# Create a LAG at an Direct Connect endpoint
<a name="create-lag"></a>

You can create a LAG by provisioning new connections, or aggregating existing connections.

You cannot create a LAG with new connections if this results in you exceeding the overall connections limit for the Region.

To create a LAG from existing connections, the connections must be on the same AWS device (terminate at the same Direct Connect endpoint). They must also use the same bandwidth. You cannot migrate a connection from an existing LAG if removing the connection causes the original LAG to fall below its setting for the minimum number of operational connections.

**Important**  
For existing connections, connectivity to AWS is interrupted during the creation of the LAG.

**To create a LAG with new connections**

1. Open the **Direct Connect** console at [https://console.aws.amazon.com/directconnect/v2/home](https://console.aws.amazon.com/directconnect/v2/home).

1. In the navigation pane, choose **LAGs**.

1. Choose **Create LAG**.

1. Under** Lag creation type**, choose **Request new connections**, and provide the following information:
   + **LAG name**: A name for the LAG.
   + **Location**: The location for the LAG.
   + **Port speed**: The port speed for the connections.
   + **Number of new connections**: The number of new connections to create. You can have a maximum of four connections when the port speed is 1G or 10G, or two when the port speed is 100 Gbps or 400 Gbps.
   + (Optional) Configure MAC security (MACsec) for the connection. Under **Additional Settings**, select **Request a MACsec capable port**.

     MACsec is only available on dedicated connections.
   + (Optional) Add or remove a tag.

     [Add a tag] Choose **Add tag** and do the following:
     + For **Key**, enter the key name.
     + For **Value**, enter the key value.

     [Remove a tag] Next to the tag, choose **Remove tag**.

1. Choose **Create LAG**.
