WLC 5508 Licensing Question

Unanswered Question

User Badges:

I have 2 5508's in an Active/Active configuration.  They each have a 12 AP Permanent License.  The each also have 10 AP's that are assocated.  Each AP is configured with the Primary and Secondary controller.  If my primary dies, will the secondary allow the AP's that were on the Primary to associate even if it is over the 12 AP license?  I ask because I know with the new SSO model it will allow them to associate for 90 days before barking at you if you are over the limit.

With your setup, no. The most will be 10 and the other 2 will not join. With AP SSO or N+1, you have the second WLC that is an HA Sku or the second would need to have 50 ap license minimum.

Licensing for HA Pair



A HA Pair can be established between two WLCs running in these combinations:


     One WLC has a valid AP Count license and the other WLC has a HA SKU UDI


     Both the WLCs have a valid AP Count license


     One WLC has an Evaluation license and the other WLC has a HA SKU UDI or Permanent license



One WLC has a valid AP Count license and the other WLC has a HA SKU UDI



     HA SKU is a new SKU with a Zero AP Count License.


     The device with HA SKU becomes Standby the first time it pairs up.


     AP-count license info will be pushed from Active to Standby.


     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.


         In order to lower AP count after switchover, the WLC offset  timer will continue and nagging messages will be displayed after time  expiry.


     Elapsed time and AP-count will be remembered on reboot.


     The factory default HA-SKU controller should not allow any APs to join.


Both the WLCs have a valid AP Count license


     The CLI should be used to configure one WLC as the Standby WLC (as  mentioned in the configuration section) provided it satisfies the  requirement of minimum permanent license count. This condition is only  valid for the 5500 WLC, where a minimum of 50 AP Permanent licenses are  needed to be converted to Standby. There is no restriction for other  WLCs such as the WiSM2, 7500, and 8500.


     AP-count license information will be pushed from Active to Standby.


     In the event of a switchover, the new Active WLC will operate with  the license count of the previous Active WLC and will start the 90-day  countdown.


     The WLC configured as Secondary will not use its own installed  license, and only the inherited license from the active will be  utilized.


     After 90-days, it starts nagging messages. It will not disconnect connected APs.


     With the 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.


         After switchover to a lower AP count, the WLC offset timer will  continue and nagging messages will be displayed after time expiry.



One WLC has an Evaluation license and the other WLC has a HA SKU UDI or Permanent license



     The device with HA SKU becomes the Standby WLC the first time it  pairs up with an existing Active WLC running Evaluation License. Or, any  WLC running a permanent license count can be configured as the  Secondary unit using the CLI configuration provided if it satisfies the  requirement of minimum permanent license count. This condition is only  valid for the 5500 WLC, where a minimum of 50 AP Permanent licenses are  needed to be converted to Standby. There is no restriction for other  WLCs such as the WiSM2, 7500, and 8500.


     AP-count license information will be pushed from Active to Standby.


     In the event of a switchover, the new Active WLC will operate with  the license count of the previous Active WLC and start the 90-day  countdown.


     After 90-days, it starts nagging messages. It will not disconnect connected APs.


     With new the 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.


         After switchover to a lower AP count, the WLC offset timer will  continue and nagging messages will be displayed after time expiry.
