The command that worked for me (SG2210P switch) was (over SSH):

 

Switch> enable

Switch# configure

Switch(config)# no controller discover

Switch(config)# end

Switch# copy running-config startup-config

 

... update:

scratch that, even with this (and a reboot) the switch still spams with DNS requests...

This is still a problem. I updated firmware on 1 of my switches and now it is constantly spamming DNS queries for the domain `omada`. 

 

The no controller discover command did not work for me and I do not have cloud controller enabled. 

 

How do I make this stop ?

  @ishanjain28 You don't. TP-Link apparently refuses to fix it.

It's actually implemented for some devices in the next release; if your devices have pre-release firmware available, look for the "Remote Adoption" feature.

 

Unchecking that box will stop the DNS requests. As for when it is slated for official release, unfortunately, I have no news on that.

  @NeilR_M Glad this made it in to some recent firmware release notes, but I am not finding the option in the UI. Do you know if this is command line only on switches? Thanks

 

I figured it out, in case anyone wants to disable the dns spamming if you're running your switches in standalone mode:

 

- SSH into the switch or use the console port.

 

Type these commands:

- enable

- configure

- no controller dns-adoption

- exit

- copy running-config startup-config

- exit

- exit

 

In the GUI, click Save at the top for good measure.

  @smithj33 It should be in the GUI as well, not sure why it wouldn't show up there. What switch specifically are you looking at? And are you certain the firmware update applied properly?

  @NeilR_M I updated 3 switches. SG2210XMP-M2, SG2218P and SG3428X. All updates applied properly and nothing in the GUI. The controller GUI settings didn't change at all. But the command at least works from the CLI, so i'm happy with that.
