Introduction.

TR-069 is a technical specification that defines an application layer protocol for remote management of end-user devices. It was published by the Broadband Forum and was entitled CPE WAN Management Protocol (CWMP). It provides the communication between CPE and Auto Configuration Servers (ACS). An ACS can manage a device, trouble shoot, configure, upgrade etc. TR-69 uses common web protocols such as HTTP, TCP-IP, SOAP, XML-RPCs to exchange information.

GenieACS Server and Client BPIR4 communication.

The CPE is responsible for establishing the session to the server. The CPE keeps sending HTTP POST requests during the session. The session is closed as soon as both CPE & GenieACS  have indicated that they have nothing more to send (response or new RPC).

 

GenieACS Server.

Ensure the GenieACS Server Setup is launched and running to establish the Client-Server communication

Test Procedure

Client BPIR4 set-up

Steps to be followed:

1) Flash the RDK-Broadband image where the Tr069 Protocol Agent is enabled.

tr69 status 
root@Filogic-GW:/lib/systemd/system# systemctl status CcspTr069PaSsp.service 
● CcspTr069PaSsp.service - CcspTr069PaSsp service
     Loaded: loaded (/lib/systemd/system/CcspTr069PaSsp.service; enabled; vendor preset: enabled)
     Active: active (running) since Thu 2022-04-28 17:43:08 UTC; 2 years 6 months ago
    Process: 3809 ExecStartPre=/bin/sh -c val=`syscfg get EnableTR69Binary`; if [ "$val" == "false" ]; then `systemctl stop CcspTr069PaSsp`; fi (code=exited, status=0/SUCCESS)
    Process: 3834 ExecStart=/usr/bin/CcspTr069PaSsp -subsys $Subsys (code=exited, status=0/SUCCESS)
   Main PID: 3856 (CcspTr069PaSsp)
      Tasks: 17 (limit: 4713)
     Memory: 9.2M
     CGroup: /system.slice/CcspTr069PaSsp.service
             └─ 3856 /usr/bin/CcspTr069PaSsp -subsys eRT.


2) Check for the CcspTr069PaSsp is active and listening to port 7547

3)Then, set the parameters for connecting CPE with ACS server.

Comments for acs server connectivity 
$  dmcli eRT setv Device.ManagementServer.EnableCWMP bool true

$  dmcli eRT setv Device.ManagementServer.URL string http://192.168.2.165:7547/
 
$  dmcli eRT setv Device.DeviceInfo.X_RDKCENTRAL-COM_Syndication.TR69CertLocation string "/etc/cacert.pem"

4) Following are the parameters needed to be checked for TR69.

Parameter Name

Expected Value

Device.ManagementServer.EnableCWMPtrue
Device.ManagementServer.URLACS Server URL:  http://192.168.2.165:7547/
Device.DeviceInfo.X_RDKCENTRAL-COM_Syndication.TR69CertLocation/etc/cacert.pem

5) Now, from the GenieACS Server try to fetch the Connected Devices details.

GenieACS Server Login & Initial check

1) Visit the GenieACS Server page

2) Click on "Devices" that displays the connected devices information and the device parameters available


3) Force Inform Parameters
