IAP Cluster Limit

Currently I have 52 IAP 104's and 5 IAP 135's in a single cluster running 6.3.1.2-4.0.0.3  and tried adding 9 more to it today.  Unfortunately this did not work around  and my cluster died, lost its VC or crashed, still trying to figure out what happened exactly. I lost connectivity around 59 AP's.  

 

My question is what is the limit of AP's I can put in a single cluster?  Also I have read that if I were to make one of the 135's the master it may handle this a little better?  Can you assign a 135 to be a preferred master?

Re: IAP Cluster Limit

There is something wrong... you should open a support ticket

There is no limit on the cluster size...

And yes its recommended that you put a AP 135 as Master of the cluster...

Re: IAP Cluster Limit

Really Clembo?

Marcus told me that there was no limit... or at least thats what i understood... the only AP that got a hard liimit is the AP93

 

You can elect the master or have preference with the preference enable here:

Re: IAP Cluster Limit

Not sure if work load takes into account but the cluster averages 400-600 users a day.  When I added the additional AP's the user count was around 510.

Re: IAP Cluster Limit

Well as far i know the suggested limit is up to 2000, the thing is that is not a hard limit... but is recommeded not going beyond that...

I remenber i also read a post of marcus which said it was unlimited, im searching for it.

Re: IAP Cluster Limit

I am verifying this Carlos.   I always thought the same, but came across a doc that says otherwise.  I am confirming.   The article I am referring to can be seen on AFP:  https://afp.arubanetworks.com/afp/index.php/IAP-105#Limited_Scale.2C_Single-site_WLAN

Re: IAP Cluster Limit

Hello Chris!

As far i remenber before he would tell me that the suggested limit was 64.  But then with the new firwmares the suggested limit was a bigger than that...

Thanks for the document!

Re: IAP Cluster Limit

Yes, seems the information in that linked document is outdated/incorrect.    In fact, a fellow SE shared info on their 180 IAP-105 cluster at a hotel in Turkey.

Re: IAP Cluster Limit

180!

thats a lot :)

 

I guess then there must be something wrong and he should open a support case with the TAC....

The cluster should have never crashed... unless its a bug or something?

 

 

Cheeers
