How does licensing works for two local controller

Hi all,

 

My current environment have two local controllers which runs on LMS and backup LMS.

 

Controller A

512 AP license

229 AP active

 

Controller B

512 AP license

280 AP active

 

Our current concern is that when controller A goes down, the APs will be failed over to the backup LMS which is controller B. Does the AP from controller A consume the license of controller B when it fails over?

RE: How does licensing works for two local controller

If centralized license is not enabled in the controller redundancy configuration, You will use the licenses of each controller. If you have centralized license enabled, you will be sharing the entire license. If one controller fails, the active license to the controller is retained for one month and then reclaimed.

Re: How does licensing works for two local controller

Central license server runs on a master controller and can be redundant by use aan master standby controller (6.x).

In 8.x central license server is a function of the mobility master and can be redundant with a second mobility master at no extra cost.

When you dont have a central license server and want some, you have to migrate your licenses on the hpe licensing portal.

Re: How does licensing works for two local controller

We do not have a master controller in our environment, so each controller have their own 512 AP license. 

 

We're planning for future expansion so my concern is if we add more APs to either controller, will it consume the license of the secondary if either one of the controller were to breakdown?

Re: How does licensing works for two local controller

Without the master controller, you can not make all the settings.

The Aruba WLAN solution consists of a master first and an additional controller locally.

One of the two controllers will act as the master controller.

If cli config is done as below, it can be confirmed by the result value.

(Aruba3200) #show switches

Re: How does licensing works for two local controller

Both my controllers are indicated as master. 

 

Our environment is not a master/local environment, it is on a local/local environment, hence centralizing the licenses is never an option. 

 

As stated both our controllers have 512 licenses each and are utilitzing 229 and 280 AP individually.

 

Our LMS is set as such and vice versa.

LMS IP 10.167.30.17 (controller A)
Backup LMS IP 10.167.30.27 (controller B)

 

If 10.167.30.17 goes down, 229 AP will be failed over to controller B and the total number of AP will be at 509, which is close to the license amount of 512.

 

If we were to expand our network to additional 20 APs, it'll exceed the license count of 512. Will the fail over AP consume license of either of the controller?

Re: How does licensing works for two local controller

If the rules for the current controller are defined, it is the master master configuration. In each, you can set up a centralized license setting as a peer server. You can share the license as you explained it first. What is the capacity of the controller? Is it a model that can accommodate up to 512 aps? First, you'll need to be able to accommodate more than 512 controllers.

We do not need to centralised license, both controllers have 512 AP license each which is the maximum for Aruba6000 controller.

Woow, confusing topic.

 

First, local-local does not exist. 

With 2 Aruba6000 controllers you are either running them in:

a) master-master

b) master-local

c) 2x standalone 

 

Regardless of all that, you can never load more than 512APs on a single Aruba6000/M3. This is a built in limit regardless of licensing.

 

For us to figure out what setup you have, please provide the out put of "shows switches" and "show master-redundancy" for both controllers.
