LLDP? Am I missing something or will HA just not do it?

I use managed switches in my home and I would love to get LLDP working so that my switches are aware of the machine by something more than mac address and arp entries.

Is there any support for LLDP?

Did you ever find a good solution for the managed HAOS versions of home assistant to get lldp (or cdp)?

Nope, it appears that it is and will remain an unsupported protocol. Heck, my Unraid servers can speak LLDP even.

In all my years using Home Assistant and browsing these forums, this is the first time I saw anyone asking for Link Layer Discovery Protocol support.

Unless you write an integration yourself, I would bet on, “No”.

If I had the knowledge and ability, I likely would do just that. But, I do not.

Have you ever used LLDP and SNMP within a network? In combination they allow for mapping and troubleshooting advantages that usually do not exist. In the enterprise environment, almost everything except basic workstations talk LLDP. Switches, routers, firewalls, phones, servers, access points and many linux client systems, even Windows 10/11 are both able to.

SNMP. A loooong time ago.

Just curious, what are you trying to do with LLDP? I am in the process of upgrading my Verizon router to a tp-link managed system. (Primarily because my Verizon router can’t reliably handle more than 60 simultaneous connections). I assume that the tp-link Onada control software discovers the connected devices using LLDP, but I can’t imagine a scenario where I would ever need that level of granularity.

I use Omada for my wireless with Omada controller on my Unraid primary server. My switches are HPE and Aruba and my router/firewall is PFSense.

I use a script running SNMP to ask interfaces on my switches what the device connected to each port is, allows me to see if any patch cables have been moved. Only run the script about once per month to maintain a baseline view. I would love it if my instance of HA could identify itself to the network by something other than mac address, that is all.

As far as Omada using LLDP, I am not sure that is how they discover… my APs do not have it enabled by default and I have not been able to find where to enable it. Really annoying!

I’ve created a simple home assistant addon to add LLDP support.
