vim.host.NetworkSystem

This managed object type describes networking host configuration and serves as the top level container for relevant networking data objects.

extends

vim.ExtensibleManagedObject

Attributes

capabilities (vim.host.NetCapabilities):

Capability vector indicating the available product features.

networkInfo (vim.host.NetworkInfo):

The network configuration and runtime information.

offloadCapabilities (vim.host.NetOffloadCapabilities):

The offload capabilities available on this server.

networkConfig (vim.host.NetworkConfig):

Network configuration information. This information can be applied using the updateNetworkConfig() method. The information is a strict subset of the information available in NetworkInfo.See HostNetworkInfo

dnsConfig (vim.host.DnsConfig):

Client-side DNS configuration.

ipRouteConfig (vim.host.IpRouteConfig):

The IP route configuration.

consoleIpRouteConfig (vim.host.IpRouteConfig):

IP route configuration for the service console. The IP route configuration is global to the entire host. This property is set only if IP routing can be configured for the service console.

Methods

UpdateNetworkConfig(config, changeMode):

Applies the network configuration. This method operates primarily in two modes:replaceormodifymode.replaceWhen called inreplacemode, this method applies the fully specified networking configuration to the networking system.Upon successful completion of the call, the state of networking will match the configuration specified inconfig. In general, objects are created or destroyed to match the elements in the array of configurations. The identifier field in each element in an array of configurations is used to match an existing network entity. The state of existing network entities is patched to match that of the configuration.An exception to this approach applies to the array of PhysicalNic.Config objects. The cardinality of physical network adapters cannot be changed through this operation. Thus, the identifier of every element in the array must match an existing PhysicalNic. If there are fewer elements in the array than there are existing PhysicalNics, then no change is made on the unreferenced PhysicalNic objects.If the call fails, the networking error is returned as an exception and the state of networking reverts to the state prior to the start of the call.modifyWhen called inmodifymode, only changes that are specified are made. For singleton entities like DnsConfig, the state is changed only if the data object is set. For array elements, there is an Operation field that indicates if the element should be added, removed, or edited. In the case of editing or removal, the entity must exist or an exception is thrown. In the case of adding, a specification needs to be provided.It returns device names of vmkernel and service console virtual network adapter added to the system.Currently, the only mode that is implemented is incremental mode. Only add operations are supported for instances. Singleton configuration is not supported. The dynamic privilege check will ensure that users have Host.Config.Network privilege on the host, and Network.Assign privilege on the connecting DVPortGroup, or DVS if connecting to a standalone DVPort. Network.Assign privilege is not required for operations on standard network or for operations performed directly on the hostSee HostConfigChangeMode
