Wireless Access

Is there a way to check this out?

I would like to know this becasue for example, a AP 135 got better cpu and memory, which will handle more clients than for example an AP 93 which got less cpu and memory.

I can check the porcentage of the channel utilization, to see if something is going wrong in there but what about the ap capacity? the hardware? is there is any way to see this?

On the controller or Airwave

Cheers

 This is 6.3.

 Typically the medium, as in the RF is the bottleneck much sooner than the CPU would be.  The AP93 does not provide 3 streams or dual simultaneous radio capability in the first place, so it is limited by it's RF capability in the first place.  The AP135 does provide 3 stream capability with dual simultaneous radios, but it cannot provide access to 80 mhz channels like the AP225.  The circumstances would have to include many, many clients to tax the CPU.

Thanks Collin!

May i know the threhold? for the CPU and memory?

When i need to pay it attention??

A custumer is asking me this, ill do explain them what you just did but i would like to give them the answer to what they asked in first place anyways.

It is very far down on the list of things that we would even look at.  It is not something a customer should be concerned with because unless it is a bug, the RF is an issue much, much sooner.  CPUs go up and down and sometimes they are temporarily high; in those circumstances, TAC is trained to collect that data and determine if that is the issue.  I typically would not tell customers to monitor something when other things are the problem much sooner that they should focus on.  I do not know what the threshold is and we rely on engineering through TAC to tell us what is high or not.

So you think they should put just attention the Channel utilization?

Absolutely.  Whatever is on the Dashboard page is what is important.

Thank you very much for your wise advice :)

Nightshade1,

That is the ONLY advice.
