Enumeration of: {{enum}} This object describes the parameters necessary to administer the store-and-forward (SAF) handling policies applied to requests to access remotely hosted resources. Policies are described by instances of {{object}}. Which instances of {{object}} are used by the SCL is determined by the {{param|PolicyScope}} parameter. Section 9.3.1.5 of the M2M Functional Architecture {{bibref|ETSIM2MFA}} and Section 10.3.1.2.2 of the M2M mIa, dIa and mId Interfaces {{bibref|ETSIM2MInterfaces}} describe the behavior for SAF processing. There is at most one {{object}} instance with the {{param|PolicyScope}} containing a specific application id (APP-ID) URI value within the list. There is exactly one {{object}} instance with a {{param|PolicyScope}} value of "default". Administratively enables or disables this instance. {{datatype|expand}} The parameter defines the scope of the policies contained in this instance of a {{object|#.SAFPolicySet}}. The parameter value is: *a list of unordered set of URIs {{bibref|RFC3986}} that represents an M2M application id (APP-ID) *the value of "default" *{{empty}} When this parameter is set to a list of application id (APP-ID) URIs {{bibref|RFC3986}}, the scope indicates that the policies are applicable to requests coming from any specific application on that list. When this parameter is set to a string with the value "default", the scope indicates that the policies are the default policies for this {{object|##.SCL}} instance. When this parameter is set to {{empty}}, the value represents an unknown {{object|#.SAFPolicySet}} and the {{object|#.SAFPolicySet}} is not to be used. {{numentries}} This table contains the SAF-handling policies which are controlled by the Access Network Provider(s). {{keys}} Administratively enables or disables this instance. {{datatype|expand}} This parameter is the name of the access network provider and used to determine for which access network the policies defined in the {{object|#.ANPPolicy}} table will apply. {{numentries}} {{numentries}} This table contains a list of block periods for a {{object|##.ANPPolicy}}.

Administratively enables or disables this instance. {{datatype|expand}} Number of consecutively failed access attempts for which the {{param|BlockDuration}} will be used to block the next access attempt. The SCL will apply the {{object}} entry with the largest number of consecutive failed attempts that is smaller or equal to the actual number of consecutive failed attempts. The duration, in {{units}}, to which to block further access attempts. This table contains the Request Category (RCAT) policy items for defining when it is appropriate to use the access network for processing requests. Administratively enables or disables this instance. {{datatype|expand}} An RCAT is a string that represents a request category used for policy enforcement. {{numentries}} This table contains the schedules that define when it is appropriate to use the access network for processing requests for the specified value of the {{param|#.RCAT}}. The combination of all instances of the {{object|AbsTimeSpan}} along with the {{param|Schedules}} parameter makes up the complete schedule for this instance of a {{object}}. The {{param|Schedules}} parameter defines a recurrence of the schedule. If instances of {{object|AbsTimeSpan}} exist, these instances places constraints on the schedule recurrence. If the value of the {{param|Schedules}} parameter is {{empty}}, at least one enabled instance of {{object|AbsTimeSpan}} MUST exist. Processing behavior for the use of RCAT Schedules is defined in section 10.3.1.2.2 of the M2M mIa, dIa and mId Interfaces {{bibref|ETSIM2MInterfaces}} document. Administratively enables or disables this instance. {{datatype|expand}} The list is a set of schedule strings. A schedule string is formatted according to the date and time fields defined CRONTAB input file definition in {{bibref|POSIXBase}}. The {{param}} parameter is used to set the recurrence of the schedule. The timezone used for this parameter is dependent upon the existence of instances of {{object|AbsTimeSpan}} for this {{object}}. If instances of {{object|AbsTimeSpan}} exist, then the timezone of the {{object|AbsTimeSpan}} is used otherwise the UTC timezone is used for this {{param}} parameter. Note the command field is not used in this definition and any whitespace or comma characters within a Schedule string MUST be escaped using percent as defined in {{bibref|TR-106|section 3.2.3}} Example of CRONTAB string: *"* 0-6 * * 1-5" would mean every minute for the period from 0:00h to 6:00h (inclusive) on any week day (Monday through Friday) and would be represented as "*%200-6%20*%20*%201-5" *"*/15 22-23,0-4 * * 1-5" would mean every 15 minutes for the period from 22:00h to 04:00h on any week day (Monday through Friday) and would be represented as "*/15%2022-23%2C0-4%20*%20*%201-5" {{numentries}} This object defines an instance of a time span used for determining an RCAT schedule. An instance of the {{object}} represents the time span in which the schedule recurrence defined in {{param|#.Schedules}} is constrained. {{object}} instances with unknown values for the {{param|StartTime}} or {{param|EndTime}} are ignored. All instances of the {{object}} within this {{object|##.Schedule}} MUST utilize the same time zone. Administratively enables or disables this instance. {{datatype|expand}} Date and time that represents the start of the time span. The value 0001-01-01T00:00:00Z represents an unknown value. The device MUST reject requests to set the {{param}} value greater than the {{param|EndTime}} value. Date and time that represents the end of the time span. The value 9999-12-31T23:59:59Z represents an infinite time span from the start time. The value 0001-01-01T00:00:00Z represents an unknown value. The device MUST reject requests to set the {{param}} value less than or equal the {{param|StartTime}} value. This object maintains the SAF handling policies' properties that are controlled by the M2M service provider for a request. The default RCAT value to use for requests to remotely hosted resources during SAF-handling when no RCAT value was specified in the request. {{numentries}} This object maintains a list of properties to be used for forwarding requests with a specified {{param|RCAT}}. Processing behavior for the use of M2M Service Provider policies is defined in section 10.3.1.2.2.1 of the M2M mIa, dIa and mId Interfaces {{bibref|ETSIM2MInterfaces}} document. Administratively enables or disables this instance. {{datatype|expand}} An RCAT is a string that represents a request category used for policy enforcement. The tolerable duration, in {{units}}, that a request of the given RCAT category can be pending in SAF handling when a request from an M2M Application does not specify a tolerable delay. A value of -1 represents an infinite duration. The threshold of maximum number of pending requests permitted to be held for a specified RCAT. A value of 0 indicates that the request should be transmitted immediately. This parameter defines the maximum size of the request queue for pending requests permitted to be held for a specified RCAT. The format of the string is an integer with an appended memory unit (B - Bytes, K - 1024 Bytes, M - 1048576 Bytes, G -1073741824, T - 1099511627776 Bytes). When the value is {{empty}} the memory threshold criteria for the associated RCATList will be ignored in SAF handling. {{pattern}} {{empty}} The list is a prioritized set of Access Networks where the preference of using an Access Network is based on order of the list items with the lowest order list item as the most preferred Access Network.

