To activate an Elastic IP address for your Transfer Family SFTP or FTPS server, use either the Transfer Family console or the AWS Command Line Interface (AWS CLI).

**Note:** This configuration doesn't apply to FTP activated servers.

### Use the Transfer Family console

To use the Transfer Family console to activate an Elastic IP address for your server, see [Change the endpoint type for your server](https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#change-server-endpoint-type).

### Use the AWS CLI

If you receive errors when you run AWS CLI commands, then see [Troubleshoot AWS CLI errors](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-troubleshooting.html). Also, make sure that [you're using the most recent AWS CLI version](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html).

Complete the following steps:

**Note:** Replace **server-id** with your Transfer Family server ID and **SubnetIds**, **VpcId**, and **AddressAllocationIds** with your subnet, VPC, and address allocation IDs.

1. Run the [stop-sever](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/transfer/stop-server.html) command to stop the server:
    ```plaintext
    $ aws transfer stop-server --server-id s-1234567890abcdef
    ```
    
2. Run the [server-offline](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/transfer/wait/server-offline.html) command to confirm that the server is offline:
    ```plaintext
    $ aws transfer wait server-offline --server-id s-1234567890abcdef
    ```
    
    **Note:** If the server is offline, then the **server-offline** command automatically closes.
    
3. Run the [update-server](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/transfer/update-server.html) command to update the server endpoint type to a VPC:
    ```plaintext
    $ aws transfer update-server --server-id s-1234567890abcdef --endpoint-type VPC --endpoint-details SubnetIds=subnet-123abc,VpcId=vpc-123abc
    ```
    
4. Run the [update-server](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/transfer/update-server.html) command to associate the VPC endpoint to an Elastic IP address:
    ```plaintext
    $ aws transfer update-server --server-id s-1234567890abcdef --endpoint-type VPC --endpoint-details AddressAllocationIds=eipalloc-123456abcdef,SubnetIds=subnet-123abc,VpcId=vpc-123abc
    ```
    
5. Run the [start-server](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/transfer/start-server.html) command to start the server:
    ```plaintext
    $ aws transfer start-server --server-id s-1234567890abcdef
    ```
    

To use the Boto3 AWS SDK to update the server endpoint type, see [Updating the server EndpointType using the API](https://docs.aws.amazon.com/transfer/latest/userguide/update-endpoint-type-vpc.html#update-endpoint-cli).
