## Create a LAG

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

## Update a LAG

* **Note**\
  If you adjust the threshold value for the minimum number of operational connections, ensure that the new value does not cause the LAG to fall below the threshold and become non-operational.

## Associate a connection with a LAG

* **Important**\
  Connectivity to AWS over the connection is interrupted during association.

## Disassociate a connection from a LAG

* **Important**\
  Your connection to AWS is broken off during disassociation.

## Associate a MACsec CKN/CAK with a LAG

* **Note**\
  You cannot modify a MACsec secret key after you associate it with a LAG. If you need to modify the key, disassociate the key from the connection, and then associate a new key with the connection. For information about removing an association, see [Remove the association between a MACsec secret key and a LAG](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_direct_connect/disassociate-key-lag.md).
