I have a handful of 3800 series aironets. I have switched them to ME mode and all works as expected other than failover. The docs state that when an AP running the controller goes down another ME enabled AP should pick up the controller role and the management ip, config, etc should be passed along with it. This does not appear to be the case for me. One of the APs will end up launching the controller role but it will start in provisioning mode rather than with the previous config. I've read through all the docs and can't find any additional info as to why this may occur. Thanks in advanced
Solved! Go to Solution.
If you are referring to the next preferred master setting I have tried that as well. The doc states that this should not be required and that it is not recommended but regardless this did not help. The issue appears to be due to the actual configuration not syncing between devices. The other APs will pick up the controller role but it initializes as if it is a fresh controller without a config (provisioning mode)

Are the other APs on the same Vlan than your current Master AP ?
You can check if your Surbordinate APs are ME capable AND synced :
- Show version (Your AP should have a ME image and be ME capable)
- sh flash config-sync (make a change on the Master AP and you should see on the surbordinate APs their config synced with the master with a timestamp in the flash)
