Dear Expert,
I have a question.
I'm building Wireless LAN Network Systems.
Then I'm configuring at WLC for N+1 structure.
One has base-ap-license, another has evaluation license only (for HA).
According to the Cisco Documents,
The WLC#1 is primary unit and WLC#2 is redundancy unit.
If WLC#1 goes down then All Access Points rejoin to the WLC#2.
Within 90 days, WLC#1 must recover and All Access Points must rejoin to the WLC#1.
How does the WLC#2 recognize own license state ?
Do you know how to confirm the WLC#2's license state ?
I'd like to confirm the remaining time for evaluation license, though.
If you know, Could you please tell me it.
Best regards,
takuro

Hi Takuro,
WLC2(with HA License) comes with a max 75 AP license, this you can see under Management > Software Activation > License. It will be under Evaluation type lic.
To activate it you need to run this command:
(WLC2) >config redundancy unit secondary

Every 100 ms, a keep-alive is sent by the standby to the active controller to check the status. In case of the Cisco 5508 Wireless Controller, Cisco Flex 7500 Series Wireless Controllers, and Cisco 8500 Series Wireless Controllers.
On the HA-SKU UDI controller, execute the config redundancy unit secondary
command to obtain support for Max AP count licenses on a given hardware. Evaluation license does not need to be enabled for this purpose.
When the active controller is unavailable, the standby controller will adopt the licenses from the primary controller. It is expected that the customer will be able to get the primary controller back online within 90 days. After 90 days, the customer will get a daily reminder to switch back to the primary controller.

Dear mohanak,
Thank you for your explanation.
I understood very well.
I guess that the WLC#2 become active, It evaluation license timer count down.
Is this correct ?
If yes, then Could you tell me to confirm remaining day for evaluation licese ?
I guess that it can be the CLI command.
Because, I couldn't find it on the GUI.
Best regards,
takuro.

Hi Takuro,
In my test lab, WLC2 is active from last 4 months and one AP is connected all time still my License state showing (12 week, 6 days).
If primary WLC is down then you can secondary WLC for 90 days or more but best would to make primary WLC functional whiten 90 days.
As per my knowledge ....this is the only command:
(WLC2) >show license summary
License Store: Primary License Storage
StoreIndex: 0 Feature: base Version: 1.0
License Type: Permanent
License State: Active, Not in Use
License Count: Non-Counted
License Priority: Medium
License Store: Evaluation License Storage
StoreIndex: 0 Feature: base-ap-count Version: 1.0
License Type: Evaluation
License State: Active, Not in Use, EULA not accepted
Evaluation total period: 12 weeks 6 days
Evaluation period left: 12 weeks 6 days
License Count: 75 / 0 (Active/In-use)
License Priority: None

Dear Sandeep Choudhary,
Thank you for your reply.
That has become a great help.
I confirmed HA License status by CLI too.
It wasn't change the license period in spite of the WLC#2 is primary.
I don't know that why it period did not change.

takuro.
