Dell network driver
Your switch is designed to forward packets in hardware, and has only the CPU required to figure out what physical path an unknown traffic flow has to take (in -> asic -> out), and program the hardware to do it (read: a calculator has a better CPU than your switch, don't do stupid things that make your switch's CPU work harder).
DELL NETWORK DRIVER SOFTWARE

In the future, consider monitoring the errors on the switch ports with MRTG so you can spot these issues before you have a problem.Įdit: I do see a lot of people referencing negotiation failures on old equipment.
DELL NETWORK DRIVER VERIFICATION
Unless you are prepared to setup a change management system for network changes that requires the verification of speed/duplex (and don't forget flow control) or are willing to deal with occasional mismatches that come from manually specifying these settings on all network devices, then stick with the default configuration of auto/auto. Do not disable autonegotiation between switches unless absolutely required, as physical layer problems can go undetected and result in spanning tree loops. Only disable autonegotiation to end-devices, such as older Gigabit NICs that do not support Gigabit autonegotiation. If you disable autonegotiation, it hides link drops and other physical layer problems. Most failures I have seen are because of 1(a) and you only get in to that situation when you start manually setting speed/duplex settings. Why? Because it is nearly impossible to document the various connections between switches and servers and then follow that documentation when making changes. This depends on the admin, but my experience has shown me that if you manually specify the link speeds and duplex settings, than you are bound to run into speed mismatches.
DELL NETWORK DRIVER MANUAL
I have yet to see a problem with auto-negotiation of network speeds that isn't caused by either (a) a mismatch of manual on one end of the link and auto on the other or (b) a failing component of the link (cable, port, etc). Is it considered good, standard networking practice to disable auto-negotiate and set fixed speeds when setting up networking?.How common are auto-negotiate problems with modern networking hardware?.My questions to those with more server hardware networking expertise: We have now disabled auto-negotiate on our network hardware and set it to a fixed rate of 1000 Mbps (gigabit). This usually works, but not always, and on the morning of January 10th, it didn’t.

The switch that failed had been set to autonegotiate. You can either set the speed manually, or you can let the switch automatically negotiate the highest speed that both sides can work with. There are several possible speeds that a switch can use to communicate (10, 100, or 1000 megabits/second). Michael spent some time doing a post-mortem, and discovered that the problem was a simple configuration problem on the switch. This sounds remarkably like what happened in the Joel Spolsky article Five Whys No particular pattern that we could discern to it.Īfter some digging into it, we saw that the switch was reporting 100 Mbps for the problem port: This has been going on for about two weeks, seemingly at random, on different servers. We recently had a little problem with networking where multiple servers would intermittently lose network connectivity in a fairly painful-to-resolve way (required hard reboot).
