See https://aws.amazon.com/cli/ for more information about awscli. Move IP within a VPC of the AWS EC2 Path to command line tools for AWS Path to AWS CLI tools Authentication type "key" for AccessKey and SecretAccessKey set via "aws configure", or "role" to use AWS Policies. Authentication type Valid AWS CLI profile name (see ~/.aws/config and 'aws configure') profile name Valid AWS region name (e.g., 'us-west-2') region name VPC private IP address VPC private IP Deprecated IP address param. Use the ip param instead. Deprecated VPC private IP Address Name of the routing table(s), where the route for the IP address should be changed. If declaring multiple routing tables they should be separated by comma. Example: rtb-XXXXXXXX,rtb-YYYYYYYYY routing table name(s) Role to use to query/update the route table route table query/update role Name of the network interface, i.e. eth0 network interface name You can specify an additional label for your IP address here. This label is appended to your interface name. The kernel allows alphanumeric labels up to a maximum length of 15 characters including the interface name and colon (e.g. eth0:foobar1234) Interface label Enable enhanced monitoring using AWS API calls to check route table entry Enhanced Monitoring Name of resource type to lookup in route table. "InstanceId" : EC2 instance ID. (default) "NetworkInterfaceId" : ENI ID.
