Description of VLAN Types in Huawei OLT

In Huawei OLT, there are several types of VLAN, briefly describe them:

1) Standard VLAN
Ethernet ports in the Standard VLAN see each other, Ethernet ports of different VLANs are isolated from each other.

2) Smart VLAN
Smart VLAN can have many service ports that are isolated from one another in one VLAN, service ports in different VLANs are also isolated from each other. This type I usually use when setting up Huawei OLT.

One MUX VLAN can only contain one service port. service ports in different MUX VLANs are isolated from each other.

4) Super VLAN
Super VLAN is based on the 3 level, contains the subvlans (mux or smart), which can interact via arp-proxy.

The solution to the error “Service virtual port has existed already”

I noticed once on Huawei MA5683T when I added the service port for ONT the following error:

Failure: Service virtual port has existed already

As reported by the error, the service port is already registered for this ONT.
In my case, there was simply a misprint in ONT ID, it was accidentally indicated by the wrong one, after specifying the correct service port, it was registered.

And if you need to register several service port for one ONT, then see my article – Adding an ONT with trunk port to Huawei SmartAX MA5683T

Adding an ONT with trunk port to Huawei SmartAX MA5683T

Here is an example of adding ONT so that at the output of the ethernet port all VLANs are tagged.
Suppose OLT is configured for my article – Configuring Huawei SmartAX MA5683T through the console.
ONT for the test I’ll take TP-Link GP110 with the configured mode transparent and off DHCP, well, in fact with other single-port ethernet ONT setting is similar.

Install GPON card in Huawei OLT

On the test I’ll take the H805GPFD board with 16 GPON ports and install it in OLT Huawei SmartAX MA5683T without shutting it down.
After inserting on the board, the RUN / ALM indicator flashed red and literally a minute later green.

Optionally, before inserting the board, you can turn on alarm output and then turn off:

alarm output all
undo alarm output all

When the board is already installed, in the configuration mode, confirm it:

board confirm 0/3

And enable ONT detection on ports:

interface gpon 0/3
port 0 ont-auto-find enable
port 1 ont-auto-find enable
port 2 ont-auto-find enable
port 3 ont-auto-find enable
port 4 ont-auto-find enable
port 5 ont-auto-find enable
port 6 ont-auto-find enable
port 7 ont-auto-find enable
port 8 ont-auto-find enable
port 9 ont-auto-find enable
port 10 ont-auto-find enable
port 11 ont-auto-find enable
port 12 ont-auto-find enable
port 13 ont-auto-find enable
port 14 ont-auto-find enable
port 15 ont-auto-find enable

Let’s look at the information about the board:

display board 0/3
display cpu 0/3

Exit the configuration mode and save the current configuration:


If you are using the U2000, then by clicking on the OLT, select “Synchronize NE Configuration Data”.
In the old version of U2000 R009 noticed that in the main window a question mark is displayed instead of the port of the board, in this case it is necessary to update U2000 or for example add ONT through GPON – GPON Management – GPON UNI Port tab – select port – ONU Info tab – Auto Discover ONUs.
