During vlan configuration for my new lab (see previous post Home Data Center)
I had to change some vlans, for some reason my  Hybrid Cloud Device Management controller got “lost in translation”

The setup:
1 x Mikrotik CCR1036-12G-4S-EM
1 x UniFi switch 16 150w
1 x UniFI Cloud Key

It all starts with the adoption of devices onto the cloud key – no problems there.
But when your Cloud Key is lost in a vlan with no connectivity or access to other devices, then its back to basics.

My problem was that I deleted the valid networks/vlans added on ports – BIG mistake!
So nothing really works and you can’t change anything, but tuning a bit on the vlans on the router seemed to open up a bit.

I was able to SSH into the switch (It’s running BusyBox)

From there we can SSH to localhost on port 2222
Click anykey to get the Warning!: The changes may break controller settings and only be effective until reboot.

It will not give a response and will be awaiting a key stroke before your ready to go

Keep in mind all configurations will be lost, once connected back and provisioned by the cloud key.

To enter user privilege mode type: Enable
To enter Global Config mode type: Configure

And now we can configure the entire switch (also without the controller and more advanced settings.

In this case,
Selecting an interface (port 2): interface 0/2
adding a vlan to the interface (port 2): interface vlan participation include 22
and your lost Cloud Key should now be back on the correct vlan.
If you just need to bring back to management network on the switch, you can use: network mgmt_vlan 1
Note: 1 being the vlan you want to participate in.

NOTE:
If you need multiple vlan on 1 port – maybe with a UniFi AP AC Pro, you will see that the AP doesn’t have a configuration for management vlan, so we need to configure the native LAN for the device. It only requires 3 steps, it can be a bit confusing configuring and adding a bit more complexity.

– Defined Netowrk/VLANs in Controller Settings
– Manage or Create Network Profiles for the switch in the Switch Configuration
– Assign Networks/VLANS or Profiles to the Port(s)
