Link types of LLDP are not supported

Hello everyone. I installed LibrenMS and added six devices. The LLDP protocol is enabled on the devices, and data is being sent from them without any problems. However, I can’t see the neighborhood map. The map tab shows a blank white page. When I look at the logs, I see the message [2025-09-08T09:55:59][ERROR] Link types of lldp are not supported.

Thank you in advance for your help.



I think You should use only $config['network_map_items'] = ['xdp']. Look at docs there are mention only two parameters “mac” and “xdp”

Thank you for your answer. When I configure the map to only xdp, I no longer receive the “LLDP/CDP not supported” error in log file. However, the map is blank again, and when I look at the browser console, I see the javascript error I’ve posted a picture of.

You are going to be so disappointed when it finally works… but I cannot reproduce this unfortunately so it would be hard for me to fix it. Someone who can reproduce it might be able to take a crack at fixing it.

(xdp is correct fyi)

The problem stems from this configuration in config.php.

$config[‘network_map_vis_options’] = ‘base’;

I noticed this and disabled it. I don’t receive any errors, nothing appears in the log, but the map page is still blank. Now I need to fix this.

Does the device have any neighbors (according to lldp)? Because if it does not, the map should be blank.
