page_info	PageInfo object	Definition: Pagination information. Range: None

**Table 4** SecurityGroupRule
Parameter	Type	Description
id	String	Definition: ID of a security group rule. After a security group rule is created, a security group rule ID is generated, which uniquely identifies the security group rule. Range: The value is in UUID format with hyphens (-).
description	String	Definition: Description of a security group rule. Range: The value can contain no more than 255 characters and cannot contain angle brackets (< or >).

ethertype	String	Definition: IP address version of a security group rule. Range: IPv4 IPv6
multiport	String	Definition: Port range of a security group rule. Range: The value can be a single port (80), a port range (1-30), or inconsecutive ports separated by commas (22,3389,80).
action	String	Definition: Action of a security group rule. Range: allow deny
priority	Integer	Definition: Priority of a security group rule. Range: The value is from 1 to 100. The value 1 indicates the highest priority.
remote_group_id	String	Definition: ID of the remote security group of a security group rule. If the action of the rule is allow, the traffic from the remote security group is allowed. If the action of the rule is deny, the traffic from the remote security group is denied. Range: ID of an existing security group.
remote_ip_prefix	String	Definition: Remote IP address of a security group rule. If direction is set to egress, the IP address is the outbound destination and will be accessed by instances in the security group. If direction is set to ingress, the IP address is the inbound source and will access the instances in the security group. Range: CIDR notation format. If an IP address is transferred in the request, the IP address is automatically formatted with /32 as the subnet mask, for example, 192.168.21.45/32.
remote_address_group_id	String	Definition: ID of the remote IP address group of a security group rule. Range: ID of an existing IP address group.
created_at	String	Definition: Time when a security group rule was created. Range: UTC time in the format of yyyy-MM-ddTHH:mm:ssZ
updated_at	String	Definition: Time when a security group rule was updated. Range: UTC time in the format of yyyy-MM-ddTHH:mm:ssZ
project_id	String	Definition: ID of the project that a security group rule belongs to. Range: None
enabled	Boolean	Definition: Whether to enable a security group rule. Range: true: The security group rule is enabled. false: The security group rule is disabled.

**Table 5** PageInfo
Parameter	Type	Description
previous_marker	String	Definition: The first record on the current page. Range: N/A
current_count	Integer	Definition: Total number of resources on the current page. Range: N/A
next_marker	String	Definition: The last record on the current page. The next_marker field does not exist if the page is the last one. Range: N/A
