At the moment I have three ubiquity unifi setups running. One offline (config & forget), one onside & one webbased.
The Webbased solution works ok, but it sometimes fucked me up. But it wasn’t possible to put both on the same network, because the controller were still running on a legacy hp switch setup and I woun’t change / migrade the vlan’s.
This couses some problems with the firewall and after a uplink firmware outage reconfig of some ports were not possible.
The webinterface say that the ports have been provisiont, but when I connect myself to the port, there were no or still the old network…
So I try to reprovision the switches, but even after giving the controler a second nic inside the controll network, the fucked up ports were not working well, even after forced reprovisioning.

That sucks hard.
I’ve done some resurche and find a blogpost from Dan Langille: https://dan.langille.org/2018/01/12/getting-into-the-cli-for-a-unifi-switch/
Ok, remembering the ssh PW for the network devices, ssh into, do „telnet 127.0.0.1 2222“ / enter / „enable“ / command (Strg) + c / press c and now I’ve a switch config terminal that warnes me that config will reset to the past saved config after reboot.
That’s fine, I only want to check the port config.
„show vlan port 0/3“ -> the VLAN list were empty, but there should be 15 in the list -> back to the now „locally connected“ and dns faked controller -> set the port to a bulshit VLAN & back to all.
And now – Port is working fine and the 4 switches behind it get connected again.
