The following is an example of how to view supported features and configured settings of an Ethernet interface. network:Įthtool is a program that displays and changes Ethernet card settings such as auto-negotiation, port speed, duplex mode, and Wake-on-LAN. Then the set-name key can be used to change the device to the desired logial name. The match key is used to find an adapter based on some criteria like MAC address, driver, etc. If you would like control which interface receives a particular logical name use the match and set-name keys. Interface logical names can also be configured via a netplan configuration.

This command provides greater details around the hardware capabilities of specific adapters.

However, in some cases an interface may still use the kernel eth# style of naming. These names can appear as eno1 or enp0s25. Ethernet InterfacesĮthernet interfaces are identified by the system using predictable network interface names. This document is geared toward server administrators and will focus on managing your network on the command line. Ubuntu ships with a number of graphical utilities to configure your network devices.
