Cisco 9800-L-C Trace-on-Failure Command

[Gehrig_W]

Hello Cisco 9800-WLC-expert,

we are troubleshooting a 9800-L-C performance problem.

The box is collapsing when many users are conected and showing no traffic nor correct DHCP-handling.

I would like to use the follwing command  according to a Troubleshooting Playbook shown in Cisco Live BRKEWN-3081 page 27

WLC-9800-Guest#show logging trace-on-failure summary
This command has been deprecated and is no longer supported. Please use "show logging ... trace-on-failure ..."

Ok, let's use this one:

WLC-9800-Guest#show logging ... trace-on-failure ...
^
% Invalid input detected at '^' marker.

Can someone please put some light on the correct usage of this command ?

Thank You in advance

Greetings

Win

Does anyone know the correct syntax ?

Try this command:

show logging profile wireless trace-on-failure ?
