Binding or Unbinding an EIP
Scenario
After creating a CDM cluster, you can bind an EIP to or unbind an EIP from the 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. For details, see Adding a SNAT Rule.
- 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.
