Elastic Compute Service:DeleteNetworkInterface

Last Updated:Sep 29, 2024

Deletes an elastic network interface (ENI) in a region. DeleteNetworkInterface is an asynchronous operation.

Operation description

Take note of the following items:

  • The ENI to be deleted must be in the Available state.

  • If the ENI to be deleted is attached to an Elastic Compute Service (ECS) instance, you must detach the ENI from the instance before you can delete the ENI. To detach the ENI, you can call the DetachNetworkInterface operation.

  • After an ENI is deleted, the following situations occur:

    • All private IP addresses (including primary and secondary private IP addresses) of the ENI are automatically released.
    • The ENI is automatically removed from all security groups.
  • The DeleteNetworkInterface operation is an asynchronous operation. After this operation is called to delete an ENI, you can check the status or events of the ENI to determine whether the ENI is deleted. The following figure shows the transitions between the states of the ENI.

    • If the ENI is in the Deleting state, the ENI deletion request is sent and the ENI is being deleted.
    • If the ENI is not found, the ENI is deleted.
    • If the ENI is stuck in the Deleting state, the ENI fails to be deleted. You can re-initiate the request to delete the ENI.

For information about examples on how to call the DeleteNetworkInterface operation, see Delete an ENI.
