This parameter MUST always be included in Inform messages.

Enables and disables the CPE’s support for CWMP. false means that CWMP support in the CPE is disabled, in which case the device MUST NOT send any Inform messages to the ACS or accept any Connection Request notifications from the ACS. true means that CWMP support on the CPE is enabled. The subscriber can re-enable the CPE’s CWMP support either by performing a factory reset or by using a LAN-side protocol to change the value of this parameter back to true.

The factory default value MUST be true.

Password used to authenticate the CPE when making a connection to the ACS using the CPE WAN Management Protocol. This password is used only for HTTP-based authentication of the CPE. Note that on a factory reset of the CPE, the value of this parameter might be reset to its factory value. If an ACS modifies the value of this parameter, it SHOULD be prepared to accommodate the situation that the original value is restored as the result of a factory reset.

When read, this parameter returns an empty string, regardless of the actual value.

ParameterKey provides the ACS a reliable and extensible means to track changes made by the ACS. The value of ParameterKey MUST be equal to the value of the ParameterKey argument from the most recent successful SetParameterValues, AddObject, or DeleteObject method call from the ACS. The CPE MUST set ParameterKey to the value specified in the corresponding method arguments if and only if the method completes successfully and no fault response is generated. If a method call does not complete successfully (implying that the changes requested in the method did not take effect), the value of ParameterKey MUST NOT be modified. The CPE MUST only modify the value of ParameterKey as a result of SetParameterValues, AddObject, DeleteObject, or due to a factory reset. On factory reset, the value of ParameterKey MUST be set to an empty string.

This parameter MUST always be included in Inform messages.

Active Notification requests for this parameter MAY be denied.

Note: If the host portion of the URL is a literal IPv6 address then it MUST be enclosed in square brackets (see [Section 3.2.2/RFC3986]).

This parameter MUST always be included in Inform messages.

Active Notification MUST by default be enabled for this parameter.

Password used to authenticate an ACS making a Connection Request to the CPE.

When read, this parameter returns an empty string, regardless of the actual value.

Address and port to which an ACS MAY send a UDP Connection Request to the CPE (see [Annex G/TR-069a2]). This parameter is represented in the form of an Authority element as defined in [RFC3986]. The value MUST be in one of the following two forms:

host:port

host

• When STUNEnable is true, the host and port portions of this parameter MUST represent the public address and port corresponding to the NAT binding through which the ACS can send UDP Connection Request messages (once this information is learned by the CPE through the use of STUN).
• When STUNEnable is false, the host and port portions of the URL MUST represent the local IP address and port on which the CPE is listening for UDP Connection Request messages. The second form of this parameter MAY be used only if the port value is equal to 80.

Note: If the host portion of the URL is a literal IPv6 address then it MUST be enclosed in square brackets (see [Section 3.2.2/RFC3986]).

• InstanceNumber
• InstanceAlias This parameter is REQUIRED for any CPE supporting Alias-Based Addressing.

The factory default value MUST be InstanceNumber.

Enable or disable the Auto-Create Instance Mechanism. When AliasBasedAddressing is true, AutoCreateInstances indicates whether or not the CPE will automatically create instances while processing a SetParameterValues RPC (as defined in [A.3.2.1/TR-069a4]). *A true value indicates that the CPE will perform auto-creation of instances when the Alias-Based Addressing Mechanism is used in SetParameterValues RPC. *A false value indicates that the CPE will not create new object instances. Instead, it will reject the setting of parameters in unrecognized instances and respond with a fault code. This parameter is REQUIRED for any CPE supporting Alias-Based Addressing.

The factory default value MUST be false.

The value MUST be the value of the XMPP.Connection.{i}.JabberID contained in the XMPP.Connection instance referenced by the ConnReqXMPPConnection parameter. If the ConnReqXMPPConnection parameter is empty or the XMPP.Connection instance being reference is disabled, then this value will be empty. If the XMPP.Connection instance being referenced by the ConnReqXMPPConnection parameter is lost (XMPP.Connection.{i}.Status parameter changes from Enabled to some other value), then the value of this parameter MUST remain unchanged until the connection can be reestablished and a new XMPP.Connection.{i}.JabberID can be established. If the new XMPP.Connection.{i}.JabberID is identical to the existing value, then the value of this parameter MUST NOT be altered and a VALUE CHANGE event MUST NOT be generated.

Active Notification MUST by default be enabled for this parameter.

The current operational state of the bonding group (see [Section 4.2.2/TR-181i2]). Enumeration of:

• Up
• Down
• Unknown
• Dormant
• NotPresent
• LowerLayerDown
• Error (OPTIONAL) When Enable is false then Status SHOULD normally be Down (or NotPresent or Error if there is a fault condition on the interface). When Enable is changed to true then Status SHOULD change to Up if and only if the interface is able to transmit and receive network traffic; it SHOULD change to Dormant if and only if the interface is operable but is waiting for external actions before it can transmit and receive network traffic (and subsequently change to Up if still operable when the expected actions have completed); it SHOULD change to LowerLayerDown if and only if the interface is prevented from entering the Up state because one or more of the interfaces beneath it is down; it SHOULD remain in the Error state if there is an error or other fault condition detected on the interface; it SHOULD remain in the NotPresent state if the interface has missing (typically hardware) components; it SHOULD change to Unknown if the state of the interface can not be determined for some reason. This parameter is based on ifOperStatus from [RFC2863].
