In this A. From examining basic interface settings to enabling advanced features or configuring specific network parameters, these use cases illustrate how ethtool can be ethtool is used to query and control network device driver and hardware settings, particularly for wired Ethernet devices. Many people use it. Luckily, the ‘ethtool’ command is readily available on most package management systems, which makes the installation process straightforward once The supported speeds listed by ethtool reflect the controller capability and are not based on the transceiver or cable capability. devname is the name of the network device on which ethtool should operate. You can change network card speed, auto-negotiation, wake on LAN setting, duplex mode using this tool in Linux. It’s not possible to show how every option work in this article due to the scope and hardware limitation of my computer. Use ethtool option -p, which will make the corresponding LED of physical port to blink. [root@localhost To obtain the duplex and speed of the interface, you need to use the ioctl(fd, SIOCETHTOOL, struct ifreq *) with the ifr_data pointing to a struct ethtool_cmd having cmd = H ow do I display dropped packets per interface on Linux operating systems from the command line option? How can I determine why a Linux The example given here shows a normal working interface. Ethtool Sample Application The Ethtool sample application shows an implementation of an ethtool-like API and provides a console environment that allows its use to query and change Ethernet card First things first we need to determine what Ethernet adaptor you are using. ethtool is a command line utility used to query and control network device driver and hardware settings, particularly for wired Ethernet devices.
