This topic describes how to disassociate a Virtual Private Cloud (VPC) network from a Dynamic Host Configuration Protocol (DHCP) options set. After a VPC network is disassociated from a DHCP options set, Elastic Compute Service (ECS) instances in the VPC network can no longer use the configurations of the DHCP options set.


  1. Log on to the VPC console.
  2. In the left-side navigation pane, click DHCP Options Sets.
  3. On the DHCP Options Sets page, click the instance ID of the target DHCP options set.
  4. In the Associated VPCs section, find the VPC to be disassociated, and click Disassociate in the Actions column.
  5. In the message that appears, click OK.
