Well I have an HA unit racked

Well I have an HA unit racked, powered and still waiting to be married to its primary.

So I took a look and the only thing I can see is that the HA unit has NO licenses attached.

That being said, the only difference between an HA and a non-HA is a license count.  A base 5508 has 12..  which yours seems to have.  So while it can be used stand-alone (it has 12 seats) you can still use it in an HA role.

Hi David,

Hi David,

I think that your problem is different from my question.

I suggest to you to read this post:

Best regards

i have already found this

i have already found this post before but it doesn´t help me because the main question how i encounter that i have the correct SKU at the moment is not clarified with that. at least i can not encounter it

Hello Heinz,

Hello Heinz,

Standby WLC
This is the WLC that is monitoring active controller in HA pair and ready to take over the wireless network in event of Active WLC failure.
Secondary Unit
In AP SSO deployment controller running lower or equal permanent count lic should be configured as secondary unit OR controller with HA SKU UDI (zero AP count lic) is shipped default as secondary unit. Secondary Unit is the WLC, which will take the role of Standby WLC first time it forms HA pair. Secondary unit inherit the lic count information from its peer i.e. Active WLC via redundant port.


as your controller has a 12 AP license it would suggest it is not really a HA SKU.

It can be used a a stan-alone controller for max 12 AP's.

But it can be used as a secondary unit in a HA pair (lower or equal AP count license)

HA is a development that was introduced when only standaard controllers (with AP license) were available.

But because customers complained about the unused AP licenses in a HA environment, Cisco later introduced a controller with zero AP license.

But more important is if your active controller has an HA license to make HA work!

fortunately you were not

fortunately you were not right. after pairing the information gets much clearer

(Cisco Controller) show>license capacity


Licensed Feature    Max Count         Current Count     Remaining Count
-----------------------------------------------------------------------
AP Count            500               1                 499

(Cisco Controller) show>license feature


This command is Not allowed on a HA-SKU Controller

(Cisco Controller) show>license summary

This is a Controller with HA-SKU license.

so in the end i have a HA-SKU controller. but it´s confusing when it is not paired to understand whether you really have one.

your last post is confusing?

your last post is confusing?

where come these 500 licensed AP from?

do you have it paired now? then the licenced count comes from the primary!

if it is stand-alone, then it's from a different controller than in your original post:

NAME: "Chassis"    , DESCR: "Cisco 5500 Series Wireless LAN Controller"
PID: AIR-CT5508-K9,  VID: V04,  SN: xxxxxx

(Cisco Controller) >show license capacity
Licensed Feature    Max Count         Current Count     Remaining Count
-----------------------------------------------------------------------
AP Count            12                0                 12

yes, i also mentioned it

yes, i also mentioned it above: i have paired the devices now. since then the controller took over the 500 licenses from primary controller

Bronze

Sorry missed the "after

Sorry missed the "after pairing " in your post, but it's there.... :-)

Cisco's info is my previous post says

HA-SKU is shipped as secondary unit.

"normal" controller with AP count must be configured as secondary unit.

Not sure if i understand this

Not sure if i understand this correct. the documentation says:

  • With Release 7.4, an HA-SKU secondary controller can be configured as a backup controller for N+1 HA. For example, the following can be used as an HA-SKU controller:

5508 Series Standalone controller with 50 AP license

so 12 seems to be not OK...???

This is how I verify it:

This is how I verify it:

VIA CLI:
1. Access the target device via its Serial Console
    -Another option is to make it Primary to access it via remote(SSH)

2. Invoke the ff. commands

#show license summary

       -MESSAGE:
      This is a Controller with HA-SKU license.
      The AP base count license was inherited from the Primary Controller.

#show license status            -This command is rejected in HA-SKU device

       -MESSAGE:
       This command is Not allowed on HA-SKU controller


VIA GUI:
1. Make the target device become the Primary
-Upon logging-in to GUI, a countdown timer appears that starts at 90 Days


TIP: I'd advise using the CLI to avoid failover process :)


My two cents: Considering your WLC has an AP count, im pretty sure it doesn't have a HA-SKU license
As far as I know, you get a WLC with HA-SKU license upon order

Note that HA-SKU is just a licensing scheme w/c allows consumers to not buy anymore AP licensing for the secondary in HA setups(using SSO)
