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.

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”.

The value of the STUN Password to be used in computing the MESSAGE-INTEGRITY attribute to be used in Binding Requests (only if message integrity has been requested by the STUN server).

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

Indicates whether or not the Alias-Based Addressing Mechanism is supported. A true value indicates that the CPE supports the Alias-Based Addressing Mechanism, as defined in [Section 3.6.1/TR-069a4] and described in [Appendix II/TR-069a4].

This parameter MUST always be included in Inform messages.

If the CPE supports the Alias-based Addressing feature as defined in [Section 3.6.1/TR-069] and described in [Appendix II/TR-069], the following mandatory constraints MUST be enforced:

• Its value MUST NOT be empty.
• Its value MUST start with a letter.
• If its value is not assigned by the ACS, it MUST start with a “cpe-” prefix.
• The CPE MUST NOT change the parameter value. This parameter can only be modified if StaticRoute is true

The Agent MUST choose an initial value that doesn’t conflict with any existing entries.

Active Notification requests for this parameter MAY be denied.

A Forwarding table entry for which DestIPAddress and DestSubnetMask are both an empty string or “0.0.0.0” is a default route.

[IPAddress] Destination subnet mask. An empty string or a value of “0.0.0.0” indicates no destination subnet mask is specified.

If a destination subnet mask is specified, the DestSubnetMask is ANDed with the destination address before comparing with the DestIPAddress. Otherwise, the full destination address is used as is. A Forwarding table entry for which DestIPAddress and DestSubnetMask are both an empty string or “0.0.0.0” is a default route.

[IPAddress] Source subnet mask. An empty string or a value of “0.0.0.0” indicates no source subnet mask is specified.

If a source subnet mask is specified, the SourceSubnetMask is ANDed with the source address before comparing with the SourceIPAddress. Otherwise, the full source address is used as is.

If the CPE supports TR-064 (LAN-side DSL CPE Configuration Protocol), this parameter is to be used as the dslf-config password (as defined in TR-064). If the CPE has a user interface with password protection enabled, this parameter is also to be used as the user password for password-protected operations. However, this parameter MUST NOT be used to set the user password if the parameter InternetGatewayDevice.UserInterface.PasswordUserSelectable is true.

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

Indicates availability of diagnostic data. Enumeration of:

• None (READONLY)
• Requested
• Complete (READONLY)
• Error_CannotResolveHostName (READONLY)
• Error_Internal (READONLY)
• Error_Other (READONLY) If the ACS sets the value of this parameter to Requested, the CPE MUST initiate the corresponding diagnostic test. When writing, the only allowed value is Requested. To ensure the use of the proper test parameters (the writable parameters in this object), the test parameters MUST be set either prior to or at the same time as (in the same SetParameterValues) setting the DiagnosticsState to Requested. When requested, the CPE SHOULD wait until after completion of the communication session with the ACS before starting the diagnostic. When the test is completed, the value of this parameter MUST be either Complete (if the test completed successfully), or one of the Error values listed above. If the value of this parameter is anything other than Complete, the values of the results parameters for this test are indeterminate. When the diagnostic initiated by the ACS is completed (successfully or not), the CPE MUST establish a new connection to the ACS to allow the ACS to view the results, indicating the Event code 8 DIAGNOSTICS COMPLETE in the Inform message. After the diagnostic is complete, the value of all result parameters (all read-only parameters in this object) MUST be retained by the CPE until either this diagnostic is run again, or the CPE reboots. After a reboot, if the CPE has not retained the result parameters from the most recent test, it MUST set the value of this parameter to None. Modifying any of the writable parameters in this object except for this one MUST result in the value of this parameter being set to None. While the test is in progress, modifying any of the writable parameters in this object except for this one MUST result in the test being terminated and the value of this parameter being set to None. While the test is in progress, setting this parameter to Requested (and possibly modifying other writable parameters in this object) MUST result in the test being terminated and then restarted using the current values of the test parameters.

Active Notification requests for this parameter MAY be denied.

[Alias] A non-volatile handle used to reference this instance. Alias provides a mechanism for an ACS to label this instance for future reference.

If the CPE supports the Alias-based Addressing feature as defined in [Section 3.6.1/TR-069] and described in [Appendix II/TR-069], the following mandatory constraints MUST be enforced:

• Its value MUST NOT be empty.
• Its value MUST start with a letter.
• If its value is not assigned by the ACS, it MUST start with a “cpe-” prefix.
• The CPE MUST NOT change the parameter value.

The Agent MUST choose an initial value that doesn’t conflict with any existing entries.

Active Notification requests for this parameter MAY be denied.

[IPAddress] Specifies first address in the pool to be assigned by the DHCP server on the LAN interface.

This parameter MUST have a valid value before the DHCP server can be enabled.

[IPAddress] Specifies last address in the pool to be assigned by the DHCP server on the LAN interface.

This parameter MUST have a valid value before the DHCP server can be enabled.

[IPAddress] Specifies the client’s network subnet mask.

This parameter MUST have a valid value before the DHCP server can be enabled.

Controls use of addresses from the associated WAN connection. Enumeration of:

• Normal
• UseAllocatedSubnet (DEPRECATED)
• Passthrough If Normal, the address pool is directly configured by the ACS. If {{enum: reference to deprecated enumeration InternetGatewayDevice.LANDevice.{i}.LANHostConfigManagement.UseAllocatedWAN.UseAllocatedSubnet}}, behavior is the same as for Passthrough with an empty PassthroughMACAddress. For this reason, {{enum: reference to deprecated enumeration InternetGatewayDevice.LANDevice.{i}.LANHostConfigManagement.UseAllocatedWAN.UseAllocatedSubnet}} is DEPRECATED. If Passthrough, and PassthroughMACAddress is an empty string, the configured values of the MinAddress, MaxAddress, SubnetMask and DNSServers parameters are ignored. The corresponding address pool values are instead taken from the WAN connection specified by AssociatedConnection. If Passthrough, and PassthroughMACAddress is not an empty string, the LAN Host identified by PassthroughMACAddress is given a WAN IP address from the WAN connection specified by AssociatedConnection. Other LAN Hosts are treated as for Normal. Use of PassthroughMACAddress does not cover the case where more than one LAN Host is to be given a WAN IP address. This can be achieved by using a DHCP conditional serving pool.

[Alias] A non-volatile handle used to reference this instance. Alias provides a mechanism for an ACS to label this instance for future reference.

If the CPE supports the Alias-based Addressing feature as defined in [Section 3.6.1/TR-069] and described in [Appendix II/TR-069], the following mandatory constraints MUST be enforced:

For example, only basic 802.11 might be supported by one virtual AP, and only WPA might be supported by another virtual AP. A value of None means that no capabilities are currently enabled on the access point and that no stations will be able to associate with it. Enumeration of:

• None

The ACS SHOULD NOT set the passphrase and also set the WEP keys directly (the result of doing this is undefined). This MUST either be a valid key length divided by 8, in which case each byte contributes 8 bits to the key, or else MUST consist of Hex digits and be a valid key length divided by 4, in which case each byte contributes 4 bits to the key. Note: If a passphrase is used, all four WEP keys will be the same.