URI {{bibref|RFC3986}} that represents the identifier of the instance. Devices (D' and d) that connect to an SCL are said to be "attached devices" and are organized by M2M Area Networks within the {{object|##.SCL}} instance. The {{param}} is an implementation-chosen string that indicates the type of M2M Area Network. {{list}} {{reference}} The list represents the M2M Devices (D', d) that are attached to this {{object|##.SCL}} instance that are within this {{object}} instance. The list does not contain an instance for this CPE. {{numentries}} This object contains an instance of a property extension (name value pair) for this {{object|##.AreaNwkInstance}} instance. For example, if the {{param|#.AreaNwkType}} is ZigBee the {{object|##.AreaNwkInstance}} will contain ZigBee specific parameters that have not been modeled for the M2M Area network. At a minimum, a property instance MUST exist that defines an attribute that describes the IP layer address type (e.g., IPv4, IPv6, non-IP) of this M2M Area Network.

A M2M Device is associated with an instance of a {{object|#.AreaNwkInstance}}. This table contains parameters and information of the M2M Device related to each {{object|#.AreaNwkInstance}} instance. Instances of this table are created and deleted by the CPE. The ACS MAY modify the writeable parameters of this object instance but it is possible that the value set by the ACS is not retained between reboots of the M2M Device. {{reference}} {{list}} {{reference|the {{object|.Hosts.Host}} table entry that represents an active or inactive M2M Device}} {{list}} {{reference}} References all the {{object|.Hosts.Host}} table entries, whether active or inactive, that represent the reachable neighbors of this M2M Device (D' or d). The list is an unordered set of URIs {{bibref|RFC3986}}. A list item is an URI string that represents an application id (APP-ID) for the M2M D'A applications residing on the M2M Device for the associated {{object|#.AreaNwkInstance}}. Table B.58 of the M2M Functional Architecture {{bibref|ETSIM2MFA}} describes this parameter. The interval, in {{units}}, between sleep periods for the device.
