What Is Firewall_Instance_Id?
Firewall_Instance_Id is a CFW instance ID. It is automatically generated by the system after CFW is created.
- By default, if fw_instance_Id is not specified, information about the first firewall under the account is returned. If fw_instance_Id is specified, information about the firewall with this fw_instance_Id is returned.
- If object_Id is specified, information about the firewall with this object_Id is returned by default. If both fw_instance_Id and object_Id are specified, the specified object_Id must belong to the specified firewall.
