Cabling seems fine as neither the switch nor the sysctl info for the device show any errors/collisions/etc, however there is one odd one, which is "dev.bce.1.stat_IfHCInBadOctets: 539369". See [1] below for full sysctl output. The switch shows no errors but for "Dropped packets 683868". A quick check of the #'s is showing an error rate of 8.6e-6, or about one byte out of 100,000. That's much better than what TCP/IP and ethernet were designed for. At a guess, your box or the switch occasionally gets busy enough that it drops a few packets now and again. Regards, -- -Chuck
