Can I set Catalyst C9124AX as a Client

if i understand your requirement, you want to use AP to connect to other AP use as client ? what is the use case here ?

[wlkang]

Right, I have to Catalyst C9124AX.

I want to use 1 C9124AX as AP, 1 as Client of that AP.

Is it possible? If possible, any procedure to set available?
