Modifies the description of outbound rules of a security group. You can modify only the description by calling this operation. If you want to modify the policies, port ranges, and authorization objects of security group rules, log on to the Elastic Compute Service (ECS) console.

Description

You can determine an outbound rule by specifying one of the following groups of parameters. You cannot determine a security group rule by specifying only one parameter.

  • Parameters used to specify an outbound security group rule that controls access to a specified CIDR block: IpProtocol, PortRange, SourcePortRange (optional), NicType, Policy (optional), SourceCidrIp, and DestCidrIp.
