Did you put a helper address on the L3 SVI interfaces on the L3 switch?

!
interface vlan 2
ip helper-address 10.0.0.3
!
interface vlan 3
ip helper-address 10.0.0.3
!

As the DHCP server has an address in Vlan 1 (10.0.0.3), the VLAN1 SVI doesn't need a helper address. All other VLANs/Subnets which need a DHCP address will need a helper address on their SVI.

 

if i changed the native vlan to vlan 10?what would happen?

that time too not needt to mention ip helper address for vlan 1 or vlan 10?
