You use three commands to administer network configuration in this Oracle Solaris release. These commands are described in the sections that follow.
The dladm is used to configure the datalinks on a system as well as manage the following types of network configuration:
Physical interfaces – Ethernet, wireless, and InfiniBand
Virtual networking features – Etherstubs, VNICs, and IP tunnels
Switch features – Link aggregations, VLANs, and bridging technologies
Device characteristics – Speed, duplexing, priority, and feature negotiation
The dladm command replaces the ndd command that is used to configure protocol properties in previous Oracle Solaris releases.
The ipadm command replaces the ifconfig command and is used to configured IP interfaces and addresses. Unlike the ifconfig command, ipadm implements persistent network configuration.
The command also replaces the ndd command that was previously used to configure protocol properties.
The /etc/defaultrouter file is removed in Oracle Solaris 11.4. Thus, you must use the route command to configure persistent and default routes which are then stored in the network routing tables. See Creating Persistent (Static) Routes in Configuring an Oracle Solaris 11.4 System as a Router or a Load Balancer.
In Oracle Solaris 11.4, the scope of these commands are more limited. The netcfg command only manages external network modifiers (ENMs). The netadm command is used to enable and disable ENMs and to display information about ENMs and their states.
