Request Parameters

Table 1 Request parameter

Name

Mandatory

Type

Description

security_group_rule

Yes

security_group_rule object

Specifies the security group rule objects. For details, see Table 2.

Table 2 Description of the security_group_rule field

Name

Mandatory

Type

Description

security_group_id

Yes

String

Specifies the security group ID.

description

No

String

  • Provides supplementary information about the security group rule.
  • The value can contain no more than 255 characters, including letters and digits.

direction

Yes

String

  • Access control direction specified in a security group rule.
  • The value can be:
    • egress
    • ingress

ethertype

No

String

  • Specifies the IP protocol version.
  • The value can be IPv4 or IPv6.
  • If you do not set this parameter, IPv4 is used by default.

protocol

No

String

  • Specifies the protocol type.
  • The value can be icmp, tcp, udp, or an IP protocol number (0 to 255, for example, 47 for GRE)
  • If the parameter is left blank, all protocols are supported.

port_range_min

No

Integer

  • Specifies the start port number.
  • The value ranges from 1 to 65535.
  • The value cannot be greater than the port_range_max value. An empty value indicates all ports. If the protocol is icmp, the value range is shown in ICMP-Port Range Relationship Table.

port_range_max

No

Integer

  • Specifies the end port number.
  • The value ranges from 1 to 65535.
  • If the protocol is not icmp, the value cannot be smaller than the port_range_min value. An empty value indicates all ports. If the protocol is icmp, the value range is shown in ICMP-Port Range Relationship Table.

remote_ip_prefix

No

String

  • Specifies the remote IP address. If the access control direction is set to egress, the parameter specifies the source IP address. If the access control direction is set to ingress, the parameter specifies the destination IP address.
  • The value can be in the CIDR format or IP addresses.
  • The parameter is mutually exclusive with parameter remote_group_id.

remote_group_id

No

String

  • Specifies the ID of the peer security group.
  • This parameter is mutually exclusive with parameter remote_ip_prefix.

Example Request

  • Create an inbound rule in the security group whose ID is a7734e61-b545-452d-a3cd-0189cbd9747a.
