In this tutorial, we will show you how to check the available Network Interface Card (NIC) and other details such as interface name, associated IP address, MAC address and interface speed. If yes, check other configuration details that are compatible with existing interfaces. The following are standard variables found in the file used for static or dynamic IPv4 configuration.Server primary interface would be configured as part of the server build activity, but sometimes you may need to configure an additional network interface in Linux for several reasons.Īn additional interface will be configured for network bonding/teaming, high availability or a separate interface that is used for application requirements or backups.īefore adding a new interface, check if the system has any free interfaces.
These files are usually named /etc/sysconfig/network-scripts/ifcfg-name, where name refers to the name of the device or connection that the configuration file controls.

Connection configuration files control the software interfaces for individual network devices. It is also possible to configure the network by directly editing the connection configuration files. The connection is bound to the network interface with this MAC address. The connection is bound to the network interface with this name. Exactly the same as IPv4.Īutomatically activate this connection at boot. Modify /etc/nf to use this domain in the search directive. If more than one address is set for the connection, IPV6_SECONDARIES takes a double-quoted list of space- delimited address/prefix definitions. Sets static IPv6 address, ::n1etwork prefix, and default gateway. Ignore DNS server information from the DHCP server.Ĭonfigures network settings using SLAAC from router advertisements.Ĭonfigures network settings by using DHCPv6, but not SLAAC. If more than one is set for the connection, then instead of 0, the ifcfg-* directives end with 1, 2, 3 and so on. Sets static IPv4 address, network prefix, and default gateway. If static addresses are also set, will not bring those up until we have information from DHCPv4. Looks for configuration settings from a DHCPv4 server.

Comparison of nm-settings and ifcfg-* Directive NMCLI CON MOD
The following table maps some of the key setting names to ifcfg-* directives. After doing so, run nmcli con reload so that NetworkManager reads the configuration changes.įor backward-compatibility reasons, the directives saved in that file have different names and syntax than the nm-settings(5) names. That file can also be manually edited with a text editor. DESCRIBING CONNECTION CONFIGURATION FILESīy default, changes made with nmcli con mod name are automatically saved to /etc/ sysconfig/network-scripts/ifcfg-name.
