ModifySecurityGroupRule - API Reference| Alibaba Cloud Documentation Center

Description

In the security group-related API documents, inbound traffic refers to the traffic that is sent by the source device and received at the destination device.

You can determine an inbound 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 inbound security group rule that controls access from a specified CIDR block: IpProtocol, PortRange, SourcePortRange (optional), NicType, Policy, DestCidrIp, and SourceCidrIp (optional).
Parameters used to specify an inbound security group rule that controls access from a specified security group: IpProtocol, PortRange, SourcePortRange (optional), NicType, Policy, DestCidrIp (optional), DestGroupOwnerAccount, and DestGroupId.

Request parameters


Parameter	Type	Required	Example	Description
Action	String	Yes	ModifySecurityGroupRule	The operation that you want to perform. Set the value to ModifySecurityGroupEgressRule.

PortRange	String	Yes	80/80	The range of destination ports relevant to the transport layer protocol. Valid values: When the IpProtocol parameter is set to tcp or udp, the port number range is 1 to 65535. Separate the start port and the end port with a forward slash (/). Example: 1/200. When the IpProtocol parameter is set to icmp, the port number range is -1/-1, which indicates all ports. When the IpProtocol parameter is set to gre, the port number range is -1/-1, which indicates all ports. When IpProtocol is set to all, the port number range is -1/-1, which indicates all ports.

If SourceCidrIp is specified, SourceGroupOwnerId is ignored.
SourceGroupOwnerAccount	String	No	EcsforCloud@Alibaba.com	The Alibaba Cloud account that manages the source security group when you set a security group rule across accounts. If both SourceGroupOwnerId and SourceGroupOwnerAccount are empty, access permissions are configured for another security group managed by your account. If SourceCidrIp is specified, SourceGroupOwnerAccount is ignored.
SourceCidrIp	String	No	10.0.0.0/8	The range of source IP addresses. CIDR blocks and IPv4 addresses are supported. This parameter is empty by default.

SourcePortRange	String	No	80/80	The range of source ports relevant to the transport layer protocol. Valid values: When the IpProtocol parameter is set to tcp or udp, the port number range is 1 to 65535. Separate the start port and the end port with a forward slash (/). Example: 1/200. When the IpProtocol parameter is set to icmp, the port number range is -1/-1, which indicates all ports. When the IpProtocol parameter is set to gre, the port number range is -1/-1, which indicates all ports. When IpProtocol is set to all, the port number range is -1/-1, which indicates all ports.
DestCidrIp	String	No	10.0.0.0/8	The range of destination IP addresses. CIDR blocks and IPv4 addresses are supported. This parameter is empty by default.
Ipv6DestCidrIp	String	No	2001:db8:1234:1a00::***	The range of destination IPv6 addresses. CIDR blocks and IPv6 addresses are supported. Note You can specify only the IP addresses of instances in VPCs. This parameter is empty by default.
Policy	String	No	accept	The access control policy. Valid values: accept: grants access. drop: denies access without returning a rejection response. Default value: accept.
Priority	String	No	1	The priority of the security group rule. Valid values: 1 to 100. Default: 1.
NicType	String	No	intranet	The NIC type of the rule when the security group is in the classic network. Valid values: internet intranet Default value: internet. The NicType parameter can be set to only intranet in the following cases: If the security group is in a VPC, this parameter is required and must be set to intranet. If DestGroupId is specified but DestCidrIp is not, NicType must be set to intranet.
ClientToken	String	No	123e4567-e89b-12d3-a456-426655440000	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests. The ClientToken value must contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.
Description	String	No	This is a new security group rule.	The description of the security group rule. The description must be 1 to 512 characters in length.
