Cisco 3850 Wireless Controller "debug client"

[5bswan]

This is probably a dumb question, but I can't seem to find an answer anywhere.  We've got a 3850 wireless controller in a lab running 16.2.1 with a couple access points.  We're having a problem where clients seem to disconnect "for no reason" about every 15 minutes or so.  If this were a "standard" WLC the first thing I would do is a "debug client <mac>" and see what's going on.  However, I don't see that command anywhere.  I looked through the debug commands and nothing is jumping out at me as being an equivalent of a "debug client" on a 3850.  What's the right way to see all the low-level troubleshooting info for a wireless client on this platform?

Thanks!

Hi Brian,

This is actually a very good question :). There does not seem to be a debug command for this. You will need to use traces. To be specific 'set platform software trace' to set traces for the required modules and 'show platform software trace' to show the trace output.

I will need to get my 3850 switch free before I can fire it up with this code to get you the exact commands.

You can also use the following commands to check client details:

show platform software fed switch 1 wireless client summary

show platform software fed switch 1 wireless client client-index <index> summary

... ahh, I didn't even think of all the "platform" commands.  I'll take a look at these.  Thank you very much for your help!

Hello,

These commands will not work on the 16.x release anymore. Traces need to be enabled with: 'set platform software trace'.
