Omada switches spamming DNS requests
Hello,
This applies to all my Omada switches. Every 15 seconds, each switch sends out a DNS request to omada. It fills up my logs with unnecessary requests. I run my switches as standalone and I assume this has something to do with a controller. Am I missing a setting on how to stop this? Thanks

@NeilR_M Yeah that was the first place I looked. I found a post on Reddit that seems to indicate TP-Link is aware of it and it is related to controller discovery. Seems firmware engineers forgot to disable controller discovery in standalone mode. I hope it gets fixed because it's kind of ridiculous and is an easy fix.

You can disable it via the CLI using the command no omada discover.

@smithj33 Is Cloud-Based Controller Management Enabled? That would be in System -> Controller Settings on the SG2008P, for example.
That would be the first place I'd check.

@Ethan-TP I was really hoping that would work, but it didn't. The command is actually, "no controller discover", but after changing it, saving the config and rebooting the switch, all 3 of my switches are still sending out the requests every 15 seconds. Thanks for the suggestion though. If you find out anything else, please let me know.

Currently, the feature deactivation may not be fully implemented. We will completely disable this DNS request in the future. The project is already in our planned roadmap, but the exact timeline for implementation is still unknown.

@Ethan-TP Any updates on this issue? I have ten (10) EAP-610s, upgraded one to 1.6.0 firmware, and it's still sending 'omada' DNS queries every 15 seconds. Are there workarounds besides blocking the requests?

No changes or workarounds. What's frustrating is that this is an easy fix with a check box. I'm sure being on the verge of being banned in the US has them busy though.

@smithj33 I installed the Omada Controller locally in a Proxmox Linux container, adopted all the APs and the 'omada' DNS queries went away. FYI.

@boudin Good you got yours fixed. What's interesting is my APs have never sent those requests, using docker or bare metal controller, but all my switches do. I don't use the controller for my switches, only the APs. TP-Link forgot to turn off discovery when you disable controller support.
