WLC HA SKU Licensing Issue!!!!

[yogesh rajguru]

Hi Team,

We have received HA SKU WLC 5508 with no License. As per Cisco Documentation, by default HA SKU Standby WLC will be working as an Redundant WLC instead of Load-Balancing + Redundant WLC.

During the Primary WLC failure, the Standby WLC will retain its Role and here, the 90 Days timer will start.

Now, our doubt is, once the Primary WLC is up, what will happen to 90 Days Timer, will it reset?

• On event of Active failure, HA SKU will let APs join with AP-count obtained and will start 90-day countdown. The granularity of this is in days.
• After 90-days, it starts nagging messages. It will not disconnect connected APs.
• With new WLC coming up, HA SKU at the time of paring will get the AP Count:

– If the new WLC has a higher AP count than the previous, the 90-day counter is reset.

– If the new WLC has a lower AP count than the previous, the 90-day counter is not reset.

Hi,

Thanks for the Information but still we have couple of doubts: 

What do you mean by New WLC, is it Primary WLC?

What does AP Count mean here?

Are you considering "Fail-over scenario where WLC restarts" or considering the "Fail-over scenario where WLC is having Hardware Problem and need to be replaced".

We have gone through the Cisco Document and because of these doubts, our implementation has been stuck.
