Associates a security group with a Network Load Balancer (NLB) instance.
Operation description
-
Make sure that you have created a security group. For more information about how to create a security group, see CreateSecurityGroup .
-
An NLB instance can be associated with up to four security groups.
-
You can query the security groups that are associated with an NLB instance by calling the GetLoadBalancerAttribute operation.
-
LoadBalancerJoinSecurityGroup is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the GetJobStatus operation to query the status of a task.
- If the task is in the Succeeded state, the security group is associated.
- If the task is in the Processing state, the security group is being associated. In this case, you can perform only query operations.
