NAME

ethtool - query or control network driver and hardware settings

Fork of Meize's RealtekRTL8111 Network driver for OS X - RehabMan/OS-X-Realtek-Network. Ethtool is a Network Interface Card configuration command that allows us to retrieve information and change our NIC settings. The information includes Speed, Duplex, Auto-Negotiation, and many other parameters. To continue, we have to know the name of the network interface card. To get the name of the network interface card, just run.

SYNOPSIS

IBM Developer 正在整合其语言站点组合。 请根据您未来的需求考虑以下资源： IBM Developer 网站 (英文) IBM 中国网站 IBM. Currently, my NIC enx00e04c42a3fe is working in Full duplex mode at 100 Mbps speed. To change it, let’s say in Full duplex mode at 10 Mbps speed, run ethtool as follows: $ sudo ethtool -s enx00e04c42a3fe speed 10 duplex full autoneg off. As you can see, the speed is changed to 10Mbps and the duplex mode is full.

ethtoolis used to query and control network device driver and hardwaresettings, particularly for wired Ethernet devices.

devnameis the name of the network device on which ethtool should operate.
