For example (em) driver for Intel-based cards. I'm currently having a system configured with FreeBSD-6.2 RELEASE with PF and ALTQ enabled. This host is configured first with Intel 1-Gigabit Ethernet network card and when it receive big amount of traffic, I don't see any packet errors with netstat but when I switched to the 1-Gigabit fiber optic card, I could see packet errors with this interface. A big amount of traffic were bombarded on the interface around 800Mbps. Here's the sample packet errors received on the system with netstat. Gigabit Intel fiber interface ------------------------------------- # netstat -I em0 -w 1 input (em0) output packets errs bytes packets errs bytes colls 3260 149652 2547816 0 0 0 0 3257 150026 2547756 0 0 0 0 3258 150117 2543396 1 0 42 0 3259 150181 2549320 0 0 0 0 3256 149941 2543244 0 0 0 0 3370 149871 2636122 0 0 0 0 3255 149534 2544688 0 0 0 0 3255 150077 2543966 0 0 0 0 3260 150195 2549320 0 0 0 0 3259 149603 2547816 0 0 0 0 3258 149746 2546312 0 0 0 0 3258 149855 2547756 0 0 0 0 3261 149851 2549320 0 0 0 0 3255 150414 2545410 0 0 0 0 3250 149758 2542282 0 0 0 0 3255 149842 2545410 0 0 0 0 3259 149568 2547756 0 0 0 0 3255 149943 2545502 0 0 0 0 3261 149893 2548658 0 0 0 0 3257 149581 2545530 0 0 0 0 Thank you very much!
