Hi Juilan,
Please check the output for "show datapath session table <ipaddress of client>
The above command will only show the traffic which is sent to the controller (Tunnel mode).
The traffic for bridge mode SSID will not show up in the above output. You can check it with the command:
show datapath session ap-name <name of the AP>
The above command will show the bridge mode traffic as client traffic is bridged by the AP.
