Cisco WLC3504 as "HA-SKU Secondary Unit" for vWLC

Hello Folks,

Is it possible to use Cisco WLC3504 as "HA-SKU Secondary Unit" (zero license, fallback for APs, non-SSO) for Cisco Virtual Wireless Controller (vWLC) ?

Re: Cisco WLC3504 as "HA-SKU Secondary Unit" for vWLC

As your meaning, you want to make WLC3504 as a "N+1" mode secondary WLC.

First, WLC3504 support RTU license:

RTU licensing is supported only on the following Cisco Wireless Controller platforms:
-Cisco 3504 WLC
-Cisco 5520 WLC
-Cisco Flex 7510 WLC
-Cisco 8510 WLC
-Cisco 8540 WLC
-Cisco vWLC

So you can config the licenses by this commands:
Procedure
Add or delete the number of APs that an AP license can support by entering this command:
-license {add | delete} ap-count count
Add or delete a license for a feature by entering this command:
-license {add | delete} feature license_name
Activate or deactivate an evaluation AP count license by entering this command:
-license {activate | deactivate} ap-count eval

Or you can config license by GUI:
Procedure
Step 1
Choose Management > Software Activation > Licenses to open the Licenses page.

Step 2
In the Adder License area, choose to add or delete the number of APs that an AP license can support, enter a value, and click Set Count.

Step 3
Save the configuration.

Note:
After you add or delete the license, WLC must use the save config command to save the license.

You can use the WLC3504 as a secondary unit after that. it can be supported 150 aps and 3000 clients in centralized mode.

Thanks for the hint. 

Q. How does licensing work in N+1 High Availability mode?
A. Simply add the amount of licenses that you have purchased to all controllers. There will be no license violation as long as the number bought licenses is higher or equal to the total number of joined APs on all controllers in N+1 High Availability.
