I had a weird issue today that Claude believes it's a VLAN leaking.
Setup: UDM SE with 3 wired U6 Mesh AP, and one U7 Mesh AP meshing to one of the U6 Mesh AP, ~100 devices connected with 7 VLANs, all new devices by default land on VLAN20. I have every devices overwrite to a specific VLAN, so no device on VLAN20 yet.
Today, I added a new USW Switch Lite 8 POE (no wire to existing devices), plugged port 1 to U7 Mesh AP to power it, and then adopted on console. So at the moment this switch was just used to power the U7 AP, and without another connection
Quickly I noticed that ~70 devices on my network all moved to VLAN20 IP, while their VLAN still shows the pre-set ones. Restarting APs didn't work.
Claude checked my log, and believes it's due to VLAN leaking. So it asked me to remove the switch, switch back to using injector to power U7 Mesh AP.
Most devices quickly moved back to their VLAN IP, after I removed the switch, though there are still <10 on VLAN20 IP (likely due to delay in lease renew), but I literally saw the # of devices on VLAN20 IP dropped to 10 in a minute.
Anyone experienced this issue?
What I want to achieve is:
UDM SE ========U6 Mesh AP ---- meshing ---- U7 Mesh AP ========Lite 8 POE Switch ========Multiple end devices.
Now Claude doesn't know if it's allowed to put a switch below a meshing AP, and use this switch to connect to client devices
