Binding or Unbinding an EIP

Scenario

After a CDM cluster is created, you can bind an EIP to or unbind it from the CDM cluster.

• If CDM needs to access a local or Internet data source, or a cloud service in another VPC, bind an EIP to the CDM cluster or use a NAT gateway to enable the CDM cluster to share the EIP with ECSs to access the Internet..
• To create an EIP exception notification, choose Authorize EIP Check > Create Agency on the Cluster Management page. The EIP exception notification takes effect only after the VPC policy agency of the corresponding region is created on the IAM management console.

If SSL encryption is configured for the access channel of a local data source, CDM cannot connect to the data source using the EIP.

Prerequisites

• You have created a CDM cluster.
• Your EIP quota is sufficient.

Procedure

1. Log in to the CDM console. In the navigation pane, choose Cluster Management.
