We are started seeing the issue where some of the RAPs are losing its configuration like ipsec parameters, master ip automatically.
This happens only for random APs.
Found that these were the APs which were showing mismatch status on the Airwave.
Also Airwave was changed to manage mode for sometime to collect some information.
Once the Airwave was changed to monitor mode this occurrence has stopped.
If the Aps are in managed mode and if the Airwave sees a mismatch status/configuration it may try to match the configuration it actually holds.
If the reference configuration doesn’t have master ip, rap configuration or the values are empty, this situation may happen.
So kindly be careful in changing the mode to manage mode.
