Please see this page, for example. Perhaps it is the same software version
as your switch?


ip dhcp relay address

The ip dhcp relay address global configuration command defines the DHCP
servers available for the DHCP relay. To remove a server from the
available DHCP servers list, use the no form of this command.


ip dhcp relay address ip-address

no dhcp relay address ip-address

        ip-address—DHCP server IP address. Up to 8 servers can be defined.
