NAME

DESCRIPTION

For the purposes of access control, you must provide the OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the compartment where you want the subnet to reside. Notice that the subnet doesn’t have to be in the same compartment as the VCN, route tables, or other Networking Service components. If you’re not sure which compartment to use, put the subnet in the same compartment as the VCN. For more information about compartments and access control, see Overview of the IAM Service <https://docs.cloud.oracle.com/iaas/Content/Identity/Concepts/overview.htm>. For information about OCIDs, see Resource Identifiers <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm>.

You may optionally associate a route table with the subnet. If you don’t, the subnet will use the VCN’s default route table. For more information about route tables, see Route Tables <https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingroutetables.htm>.

You may optionally associate a security list with the subnet. If you don’t, the subnet will use the VCN’s default security list. For more information about security lists, see Security Lists <https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/securitylists.htm>.

You may optionally associate a set of DHCP options with the subnet. If you don’t, the subnet will use the VCN’s default set. For more information about DHCP options, see DHCP Options <https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingDHCP.htm>.

You may optionally specify a display name for the subnet, otherwise a default is provided. It does not have to be unique, and you can change it. Avoid entering confidential information.

You can also add a DNS label for the subnet, which is required if you want the Internet and VCN Resolver to resolve hostnames for instances in the subnet. For more information, see DNS in Your Virtual Cloud Network <https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/dns.htm>.

USAGE

oci network subnet create [OPTIONS]

REQUIRED PARAMETERS

The CIDR IP address range of the subnet. The CIDR must maintain the following rules -

Example:

10.0.1.0/24

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the compartment to contain the subnet.

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the VCN to contain the subnet.

OPTIONAL PARAMETERS

Controls whether the subnet is regional or specific to an availability domain. Oracle recommends creating regional subnets because they’re more flexible and make it easier to implement failover across availability domains. Originally, AD-specific subnets were the only kind available to use.

To create a regional subnet, omit this attribute. Then any resources later created in this subnet (such as a Compute instance) can be created in any availability domain in the region.

To instead create an AD-specific subnet, set this attribute to the availability domain you want this subnet to be in. Then any resources later created in this subnet can only be created in that availability domain.

Example:

Uocm:PHX-AD-1

Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/resourcetags.htm>.

Example:

{"Operations": {"CostCenter": "42"}}

This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the set of DHCP options the subnet will use. If you don’t provide a value, the subnet uses the VCN’s default set of DHCP options.

A user-friendly name. Does not have to be unique, and it’s changeable. Avoid entering confidential information.

A DNS label for the subnet, used in conjunction with the VNIC’s hostname and VCN’s DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet (for example, bminstance-1.subnet123.vcn1.oraclevcn.com). Must be an alphanumeric string that begins with a letter and is unique within the VCN. The value cannot be changed.

This value must be set if you want to use the Internet and VCN Resolver to resolve the hostnames of instances in the subnet. It can only be set if the VCN itself was created with a DNS label.

For more information, see DNS in Your Virtual Cloud Network <https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/dns.htm>.

Example:

subnet123

Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/resourcetags.htm>.

Example:

{"Department": "Finance"}

This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

Use this to enable IPv6 addressing for this subnet. The VCN must be enabled for IPv6. You can’t change this subnet characteristic later. All subnets are /64 in size. The subnet portion of the IPv6 address is the fourth hextet from the left (1111 in the following example).

For important details about IPv6 addressing in a VCN, see IPv6 Addresses <https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/ipv6.htm>.

Example:

2001:0db8:0123:1111::/64

The list of all IPv6 CIDR blocks (Oracle allocated IPv6 GUA, ULA or private IPv6 CIDR blocks, BYOIPv6 CIDR blocks) for the subnet that meets the following criteria: - The CIDR blocks must be valid. - Multiple CIDR blocks must not overlap each other or the on-premises network CIDR block. - The number of CIDR blocks must not exceed the limit of IPv6 CIDR blocks allowed to a subnet. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

The maximum time to wait for the resource to reach the lifecycle state defined by --wait-for-state. Defaults to 1200 seconds.

Whether to disallow ingress internet traffic to VNICs within this subnet. Defaults to false.

For IPv6, if prohibitInternetIngress is set to true, internet access is not allowed for any IPv6s assigned to VNICs in the subnet. Otherwise, ingress internet traffic is allowed by default.

prohibitPublicIpOnVnic will be set to the value of prohibitInternetIngress to dictate IPv4 behavior in this subnet. Only one or the other flag should be specified.

Example:

true

Whether VNICs within this subnet can have public IP addresses. Defaults to false, which means VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch (with the –assign-public-ip flag). If –prohibit-public-ip-on-vnic is set to true, VNICs created in this subnet cannot have public IP addresses (i.e., it’s a private subnet).

Example:

true

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the route table the subnet will use. If you don’t provide a value, the subnet uses the VCN’s default route table.

The OCIDs of the security list or lists the subnet will use. If you don’t provide a value, the subnet uses the VCN’s default security list. Remember that security lists are associated with the subnet, but the rules are applied to the individual VNICs in the subnet. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Example:

'["ocid1.securitylist.oc1.phx.aaaaaaaadyndu2n3hcmdsjfiljwyq7vpxsvv7ynp4ori7aealcvhzicnzhyq"]'

This operation creates, modifies or deletes a resource that has a defined lifecycle state. Specify this option to perform the action and then wait until the resource reaches a given lifecycle state. Multiple states can be specified, returning on the first state. For example, --wait-for-state SUCCEEDED --wait-for-state FAILED would return on whichever lifecycle state is reached first. If timeout is reached, a return code of 2 is returned. For any other error, a return code of 1 is returned.

Accepted values are:

AVAILABLE, PROVISIONING, TERMINATED, TERMINATING, UPDATING

Check every --wait-interval-seconds to see whether the resource to see if it has reached the lifecycle state defined by --wait-for-state. Defaults to 30 seconds.
