and the port it is connected to (via cross-over cable) has only received 322051 packets. This spread increases over time, so it is not just packets in transit... Any ideas where these lost packets are going, or how to find out?? -- Ben Greear <[email protected]> <Ben_Greear AT excite.com> President of Candela Technologies Inc http://www.candelatech.com ScryMUD: http://scry.wanfear.com http://scry.wanfear.com/~greear _______________________________________________ tulip mailing list, [email protected] To change to digest mode or unsubscribe visit http://www.scyld.com/mailman/listinfo/tulip
