Hi,
1. Do I need to configure both AP with diff IP or One AP will join to another (working as master wlc)automatically ?
You need to setup APs independently first.
2. Both AP is capable of become a ME Controller so How can i stop to one controller to not take part in that process ?
Yes, you can define which one will be the master by running the command "config ap next-preferred-master <Cisco AP>".
Otherwise, they will start a process to device which one will be the master.
