Hey Guys!

I’m trying to add pppoe information in Listen Devices, but I’m having difficulties because different CPEs have different parameters, and I’d like to find a way to add them all, I found some provided on VirtualParameters, but when I tried, the page was blank. Can someone help me and see if there’s something wrong…

Virtual Paramater  
pppUsername  
let result = ‘’;

if (declare(“Tags.Bridged”, {value: 1}).value !== undefined) {  
log(‘CPE is bridged, setting PPPoE username to null’);  
} else if (“value” in args[1]) {  
result = args[1].value[0];  
} else {  
let keys = [  
‘InternetGatewayDevice.WANDevice._.WANConnectionDevice._.WANPPPConnection._.Username’,  
'Device.PPP.Interface._.Username’  
];

```
result = getParameterValue(keys);

```

}

return {writable: true, value: [result, “xsd:string”]};

function getParameterValue(keys) {  
for (let key of keys) {  
let d = declare(key, {path: Date.now() - (120 \* 1000), value: Date.now()});

```
    for (let item of d) {
        if (item.value && item.value[0]) {
            return item.value[0];
        }
    }
}

return '';

```

}

Provisons

declare(‘VirtualParameters.pppUsername’, {path: Date.now(), value: Date.now()});

Editing index page

- label: “‘PPPoE’”  
parameter: VirtualParameters.pppUsername

Your declare is wrong.

```auto
declare('VirtualParameters.pppUsername', {value: Date.now()}, {value: 'the_user_name'});

```

And how did you try? You need to include code and logs.
