GPON OLT to ONU Provisioning: Profile Configuration

Bringing a GPON subscriber online is a strictly ordered procedure: the OLT cannot register an ONU until the DBA, line and service profiles exist, and no traffic flows until a service-port binds the ONU to a VLAN. Skip a step and you get the most common field symptoms — the ONU shows as autofind forever, or it comes online but the customer has no internet. This runbook follows a real Huawei MA5600T/MA5800 deployment order and lists the verification command after each stage.

1. Confirm Boards Before Anything Else

Newly inserted GPON boards appear as autofind and must be confirmed before they become active. Do this on first install and after any card replacement.

MA5683T(config)#display board 0
MA5683T(config)#board confirm 0
! or per slot
MA5683T(config)#board confirm 0/1
MA5683T(config)#save

Target state: every service board reports Normal or Active_normal. If a board stays in autofind 30 seconds after confirmation, re-run display board 0 and check the backplane seating.

2. VLANs, Uplink and Management IP

MA5683T(config)#vlan 10 smart
MA5683T(config)#vlan desc 10 description "Management"
MA5683T(config)#vlan 101 smart

! uplink: SCUN card slot 8, port 0
MA5683T(config)#port vlan 10 0/8 0
MA5683T(config)#port vlan 101 0/8 0

! management VLAN and default route
MA5683T(config)#interface vlanif 10
MA5683T(config-if-vlanif10)#ip address 192.168.1.100 255.255.255.0
MA5683T(config-if-vlanif10)#quit
MA5683T(config)#ip route-static 0.0.0.0 0.0.0.0 192.168.1.1
MA5683T(config)#display vlan all
MA5683T(config)#save

On MA5800 the uplink port is configured through the GIU interface (interface giu 0/8, then network-role 0 uplink) before VLANs are added to it.

3. DBA, Line and Service Profiles (in That Order)

! upstream bandwidth profile: 1 Gbit/s maximum, type 4
MA5683T(config)#dba-profile add profile-id 10 profile-name maxbw-1G type4 max 1024000
MA5683T(config)#dba-profile add profile-id 20 profile-name plan-100M type4 max 102400

! line profile: T-CONT -> GEM port -> VLAN
MA5683T(config)#ont-lineprofile gpon profile-id 10 profile-name line-vlan101
MA5683T(config-gpon-lineprofile-10)#tcont 1 dba-profile-id 10
MA5683T(config-gpon-lineprofile-10)#gem add 0 eth tcont 1
MA5683T(config-gpon-lineprofile-10)#gem mapping 0 0 vlan 101
MA5683T(config-gpon-lineprofile-10)#commit
MA5683T(config-gpon-lineprofile-10)#quit

! service profile: ONU UNI ports and VLAN translation
MA5683T(config)#ont-srvprofile gpon profile-id 10 profile-name srv-vlan101
MA5683T(config-gpon-srvprofile-10)#ont-port eth 1
MA5683T(config-gpon-srvprofile-10)#port vlan eth 1 translation 101 user-vlan 101
MA5683T(config-gpon-srvprofile-10)#commit
MA5683T(config-gpon-srvprofile-10)#quit
MA5683T(config)#display ont-lineprofile gpon all
MA5683T(config)#display ont-srvprofile gpon all

The DBA profile sets upstream bandwidth, the line profile maps GEM ports to VLANs, and the service profile describes the customer-side ports. All three must exist and be referenced before an ONT can pass traffic.

4. Enable Auto-Find and Register the ONU

MA5683T(config)#interface gpon 0/1
MA5683T(config-if-gpon-0/1)#port 0 ont-auto-find enable
MA5683T(config-if-gpon-0/1)#display ont autofind 0
! note the serial number, e.g. 48575443522C499D

MA5683T(config-if-gpon-0/1)#ont add 0 0 sn-auth 48575443522C499D omci   ont-lineprofile-id 10 ont-srvprofile-id 10 desc Customer-01
MA5683T(config-if-gpon-0/1)#ont port native-vlan 0 0 eth 1 vlan 101 priority 0
MA5683T(config-if-gpon-0/1)#quit

MA5683T(config)#service-port 100 vlan 101 gpon 0/1/0 ont 0 gemport 0   multi-service user-vlan 101 tag-transform translate
MA5683T(config)#display ont info 0/1 0 0
MA5683T(config)#save

The service-port line is not optional — an ONU that shows Run state: online but has no service-port entry will still drop all subscriber traffic. After the service-port is created, confirm the ONU state and the traffic counters:

MA5683T(config)#display ont info 0/1 0 0
MA5683T(config)#display service-port all
MA5683T(config)#display ont optical-info 0/1 0
MA5683T(config)#display ont wan-info 0/1 0 0

Troubleshooting the Usual Four Failures

• ONU never appears in autofind: optical budget or splitter problem — check Rx/Tx power in display ont optical-info, and confirm auto-find is enabled on that exact port.
• ONU online, no traffic: missing service-port, mismatched user-VLAN, or the uplink port does not carry the service VLAN.
• Registration fails with a profile error: the referenced line/service profile ID does not exist or has unsaved changes (run commit inside the profile, then save).
• Slow speeds for one subscriber: DBA profile max rate too low or shared T-CONT contention — verify the plan value against display dba-profile all.
