http_put_response_hop_limit class-attribute instance-attribute

http_tokens class-attribute instance-attribute

Indicates whether IMDSv2 is required.

  • optional - IMDSv2 is optional. You can choose whether to send a session token in your instance metadata retrieval requests. If you retrieve IAM role credentials without a session token, you receive the IMDSv1 role credentials. If you retrieve IAM role credentials using a valid session token, you receive the IMDSv2 role credentials.

  • required - IMDSv2 is required. You must send a session token in your instance metadata retrieval requests. With this option, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

Default: If the value of ImdsSupport for the Amazon Machine Image (AMI) for your instance is v2.0, the default is required.
