Updates the specified CIDR block of a VCN. The new CIDR IP range must meet the following criteria:
Must be valid. - Must not overlap with another CIDR block in the VCN, a CIDR block of a peered VCN, or the on-premises network CIDR block. - Must not exceed the limit of CIDR blocks allowed per VCN. - Must include IP addresses from the original CIDR block that are used in the VCN’s existing route rules. - No IP address in an existing subnet should be outside of the new CIDR block range.
Note: Modifying a CIDR block places your VCN in an updating state until the changes are complete. You cannot create or update the VCN’s subnets, VLANs, LPGs, or route tables during this operation. The time to completion can vary depending on the size of your network. Updating a small network could take about a minute, and updating a large network could take up to an hour. You can use the GetWorkRequest operation to check the status of the update.
The new CIDR IP address.
The CIDR IP address to update.
The OCID of the VCN.
Provide input to this command as a JSON document from a file using the file://path-to/file syntax.
--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
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.
The maximum time to wait for the work request to reach the state defined by
--wait-for-state. Defaults to 1200 seconds.
This operation asynchronously creates, modifies or deletes a resource and uses a work request to track the progress of the operation. Specify this option to perform the action and then wait until the work request reaches a certain state. Multiple states can be specified, returning on the first state. For example,
--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:
ACCEPTED, FAILED, IN_PROGRESS, SUCCEEDED
--wait-interval-seconds to see whether the work request to see if it has reached the state defined by
--wait-for-state. Defaults to 30 seconds.
oci --help for help on global parameters.
