Adding ONT to an Huawei SmartAX MA5683T

Huawei SmartAX MA5683T OLT Configuration Guide

Comprehensive 2026 guide for configuring Huawei GPON OLT and registering ONT devices (EchoLife HG series). Follow this sequence to ensure proper service provisioning.

Values in red are examples — replace them with your own profile IDs, VLANs, serial numbers, and port numbers.

Quick Navigation

1. Access Configuration Mode
2. Create Service Profile
3. Create Line Profile
4. Register ONT Device
5. Provision Service Port

Step 1 – Access Configuration Mode

Establish a connection to the OLT and enter global configuration mode.

enable
config

Step 2 – Create ONT Service Profile

Defines port capabilities (Ethernet/POTS) for the ONT hardware.

ont-srvprofile gpon profile-id 999 profile-name "Service_Profile"
ont-port eth 1 pots 1
commit
quit

Step 3 – Create ONT Line Profile

Assigns T-CONT (bandwidth) and GEM ports for traffic mapping.

ont-lineprofile gpon profile-id 999 profile-name "Line_Profile"
tcont 1 dba-profile-id 10
gem add 1 tcont 1
gem mapping 1 0 vlan 999
commit
quit

Step 4 – Register ONT

Search for unconfigured devices and register using the SN (Serial Number).

interface gpon 0/5
display ont autofind all
ont add 1 1 sn-auth 48575443XXXXXXXX omci ont-lineprofile-id 999 ont-srvprofile-id 999 desc "Client_ONT"

Step 5 – Create Service Port

Enable data flow by mapping the OLT VLAN to the ONT GEM port.

service-port 10 vlan 999 gpon 0/5/1 ont 1 gemport 1 multi-service user-vlan 999 tag-transform translate

Verification Commands

FAQ

How do I find the ONT serial number?
Run display ont autofind all inside the specific GPON interface.

What is the typical Rx Optical Power range?
Ideally between -8dBm to -27dBm. Anything higher than -28dBm may cause frequent disconnections.

Do the profile IDs need to match on every step?
Yes — the profile-id used in Step 2 and Step 3 must match the ont-lineprofile-id and ont-srvprofile-id referenced in Step 4, or the ONT registration will fail.

What does the VLAN number need to match?
The VLAN used in the line profile’s gem mapping should match the VLAN in the Step 5 service-port command, so traffic is tagged consistently end to end.
