    Posted Jul 18, 2014 04:18 PM

    Hi,

    Is there a recomendation for the number of IAPs in the same cluster?

     

    Is there a number of SSIDs or segmentariton issue that can influence in the performance? 

     

    I will use 50 IAPs 115 in the same cluster and I need to give some advice.

     

    Tahnk you.

    You can technically support an unlimited number of Instant APs in a cluster, but the recommendation is 128.

     

    In general (RF best practice, controller and controller-less), for best performance, you should not exceed 4 SSIDs.

    If I need more than 10 SSIDs, can I segment in more than one cluster to

    Tks, mitigate the performance problem?

    You can do 10, it's just not best practice in regards to air time.

    The best practice means in a single area, so you can different SSIDs on different APs in the same cluster.

    Would you need all 10 SSIDs advertised across all IAPs or would you need a few SSIDs on one IAP and a few on another?  If you want different SSIDs on different APs you can use the AP-Zone feature that just came out with v.4.1.

    Actually, I need to propagate 10 SSIDs in the entire cluster or in each cluster.

    You can do that.  IAP supports up to 16 SSIDs with the "Extended SSID" feature enabled.  However, as cappalli mentioned that many SSIDs may hinder performance.

     

    Take a look at the attached doc.   It is a bit dated, however, the concepts are still current.

    Here is another interesting article about SSID overhead

    You will find out a ssid overhead calculator as well

     

    http://www.revolutionwifi.net/p/ssid-overhead-calculator.html

     

    You should have recommended just 2 SSID and MAX 3 SSID

     

    Why do you need 10 SSIDs???

     

    Cheers

    In this case the customer will sell the resources using the each SSID to 3 party providers, like an Airport.
    I think that it is possible to solve this problem using Clearpass.

    You guys have to find a way to not propagate 10 SSIDs... This will make the wifi really slow, and the custumers might start complaining about the wifi service.   And the one that bough it then  will think Dell rebranded wifi is really bad, when its not.

     

    I know its confidential but we would need to understand how does this work so we can find a way to reduce those 10 SSIDS to 3 at least.

     

    Cheers
