Description
===========

Updates the specified subnet.


Usage
=====

   oci network subnet update [OPTIONS]


Required Parameters
===================

--subnet-id [text]

The OCID of the subnet.


Optional Parameters
===================

--cidr-block [text]

The CIDR block of the subnet. The new CIDR block must meet the
following criteria:

* Must be valid. - The CIDR block’s IP range must be completely within
  one of the VCN’s CIDR block ranges. - The old and new CIDR block
  ranges must use the same network address. Example: *10.0.0.0/25* and
  *10.0.0.0/24*. - Must contain all IP addresses in use in the old
  CIDR range. - The new CIDR range’s broadcast address (last IP
  address of CIDR range) must not be an IP address in use in the old
  CIDR range.

**Note:** If you are changing the CIDR block, you cannot create VNICs
or private IPs for this resource while the update is in progress.

Example:

   172.16.0.0/16

--defined-tags [complex type]

Defined tags for this resource. Each key is predefined and scoped to a
namespace. For more information, see Resource Tags.

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.

--dhcp-options-id [text]

The OCID of the set of DHCP options the subnet will use.

--display-name [text]

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

--force

Perform update without prompting for confirmation.

--freeform-tags [complex type]

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.

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.

--from-json [text]

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/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--if-match [text]

For optimistic concurrency control. In the PUT or DELETE call for a
resource, set the *if-match* parameter to the value of the etag from a
previous GET or POST response for that resource. The resource will be
updated or deleted only if the etag you provide matches the resource’s
current etag value.

--ipv6-cidr-block [text]

This is the IPv6 CIDR block for the subnet’s IP address space. The
subnet size is always /64. See IPv6 Addresses. The provided CIDR must
maintain the following rules -

1. The IPv6 CIDR block is valid and correctly formatted. b. The IPv6
   CIDR is within the parent VCN IPv6 range.

Example:

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

--ipv6-cidr-blocks [complex type]

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.

--max-wait-seconds [integer]

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

--route-table-id [text]

The OCID of the route table the subnet will use.

--security-list-ids [complex type]

The OCIDs of the security list or lists the subnet will use. This
replaces the entire current set of security lists. 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.

--wait-for-state [text]

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

--wait-interval-seconds [integer]

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.

Examples
========

Copy the following CLI commands into a file named example.sh. Run the
command by typing “bash example.sh” and replacing the example
parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-
like shell. You need to set up the OCI configuration and appropriate
security policies before trying the examples.
