Cisco 3504 WLC - HA options and licensing

[simonvanm]

We are proposing the new Cisco 3504 Wireless LAN Controller for a project but the datasheet is not entirely clear on the HA options.

• Previous models (like 2504 or 5508) had the HA SKU unit, which could be used for N+1 HA (or clustering on the 5508) without additional license fees - the HA unit supported the maximum amount of APs for 90 days. This does not seem to be the case for the 3504. Has Cisco abandoned the concept of the HA unit with this new 3504 WLC?
• The WLC 3504 Release 8.5 Deployment Guide mentions that the 3504 WLC now supports clustering. As there is no HA SKU available, does the secondary controller need the same level of AP licenses as the primary controller? Or can a standard unit without licenses be converted to a HA model?

Thank you...
Simon

Hi everyone, I just have a question, Once we break the HA, the configuration remain the same in Both controllers? I think the only thing that I have to do is configure a new management ip for standby controller and the configuration will remain the same? of course I also have to update configuration for some interfaces but I gonna be able to have 2 controllers working on stand alone mode right?
