**Example 1: To enable IMDSv2** The following ``modify-instance-metadata-options`` example configures the use of IMDSv2 on the specified instance. :: aws ec2 modify-instance-metadata-options \ --instance-id i-1234567898abcdef0 \ --http-tokens required \ --http-endpoint enabled Output:: { "InstanceId": "i-1234567898abcdef0", "InstanceMetadataOptions": { "State": "pending", "HttpTokens": "required", "HttpPutResponseHopLimit": 1, "HttpEndpoint": "enabled" } } For more information, see `Instance metadata and user data <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html>`__ in the *Amazon Elastic Compute Cloud User Guide for Linux Instances*. **Example 2: To disable instance metadata** The following ``modify-instance-metadata-options`` example disables the use of all versions of instance metadata on the specified instance. :: aws ec2 modify-instance-metadata-options \ --instance-id i-1234567898abcdef0 \ --http-endpoint disabled Output:: { "InstanceId": "i-1234567898abcdef0", "InstanceMetadataOptions": { "State": "pending", "HttpTokens": "required", "HttpPutResponseHopLimit": 1, "HttpEndpoint": "disabled" } } For more information, see `Instance metadata and user data <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html>`__ in the *Amazon Elastic Compute Cloud User Guide for Linux Instances*. **Example 3: To enable instance metadata IPv6 endpoint for your instance** The following ``modify-instance-metadata-options`` example shows you how to turn on the IPv6 endpoint for the instance metadata service. :: aws ec2 modify-instance-metadata-options \ --instance-id i-1234567898abcdef0 \ --http-protocol-ipv6 enabled \ --http-endpoint enabled Output:: { "InstanceId": "i-1234567898abcdef0", "InstanceMetadataOptions": { "State": "pending", "HttpTokens": "required", "HttpPutResponseHopLimit": 1, "HttpEndpoint": "enabled", HttpProtocolIpv6": "enabled" } } By default, the IPv6 endpoint is disabled. This is true even if you have launched an instance into an IPv6-only subnet. The IPv6 endpoint for IMDS is only accessible on instances built on the Nitro System. For more information, see `Instance metadata and user data <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html>`__ in the *Amazon Elastic Compute Cloud User Guide for Linux Instances*.
