Hi Michel,
I guess you are referring to the ip helper-address command on older ProCurve/Aruba AOS-S devices.
The command is still available in the in the DHCP relay settings.
I'm linking the IP Services guide for 4100i/6000/6100 switch series:
https://www.arubanetworks.com/techdocs/AOS-CX/10.10/PDF/ip_services_4100i-6000-6100.pdfThe explanations from this topic start on page 61, but you can find a configuration example for what you are looking for on page 63:
switch(config)# dhcp-relay
switch(config)# interface 1/1/1
switch(config-if)# vlan access 100
switch(config-if)# exit
switch(config)# interface vlan 100
switch(config-if-vlan)# ip address 198.51.100.1/24
switch(config-if-vlan)# ip helper-address 10.10.20.209
switch(config-if)# exit
switch(config)# dhcp-relay option 82 replace mac
switch# show dhcp-relay

Subject: Aruba cx 6000 dhcp problem
Hi,
I would like your help. I have configure my new 6000 sw but my client doesn't get dhcp .
I did know hoe to configure "ip-helper" in the old SW version but in CX things have changed.
I have vlan 24 for domain pc that need to get dhcp.
i can ping the gw for the sw mgmt but not the gate way for the dhcp.
Thank you,
Michel vaillancourt
