Customer is looking for two numbers WLAN Controller (AIR-AP1242AG-E-K9). And they want to configure as ACTIVE-ACTIVE. I would like to know whether it can be configuring as ACTIVE-ACTIVE.
And Is really require WLAN Controller for AIR-AP1242AG-E-K9 access point ? or it can be configure without WLAN controller ?
Please revert me ASAP
In the WLC world this is how an AP is covered in case one WLC fails. It is not without some "downtime" in case of failure but both Controllers are active. You have to keep in mind that an AP can only be registered to one WLC at a time so this is the best that you can do :) When one WLC fails the AP then has to re-register with the backup, this is not a completly seemless process.
Hope this helps!
