I thought I had already done this at some point, where it only lists them all if there’s less than a certain number… oO

Subject: Re: [Observium] Same Subnet devices

I can appreciate the argument that the list is long when there are a large number of neighbouring devices on that subnet. Even with a /24 that could potentially be a large count.

Perhaps showing just 5-10 of them with a "more..." button to expand the list might be a good way to improve it. ?

I guess it depends on your use case. In most ISP networks and even in my large enterprise network, there is zero subnet overlap...

It works, but I think it is  uncomfortable. I should exclude ALL networks.
It should be better give the option to activate subnet association, rather than configure undesired networks.
In large environment, like our case, it is also useless...

Hi,

The subnets need to match exactly, (unfortunately?) - you'll have to add 172.31.255.0/24 to the list to make these disappear.

Hi Tom
Following the examples in defaults.inc.php file, I've added the following line in config.php file:

$config['ignore_common_subnet'][] = '172.31.0.0/16';

but in device's port page I still see all 172.31.255.x networks belonging to other devices (it contains about 70 devices) on the right:

What do you mean disables specified networks? That setting is only used on that specific page to not display those links on the right.

Hi Tom.
Ok, I tried the suggested option, but it completely disables specified networks.
I want only "disable" the right list of subnet in device's port page.

Hi Arrigo,

You can add network ranges to be ignored to the $config['ignore_common_subnet'] array in config.php.

Hi All.
Is there a way to disable same subnet devices shown in port list:

Since we have lots of devices with identical LAN network, list on the right of the page can be very long (and useless, btw ...).

Thanks,
Arrigo.
