How to check for heavy wireless users in WLC?

[Marc Abaya]

Is there a way to see who is consuming the bandwidth most using the GUI or CLI in Wireless Controller, without enabling Netflow? Either finding the IP add or MAC add will work.

On a switch, I can easily do this by using "show interface summary" and it can tell which port is the busiest and then get the MAC add associated for that port. Is there a similar command for WLC?

What model of WLC and what software version you run ?

In 8.1.x onward I think you have nice dashboard, so you can see top users in a dashlet, but I do not think you can filter it by time base and identify a top user in particular time period though. Here is an example of my WLC running on 8.1.x code.

Netflow is the best for those sort of use.

Thanks for the reply. Ours is a 2504 WLC  and older FW 7.6. It doesn't have that feature yet.

Any CLI commands that I can use as a work-around?

In our version, I can open all the connected clients but it doesn't say the usage on the columns. Although I'm curious on how they sort the users on this? Is it by volume?

No.  Upgrade to the latest 8.1.X and this feature is available.

Hi Robert,

you can configure AVC (Application visibility) in WLC, follow this link:

http://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/115756-avc-guide-00.html

After configured you can see by WLAN, application or client the consuming bandwith. Also if you prefer you can check by CLI:

For example:

(Cisco Controller) > show avc statistics client 00:0a:ab:15:00:01 application http
