The correct command set for configuring a Cisco Catalyst 9800 Series Wireless Controller so that the client traffic enters the network at the AP switch port is Option C:

config terminal

wireless profile policy [policy name]

no central switching

end

This configuration disables central switching, which means that client traffic will be locally switched at the access point level rather than being sent through the controller. This is useful in scenarios where local switching is preferred due to reasons such as reducing latency or conserving bandwidth on WAN links. References := ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )
