# DestroyPort

## 1. API Description

This API is used to release a port.

#### Prerequisites

Before releasing a port, you can call [`DescribePorts`](https://docs.console.zenlayer.com/api-reference/networking/sdn/describeports#DescribePorts) to query port list.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

* <mark style="color:blue;">This operation is irreversible. Once the operation is successful, the port will be completely released. Please operate with caution.</mark>
* <mark style="color:blue;">Only operations on ports in recycle bin are supported.</mark>
* <mark style="color:blue;">This API is an async API. A request ID is returned after the release request is sent. However, it does not mean the releasing has been completed. The status of the port will be</mark> <mark style="color:blue;">`DESTROYING`</mark> <mark style="color:blue;">during the releasing. You can use</mark> [<mark style="color:purple;">`DescribePorts`</mark>](https://docs.console.zenlayer.com/api-reference/networking/sdn/describeports#describeports) <mark style="color:blue;">to query the status of the port. If the status of the port changes</mark> <mark style="color:blue;">`DESTROYING`</mark> <mark style="color:blue;">to</mark> <mark style="color:blue;">`DESTROYED`</mark><mark style="color:blue;">, it means that the port has been released successfully. Any operations on the port are not allowed while releasing.</mark>
