Hello, I'm trying to troubleshoot a problem with a fractional (311 mbit/second) gigabit-ethernet line provided to me by a metro access provider. Specifically, it is riding a gig-e port of a 15454. The behavior we are seeing is an occasional loss of packets, adding up to a few percent. When doing a cisco-type ping across the link, we were seeing a consistent 3 to 4 percent loss.
Over what averaging time ? Could this be an example of the "65 second problem", where the router stops dead for one or two seconds out of every 65 seconds ? Regards Marshall Eubanks
For fun, the provider brought it up to 622 mbit/second, and loss dropped considerably, but still hangs at about 1 to 2 percent. There is no question in my mind the issue is with the line, as we've done a wide variety of tests to rule out the local equipment (MSFC2s, FYI). Any clues would be exceptional. -- Alex Rubenstein, AR97, K2AHR, alex () nac net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
