Thank you for providing me the KB links. I already configured both the controllers for HA. My concern are: - How could i integrate the two controllers in one network? - Do i need to put them together in one switch via a tagged or untagged VLAN? - What port of the EWC to be integrated in the network? - Is it the management or L2 ports? - Will there be a down time in the EWLAN due to the restarting of controllers? If there is any how long will it take?
