Reference documentation and code samples for the Backup and DR Service v1 API class NetworkInterface.
A network interface resource attached to an instance.
s
public RepeatedField<AccessConfig> AccessConfigs { get; }
Optional. An array of configurations for this interface. Currently, only
one access config,ONE_TO_ONE_NAT is supported. If there are no
accessConfigs specified, then this instance will have
no external internet access.
Optional. An IPv4 internal IP address to assign to the instance for this
network interface. If not specified by the user, an unused internal IP is
assigned by the system.
public RepeatedField<AccessConfig> Ipv6AccessConfigs { get; }
Optional. An array of IPv6 access configurations for this interface.
Currently, only one IPv6 access config, DIRECT_IPV6, is supported. If there
is no ipv6AccessConfig specified, then this instance will
have no external IPv6 Internet access.
public NetworkInterface.Types.Ipv6AccessType Ipv6AccessType { get; set; }
Optional. [Output Only] One of EXTERNAL, INTERNAL to indicate whether the
IP can be accessed from the Internet. This field is always inherited from
its subnetwork.
Optional. An IPv6 internal network address for this network interface. To
use a static internal IP address, it must be unused and in the same region
as the instance's zone. If not specified, Google Cloud will automatically
assign an internal IPv6 address from the instance's subnetwork.
Optional. The URL of the network attachment that this interface should
connect to in the following format:
projects/{project_number}/regions/{region_name}/networkAttachments/{network_attachment_name}.
Optional. The networking queue count that's specified by users for the
network interface. Both Rx and Tx queues will be set to this number. It'll
be empty if not specified by the users.
