For the test, I have configured the port #2 (UART2) to be used at 230400 speed rate and in raw mode (no control, no parity, no breaks). For this purpose, we'll use Macchanger, an utility for manipulating MAC addresses, for which we'll create a systemd unit to start it automatically on boot. I have a 10 Gbps test bed to test the capability of server, equipped with 10Gig switch and traffic is generated from many 1Gig machines. Bonding allows you to aggregate multiple ports into a single group, effectively combining the bandwidth into a single connection. - I can find plenty docs for xen kernel-based setups (on howtoforge and such) but those instructions don't for for XenServer at all. RX errors 0 TX errors 0. Also we have done the same tests using 3. RX frame accounts for the incoming frames that were misaligned. 2018 Leave a comment on The reason for increasing RX overruns on the network adapter I noticed once on one of the servers that the RX overruns value is growing slightly. ifconfig for Linux is part of the package net-tools, released as the latest version 1. 4 Mb) TX bytes:3168716203 (3021. I know the subject line is very similar to: destination host unreachable but the problem with my machine appears to be somewhat different from that th | The UNIX and Linux Forums Cannot ping gateway The UNIX and Linux Forums. Short of booting a live Linux distro on each Windows box, is there some tool available for detecting the source of the RX overruns?--buck. The root cause of this could be a bad cable, or a bad interface on either the machine or the switch.
