set IP on ONU from the OLT

I am working with a ZTE C320 OLT and a FD512XWX ONU brand (CDATA), and a V2802DAC ONU brand (VSOL). When configuring them, none of the ONUs obtain the IP that the OLT should assign them. I am using these configurations:

interface gpon-onu_1/2/8:24 name test description test tcont 1 profile 525MB-U gemport 1 tcont 1 gemport 1 traffic-limit downstream 520MB-D service-port 1 vport 1 user-vlan 3000 vlan 3000

pon-onu-mng gpon-onu_1/2/8:24 flow mode 1 tag-filter vlan-filter untag-filter discard flow 1 pri 0 vlan 3000 gemport 1 flow 1 switchport-bind switch_0/1 iphost 1 switchport-bind switch_0/1 veip 1 ip-host 1 ip 00.00.00.00 mask 255.255.255.0 gateway 00.00.00.00 ip-host 1 primary-dns 8.8.8.8 second-dns 8.8.4.4 vlan-filter-mode iphost 1 tag-filter vlan-filter untag-filter discard vlan-filter iphost 1 pri 0 vlan 3000 dhcp-ip ethuni eth_0/1 from-onu security-mgmt 998 state enable mode forward ingress-type lan protocol web https security-mgmt 999 state enable ingress-type lan protocol ftp telnet ssh snmp tr069

and this configuration:

interface gpon-onu_1/2/14:50 name test description test tcont 1 profile 315MB-U gemport 1 tcont 1 gemport 1 traffic-limit downstream 630MB-D service-port 1 vport 1 user-vlan 20 vlan 20

It is important to mention that I tested with a ZTE ONU that does obtain the IP from the first moment."
