Deleting a Subnet

Delete a subnet from a virtual cloud network (VCN).

Before you can delete a subnet, it must have no instances, load balancers, OCI database systems, or orphaned mount targets in it. For more information, see Subnet or VCN Deletion.

If the subnet is empty, its state changes to TERMINATING briefly and then TERMINATED. If the subnet is not empty, you get an error indicating that there are still instances or other resources in it that you must delete first.

    1. Open the navigation menu, click Networking, and then click Virtual cloud networks.
    2. Click the name of the VCN that contains the subnet.
    3. Click Subnets.
    4. Click the subnet that you're interested in.
    5. On the subnet details page, click Terminate.
    6. When prompted, confirm the deletion.

  • Use the network subnet update command and required parameters to edit a subnet:

    oci network subnet delete --subnet-id ocid ... [OPTIONS]

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the DeleteSubnet operation to delete a subnet.
