Function

This API is used to create a security group rule.

URI

POST /v2.0/security-group-rules

Request Parameters

**Table 1** Request parameter
Parameter	Type	Mandatory	Description
security_group_rule	security_group_rule object	Yes	Specifies the security group rule. For details, see Table 2.

**Table 2** **Security Group Rule** objects
Attribute	Mandatory	Type	Description
description	No	String	Provides supplementary information about the security group rule.
security_group_id	Yes	String	Specifies the ID of the belonged security group.
remote_group_id	No	String	Specifies the peer ID of the belonged security group. This parameter is mutually exclusive with remote_ip_prefixand remote_address_group_id.
direction	Yes	String	Specifies the direction of the traffic for which the security group rule takes effect. The value can be ingress or egress.
remote_ip_prefix	No	String	Specifies the peer IP address segment. This parameter is mutually exclusive with remote_group_id and remote_address_group_id.
protocol	No	String	Specifies the protocol type or the IP protocol number. The value can be tcp, udp, icmp or an IP protocol number
port_range_max	No	Integer	Specifies the maximum port number. When ICMP is used, the value is the ICMP code. The value ranges from 1 to 65535. (The value ranges from 0 to 255 when it indicates the code.)
port_range_min	No	Integer	Specifies the minimum port number. If the ICMP protocol is used, this parameter indicates the ICMP type. When the TCP or UDP protocol is used, both port_range_max and port_range_min must be specified, and the port_range_max value must be greater than the port_range_min value. When the ICMP protocol is used, if you specify the ICMP code (port_range_max), you must also specify the ICMP type (port_range_min). The value ranges from 1 to 65535. (The value ranges from 0 to 255 when it indicates the code.)
ethertype	No	String	Specifies the network type. The value can be IPv4 or IPv6.
remote_address_group_id	No	String	Specifies the remote IP address group ID. You can log in to the management console and view the ID on the IP address group page. This parameter is mutually exclusive with parameters remote_ip_prefix and remote_group_id.

Example Request

Create an outbound rule in the security group whose ID is 5cb9c1ee-00e0-4d0f-9623-55463cd26ff8. Set protocol to tcp, and remote_ip_prefix to 10.10.0.0/24.

Parameter	Type	Description
security_group_rule	security_group_rule object	Specifies the security group rule. For details, see Table 4.

**Table 4** **Security Group Rule** objects
Attribute	Type	Description
id	String	Specifies the security group rule ID. This parameter is not mandatory when you query security group rules.
description	String	Provides supplementary information about the security group rule.
security_group_id	String	Specifies the ID of the belonged security group.
remote_group_id	String	Specifies the peer ID of the belonged security group.
direction	String	Specifies the direction of the traffic for which the security group rule takes effect.
remote_ip_prefix	String	Specifies the peer IP address segment.
protocol	String	Specifies the protocol type or the IP protocol number.
port_range_max	Integer	Specifies the maximum port number. When ICMP is used, the value is the ICMP code.
port_range_min	Integer	Specifies the minimum port number. If the ICMP protocol is used, this parameter indicates the ICMP type. When the TCP or UDP protocol is used, both port_range_max and port_range_min must be specified, and the port_range_max value must be greater than the port_range_min value. When the ICMP protocol is used, if you specify the ICMP code (port_range_max), you must also specify the ICMP type (port_range_min).
ethertype	String	Specifies the network type. IPv4 and IPv6 are supported.
tenant_id	String	Specifies the project ID.
remote_address_group_id	String	Specifies the remote IP address group ID. The value is mutually exclusive with parameters remote_ip_prefix and remote_group_id.
project_id	String	Specifies the project ID. For details about how to obtain a project ID, see Obtaining a Project ID.
created_at	String	Specifies the time (UTC) when the security group rule is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the security group rule is updated. Format: yyyy-MM-ddTHH:mm:ss
