Explanation
https://techhub.hpe.com/eginfolib/networking/docs/switches/K-KA-KB/15-18/5998- 8164_mrg/content/ch12s04.html https://community.cisco.com/t5/routing/configure-dhcp-relay-ip-helper-address-need-help/td- the IP helper goes on the first layer 3 device in the path towards the DHCP server. In your case, that appears to be the 3850. Put the helper address on the Vlan interfaces, e.g.: interface Vlan60 ip address 10.233.190.254 255.255.255.0 --> ip helper-address x.x.x.x no ip unreachables
