Viewing subnet group details

The following procedures show you how to view details a subnet group.

Viewing details of subnet groups (console)

To view details of a subnet group (Console)

  1. Sign in to the Amazon Web Services Management Console and open the MemoryDB for Redis console at https://console.amazonaws.cn/memorydb/.

  2. In the left navigation pane, choose Subnet Groups.

  3. On the Subnet groups page, choose the subnet group under Name or enter the subnet group's name in the search bar.

  4. On the Subnet groups page, choose the subnet group under Name or enter the subnet group's name in the search bar.

  5. Under Subnet group settings you can view the name,description, VPC ID and Amazon Resource Name (ARN) of the subnet group.

  6. Under Subnets you can view the Availability Zones, Subnet IDs and CIDR blocks of the subnet group

  7. Under Tags you can view any tags associated with the subnet group.

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

For more information, see the Amazon CLI topic describe-subnet-groups.

Viewing subnet groups (MemoryDB API)

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

SubnetGroupName=mysubnetgroup

    ?Action=UpdateSubnetGroup
    &Description=New%20description
    &SubnetGroupName=mysubnetgroup
    &SubnetIds.member.1=subnet-42df9c3a
