@MandarKulkarni,

What device do you want to actually hand out the addresses? In most situations like what you appear to be describing, the ip helper address configuration will point towards a DHCP server so that it will distribute addresses instead of the switch. In that case, there is no need to configure DHCP Relay on the firewall itself as it's already being handled by your switch and your DHCP server.

this depends if you want the firewall to also relay the dhcp, or not
