How Do I Enable ICMP Security Group Rules?

If the health check protocol of a load balancer is UDP, you must enable the ICMP security group rules of the backend server.


  1. Log in to the ECS console, find the ECS corresponding to the node in the CCE cluster, and click the ECS name. The ECS details page is displayed.


    You only need to change the security group rules for any node in the cluster where the application is located. Add rules and do not modify the original security group rules.

  2. On the Security Groups tab page, click Modify Security Group Rule.

  3. Click Add Rule to add an inbound rule for the ECS. For details, see Figure 2. Click OK.
