Viewing subnet groups details (Amazon CLI)

At a command prompt, use the command describe-subnet-groups to view a specified subnet group's details.

For Linux, OS X, or Unix:

aws memorydb describe-subnet-groups \
    --subnet-group-name mysubnetgroup

For Windows:

aws memorydb describe-subnet-groups ^
    --subnet-group-name mysubnetgroup

This command should produce output similar to the following:

{
  "subnetgroups": [
    {
      "Subnets": [
        {
          "Identifier": "subnet-060cae3464095de6e", 
          "AvailabilityZone": {
            "Name": "us-east-1a"
          }
        }, 
        {
          "Identifier": "subnet-049d11d4aa78700c3", 
          "AvailabilityZone": {
            "Name": "us-east-1c"
          }
        }, 
        {
          "Identifier": "subnet-0389d4c4157c1edb4", 
          "AvailabilityZone": {
            "Name": "us-east-1d"
          }
        }
      ], 
      "VpcId": "vpc-036a8150d4300bcf2", 
      "Name": "mysubnetgroup", 
      "ARN": "arn:aws:memorydb:us-east-1:53791xzzz7620:subnetgroup/mysubnetgroup", 
      "Description": "test"
    }
  ]
}

To view details on all subnet groups, use the same command but without specifying a subnet group name.

aws memorydb describe-subnet-groups

Using the MemoryDB API, call DescribeSubnetGroups with the following parameters:

SubnetGroupName=mysubnetgroup
