hello, community.
I’m quite new to LibreNMS and I apologize if I’m missing something obvious.
running LibreNMS ver 24.2.
My question pertains to the discovery protocols (LLDP) for MikroTik (routerOS) switches.
Although the switch’s OS and other features were successfully identified, LLDP (neighbors) information is missing. This absence is noticeable on the device’s “Neighbors” page, in the network map, and in the output of the discovery CLI command.
I have included verbose output from the OS discovery and discovery protocols, along with the config validation output, for further clarity.
Any advice or tips would be greatly appreciated.
thanks
