Hi  @A_Mansoor 

It seems like it's a display issue?

From the screenshot, the clients have obtained the correct IP addresses from the correct VLAN.

Did you try to refresh the pages? what are the SDN devices you are using?

  @A_Mansoor

What kind of portal did you configure?

Please also let us know the firmware versions of the devices.

If disconnect one client and reconnect, will it display the VLAN ID?

Hi  @A_Mansoor 

Did you configure portal authentication? 

What kind of SDN devices are you using? Please kindly send a screenshot of the Device page.
