How to use DUStates

1

Hi all,

Looking for some input and assistance on how to use TR-157 with GenieACS. It seems it has been implemented in the ChangeDUStates branch in Github. I have deployed an instance of GenieACS with these changed merged however I’m unsure how to actually get them to work.

I’ve attempted the following in a provision which I can confirm is executing based on the logs however there are no changes to the device parameters nor any RPCs made to/from the device.

        log(`We can install a container`);

        declare('DUStates.0.URL', {value: now}, {value: 'https://example.com/container.ipk'});
        declare('DUStates.0.UUID', {value: now}, {value: '68bef7b0-8822-4738-b70b-99c03b613d7f'});
        declare('DUStates.0.OperationType', {value: now}, {value: 'install'});
        declare('DUStates.0.ChangeDUState', { value: now }, { value: now });

        commit();

        log(`We have attempted to install the container on the device`);

Any assistance on how to use this feature is greatly appreciated.

I’m not familiar with TR-157. But does the object DUStates.0 currently exist? If not, then you need to add the instance like so:

log(`We can install a container`);

declare('DUStates.[URL:https://example.com/container.ipk,UUID68bef7b0-8822-4738-b70b-99c03b613d7f,OperationType:install,ChangeDUState:' + Date.now() + ']', {path: 1}, {path: 1});

log(`We have attempted to install the container on the device`);

An explicit commit() is almost always not necessary.

Hi, I’d like to dig out this old topic.
I’m trying to install an app using a container on a WNC Freedom board (prplOS reference platform). OS shell method using ba-cli (bus-agnostic cli) is working fine, and now I’m trying to trigger it via CWMP.

Following the previous comment, I created a provision:

declare("Tags.DUInstall", null, {value: true});

declare('DUStates.[URL:<URL>,UUID:<UUID>,OperationType:install,ChangeDUState:' + Date.now() + ']', {path: 1}, {path: 1});

and scheduled it for a “2 PERIODIC” event code.

The tag is added in the device view, but GenieACS is not sending ChangeDUState RPC to the CPE. The session ends after InformResponse from ACS (I don’t have any other RPCs scheduled for Inform event code).

I’d appreciate guidance on how to use the ChangeDUState with the Install*, Update* and UninstallOpStruct.
