controller load

Hi,

 

We have a  sudden increase in the number WLAN users after we embrace BYOD, now WLAn is slow, how would I measure the controller load and traffic to make sure that our controller is resource capable of handling the current traffic/no bottleneck in terms of controller hardware.

 

Thank you

Re: controller load

Take a look at:

 

show datapath utilization

show cpuload

 

Also, it also wouldn't hurt to make sure that you are saturating your uplinks into the controllers.

noninterference,

 

Wifi contention is typically the problem before controller network utlization/resources.   A good rule of thumb is to have a gigabit port for  each 100 access points you have connected to the controller.  Check to see what else could be your bottleneck here:  http://community.arubanetworks.com/t5/Technology-Blog/Removing-the-Bottleneck-in-Wireless/ba-p/77978

Re: controller load

More data is needed here, what controller, how many ap's, how many users.  How is your network designed, could this be a broadcast issue, possibly turning on the  BCMC (Broadcast-Multicast) Optimization feature may take care of it?

Re: controller load

A 5 minute wireshark while 'parked' on an SSID would be a good idea.  Then evaluate the 'pie chart' for proportions of BC, MC, Protocol A, B, C.      "Before" info is valuable to have as we manipulate the Nerd-Knobs to tweak performance and gain "After" performance data.
