Clients not get IP address from DHCP server

[mamadou_oury_di]

Hello

I am on a project in which I have to depoiloyer vSZ 5.1.0.0.496 and AP R510 for one our customers. Diagrams below.
But I have a problem because the clients cannot get an IP address from the DHCP server.

Any suggestion will be welcome.

Thank you in advance

If configured tunnel mode, have change to distribution mode.

Did you checked from wired connection?

It's have to change to tunnel mode because your DHCP server is in DC.

yes it works with wired connection

So that means that I should install the Data plane (vSZ-D)?
