Throughput problem with Aruba 7220

Hi all,

 

I need some help with Aruba 7220 controller and APs which connected to this controller. We have got an Aruba 7220 controller. We are using AP-105, AP-93 and IAP-225(With controller mode) in production environment. The majority of Access Points are AP-105. As you can see below screenshots we have a throughput problem. The throughput cuts out occasionally.  When the throughput dropped suddenly, the clients continue to the controller but the clients can't access to internet. 

 

Any help or guidance would be greatly appreciated.

 

 

Here are some relevant details for your info:

I would type "Show log system all" to see if anything is happening on the system side.

Thank you for the reply.

I uploaded a piece of system log file. Could you tell me if there is something wrong in log file.

On second thought, do you have a screenshot from the "Performance" Tab?

We probably needed that performance creenshot when you had issues.  The system log does not look like anything bad is going on from a system perspective.  I did see that you have access points that have over 40 users on them at a time.  Please PM me your email address and I will send you a link to send me your logs.tar with tech support so I can take a look.

Hi

 

What about spanning-tree on the upstream switches?

Looks like the system stops transferring data, might look like this if there is something wrong with the topology and spanning-tree re-calculates for whatever reason.

During the recalculation and learning, the upstream device will stop switching.
