Hello, does anyone know how to filter different patch parameters? Example, I want to search for MACs of connected devices but there are more than one, parameter: InternetGatewayDevice.LANDevice.1.Hosts.Host. (Here is the device number) .MACAddress.

Hi, in order to get the IP Address of a host with MAC aa:bb:cc:01:02:03, you can use something like this:  
declare(‘InternetGatewayDevice.LANDevice.1.Hosts.Host.[MACAddress:“aa:bb:cc:01:02:03”].IPAddress’, {value: Date.now() }).value

I tried to make sense of what you asked and I came up with the above answer … If you want to filter devices in the UI based on the MAC address of the hosts connected, this can be done with virtual parameters.

Just add a virtual parameter with the name “hostsmacs” with this code:

```
let macs=[];
let d=declare("InternetGatewayDevice.LANDevice.1.Hosts.Host.*", {path: Date.now()});
for (let i of d) {
    macs.push(declare(i.path+'.MACAddress', {value: Date.now()}).value[0]);
}
return {writable: false, value: [macs.join(), "xsd:string"]};

```

And add the following filter:

```
- label: "'Hosts MAC'"
  parameter: VirtualParameters.hostsmacs
  type: "'string'"

```

After reload you will be able to search devices by “Hosts MAC: %aa:bb:cc:01:02%” … BUT, for this to work as expected you must refresh this virtual parameter first (and also periodically).

first thanks for the help, it worked but the value is repeating the first mac.

please replace d.path with i.path … I fixed my answer now

When there is more than one manufacturer, the variable must change so that I can find the PPPoE in more than one parameter. I used the example but it returns an error →   
name:TypeError  
message: Cannot read property ‘0’ of undefined  
stack: |-  
TypeError: Cannot read property ‘0’ of undefined  
until PPPoE: 5:89

I’m using the following filter:

let pppoe=[];  
let d=declare(“InternetGatewayDevice.WANDevice.1.WANConnectionDevice.\*”, {path: Date.now()});  
for (let i of d) {  
pppoe.push(declare(i.path+’.WANPPPConnection.1.Username’, {value: Date.now()}).value[0]);  
}  
return {writable: false, value: [pppoe.join(), “xsd:string”]};

Yes, you will receive this error if there is no WANPPPConnection on the WANConnectionDevice.\* or if the WANPPPConnection instance is different from 1. Try this instead:

```auto
let pppoe=[];
let d=declare(“InternetGatewayDevice.WANDevice.1.WANConnectionDevice.*.WANPPPConnection.*”, {path: Date.now()});
for (let i of d) {
   pppoe.push(declare(i.path+".Username", {value: Date.now()}).value[0]);
}
return {writable: false, value: [pppoe.join(), “xsd:string”]};
```

Hi Guys,

I have added the below code and add the virtual parameter under filter but when I search for a mac nothing returns, is there any issue with the code I am using or is there another step missing in this process? Thank you

let m = “00:00:00:00:00:00”;  
let d = declare(  
“Device.WANDevice._.WANConnectionDevice._.WANIPConnection._.MACAddress",  
{ value: Date.now() }  
);  
let igd = declare(  
"InternetGatewayDevice.WANDevice._.WANConnectionDevice._.WANPPPConnection._.MACAddress”,  
{ value: Date.now() }  
);

let wanIP = declare(  
“InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANIPConnection.1.MACAddress”,  
{ value: Date.now() }  
);

let lanHost = declare(  
“InternetGatewayDevice.LANDevice.1.Hosts.Host.1.MACAddress”,  
{ value: Date.now() }  
);

if (d.size) {  
for (let p of d) {  
if (p.value[0]) {  
m = p.value[0];  
break;  
}  
}  
} else if (igd.size) {  
for (let p of igd) {  
if (p.value[0]) {  
m = p.value[0];  
break;  
}  
}  
} else if (wanIP.size) {  
for (let p of wanIP) {  
if (p.value[0]) {  
m = p.value[0];  
break;  
}  
}  
} else if (lanHost.size) {  
for (let p of lanHost) {  
if (p.value[0]) {  
m = p.value[0];  
break;  
}  
}  
}

return { writable: false, value: [m, “xsd:string”] };
