|Oracle Solaris Administration: Network Interfaces and Network Virtualization Oracle Solaris 11 Information Library|
NWAM works with the following other Oracle Solaris networking technologies:
NWAM works with the various Oracle Solaris network virtualization technologies as follows:
Virtual machines: Oracle VM Server for SPARC (formerly Logical Domains) and Oracle VM VirtualBox
NWAM is supported in both Oracle Solaris hosts and guests. NWAM manages only the interfaces that belong to the specified virtual machines and does not interfere with other virtual machines.
Oracle Solaris Zones and stack instances
NWAM works in global zones or in an exclusive stack, non-global zone.
Note - NWAM does not work in a shared stack zone.
Although the current NWAM implementation does not manage VNICs, manually created VNICs persist across reboots and can be created, for example, for assignment to an exclusive-stack zone.
Bridging technology is a method of connecting separate network segments to enable communications between the attached nodes, as if only a single segment were in use. Although the current NWAM implementation does not actively support network configurations that use the bridging technology, you do not need to disable NWAM configuration management prior to using this technology on your system.
Dynamic Reconfiguration and Network Configuration Profiles
On systems that support dynamic reconfiguration (DR) and hot-plug capabilities, these features are readily used only if the active NCP on these systems is DefaultFixed.
If the enabled NCP on these systems is Automatic or any other user-created NCP, then before performing any DR operations, you must first do one of the following steps:
Stop the network service. This action brings down all the network interfaces on the system. Therefore, you must use the system console to stop the service. After you have removed or replaced the device, restart the service.
Remove the IP interface from that active NCP's configuration by using the netcfg command. Then, you can proceed with physically removing or replacing that IP interface's underlying hardware device. If applicable, reconfigure the IP interface after DR is complete.
Traditional networking commands and utilities
At any given time, the system uses either traditional network configuration or NWAM network configuration. If the DefaultFixed NCP is enabled, the system uses traditional network configuration. The system applies the persistent configuration that is stored in the /etc/ipadm/ipadm.conf and /etc/dladm/datalink.conf files when this NCP is enabled. Also, you can use the ipadm and dladm commands to view and alter the network configuration. If an NWAM NCP is enabled, the system ignores the /etc/ipadm/ipadm.conf configuration, and NWAM manages the network configuration according to the policy that is specified in the active NCP.
When NWAM manages network configuration, you can still use the command-line networking utilities, dladm and ipadm, to view the components of your current network configuration.
Note - Making changes to network configuration by using command-line tools is not supported, as those changes might conflict with the policy that is enforced by NWAM.
IP Network Multipathing (IPMP)
NWAM does not currently support the use of IPMP. Before configuring your network to use IPMP, ensure that the DefaultFixed NCP is enabled.
