Netgear genie reboot router8/15/2023 Bootstrap – when device contacts the server for the first time, the server URL changed, or the device settings were reset to default.There are certain events that will trigger the provisioning session. This stage (and the whole provisioning session) is terminated by an empty HTTP-response from the ACS indicating that no more orders are pending. Multiple orders may be transmitted one-by-one. This will subsequently be followed by an HTTP-request containing a CWMP-response for the previous CWMP-request. The HTTP-response for the empty HTTP-request by the device will contain a CWMP-request from the ACS. In the third stage the roles change on the CWMP level. This stage is finalized by transmission of empty HTTP-request to the ACS. Even though the protocol defines multiple methods that may be invoked by the device on the ACS, only one is commonly found - TransferComplete - which is used to inform the ACS of the completion of a file transfer initiated by a previously issued Download or Upload request. In the second stage, orders are transmitted from the device to the ACS. The following description assumes the value is false. If the value is false the initialization stage is followed by the transmission of device requests, otherwise ACS orders are transmitted first. The order of the next two stages depends on the value of the flag HoldRequests. That concludes the session initialization stage. Its reception and readiness of the server for the session is indicated by an InformResponse message. The session is always started by the device (CPE) and begins with the transmission of an Inform message. Provisioning session Īll communications and operations are performed in the scope of the provisioning session. Additionally, if authentication is required for security reasons, data such as the username and the password needs to be provided. These include the URL of the server the device wants to connect to and the interval at which the device will initiate the provisioning session ( PeriodicInformInterval). In order for the device to connect to the server, it needs to have certain parameters configured first. This essentially means that control over the flow of the provisioning session is the sole responsibility of the device. At this level (HTTP), the CPE acts as client and ACS as HTTP server. Orders sent between the device (CPE) and auto configuration server (ACS) are transported over HTTP (or more frequently HTTPS). Other technical initiatives, such as the Home Gateway Initiative (HGI), Digital Video Broadcasting (DVB) and WiMAX Forum endorsed CWMP as the protocol for remote management of residential networking devices and terminals.Ĭommunication Transport ĬWMP is a text based protocol. The protocol addresses the growing number of different Internet access devices such as modems, routers, gateways, as well as end-user devices which connect to the Internet, such as set-top boxes, and VoIP-phones. The CPE WAN Management Protocol is a bidirectional SOAP- and HTTP-based protocol, and provides the communication between a CPE and auto configuration servers (ACS). TR-069 uses the CPE WAN Management Protocol ( CWMP) which provides support functions for auto-configuration, software or firmware image management, software module management, status and performance managements, and diagnostics. Technical Report 069 ( TR-069) is a technical specification of the Broadband Forum that defines an application layer protocol for remote management and provisioning of customer-premises equipment (CPE) connected to an Internet Protocol (IP) network.
