The other day we ran into an issue where we lost access to our entire unifi stack.
And can no longer access our unifi controller to make any configuration changes. Do know that this network had been working for well over a year and then suddenly stopped working. The switches no longer have ip address and their are multiple of them. I have a concole cable but am trying to find a few things.
1.) How from the command line can we add a vlan to a port?
2.) How can we find out who changed the config on the unifi system controller, assuming this is not a bug and someone isn't confessing to doing it.
3.) How to set a static IP on the switch directly via the cli?
