Might want to query your provider as to where the rate limitting is being done. In some cases, if rate limit is being done egress from the layer 3 infracture towards the MAN layer 2 equipment, there might be a lack of processing power on that device, causing the drops. Of course this will depend on the type of device and whether the rate limiting is being done on hardware or not too. Sush
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. 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 --
