## Viewing details of subnet groups (console)
<a name="subnetgroups.Viewingclusters.viewdetails"></a>

**To view details of a subnet group (Console)**

1. Sign in to the AWS Management Console and open the MemoryDB console at [https://console.aws.amazon.com/memorydb/](https://console.aws.amazon.com/memorydb/).

1. In the left navigation pane, choose **Subnet Groups**.

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

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

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

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

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

## Viewing subnet groups details (AWS CLI)
<a name="subnetgroups.Viewing.cli"></a>

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

For Linux, macOS, 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
```
