Alcatel Unleashed

Good day can anyone maybe help or advise

I have a customer running on OS6360, OS2360 and OS2260 switches, the OS6360 switches are running on version 8.10.105.R02 and its only the OS6360 switches seeming to be an issue. All switches Spanning Tree are set to Per VLAN but it seems the OS6360 after a few days keep on setting the Spanning Tree mode to RSTP automatically causing the ports the Wi-Fi AP's are connected too, to go into blocking mode and the Wi-Fi stops working. When I change it back to Per VLAN all starts working again. Why will this happen on the OS6360 switches?

Please see screenshot attached and config below

I'd start with disabling auto-fabric. I've seen it cause strange things.
Anyhow, what's connected to 1/1/4? That port is not under your UNP rules and that's the port you are experiencing the issue on according to your screenshot.
Is this happening only for vlan 100?

on port 1/1/4 is a Unify AP and VLAN 100 is the WLAN VLAN, I removed UNP for the Wi-Fi as it seems it causes issues on the Unify AP's. It seems like the Unify AP's dont like UNP, yes and it happens only for VLAN 100. I did notice on Omnivista Cirrus that it states the firmware the 6360 is running on is a problematic version. I have never seen this issue before so I am lost. So you think I should disable Auto-fabric?

Upgrading to the latest version is always a good idea obviously
And assuming you posted all the config, you don't have a classification rule for that Unifi AP so the AP would go into vlan 10 and not 100.
Also the defaultWLANProfile profile is only designed to work with ALE APs (at least that's how I understand it). I believe you'd have to classify the AP's mac into vlan 100 and then classify ingress vlan tags into their respective profiles.
Do you perhaps have wireless phone on the wifi?
Does the issue still happens when you are not using UNP on 1/1/4?

The ports the AP's are connected too are manually configured so the default VLAN for the AP's are VLAN 100 and then VLAN 10, 50, 60, 70, 80 and 81 is tagged over the same port. And yes even with the manual config the port goes into Blocking mode. What I want to know is why will the switch change the Spanning Tree mode from Per VLAN to RSTP by itself and then block the AP ports?
