# Updating NDI configuration


Updating the flow NDI® configuration allows you to determine how this flow communicates with the rest of your NDI environment. 

**Important**  
The NDI configuration is available only for **Large** flows. 

## Prerequisites

+  The following procedure assumes that you’ve already created a **Large**flow. 

## Procedure


**To update the NDI configuration of an existing flow (console)**

1. Open the MediaConnect console at [https://console.aws.amazon.com/mediaconnect/](https://console.aws.amazon.com/mediaconnect/).

1. On the **Flows** page, choose the name of the flow that you want to update.

   The details page for that flow appears.

1. In the **NDI configuration** section, choose **Edit**. 

1. Set **Flow NDI support** to **Enabled** to enable NDI, or **Disabled** to disable NDI. 

1. Enter or update the NDI machine name.
   + This name is used as a prefix to help you identify this flow source as an NDI receiver in your network. For example, if you enter **MACHINENAME**, your flow source will appear to your NDI senders as **MACHINENAME (ProgramName)**. 
   + If you don’t enter a name, MediaConnect generates a unique 12-character ID from the flow's ARN. 

1. Update the NDI discovery servers. You can add up to three discovery servers. For each discovery server, provide the following information: 
   + Enter the discovery server IP address (IPv4 format). 
   + Specify a port number if you’re not using the default (5959). 
   + Select the appropriate VPC interface adapter. 

1. Choose **Update**.
