X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Jun 2003 19:49:58 -0000 Can anyone explain what are interface errors in netstat -I? I assume they are CRC, undersize frames, etc. Anyway to get details on which errors are occurring? Also, I'm now not sure that is what the error counter means - a box doing about 20k pps normally runs with no reported interface errors - however, when the application crashed, it got a spike of input interface errors. The application crashing should not have affected MAC layer packets, so do interface errors also include some TCP layer errors?
