Initial configuration of OLT ZTE C300 and ONU ZTE F601 with Internet access

The purpose of this guide is not to forget how to customize this type of “olts”, which is called “from scratch”.
A very narrow task will be realized. Namely, the head will be connected at one end to a higher server simulating the provider. The second end will be connected to the end computer through the “numenera”.
The task is to see the ISP server from the end device and run test traffic.
In this guide the incoming channel to OLT is fed to SFP+ port (xgei_1/19/1) in vlan 2200
ONU is connected to the first port of the board, which is inserted in the ninth slot.

All the starting manipulations can be seen in a similar guide. We will go straight to setting up the “head” itself

Step zero
The standard password is:
User password: zxr10

Going into privileged mode.


Next, enter the configuration mode and enter the command that will increase the duration of our session, after which “unlogging” will occur up to 200 minutes. (by default this value is 5 minutes and this time is not enough for coffee or pee).

conf terminal

line console idle-timeout 200

See what cards we have, what version and how we found them

show card

At the moment we are interested in two boards GTGH into which the “ONU” will be plugged and XUVQ, SFP module is inserted into one of its slots.

Step one
Let’s try to connect our head to the provider’s server.
For example, the ISP gave us the following parameters:
ip adress:
vlan: 2200

Create vlan

vlan 2200

Exit vlan settings


Set up an external channel from our “olt” to the ISP server.

interface xgei_1/19/1
switchport mode trunk
switchport vlan 2200 tag
no shutdown
interface vlan2200
ip address
ip route

If you see exclamation marks after the ping command – congratulations – the easiest part of configuring our “olt” is complete.

Go to the interface of our board and activate one (first) port
(here and below, pay attention to which mode you are in. Otherwise you will get an error.
The pictures below show everything)

conf terminal
interface gpon-olt_1/9/1
no shutdown

If everything went smoothly – on “ONU” the LOS lamp will stop blinking red and the PON lamp will start blinking green
Let’s see what unregistered “ONUs” our head has seen on this port

show gpon onu uncfg

In our example we see one unregistered “ONU”
Add an unauthorized ONT to the system configuration

interface gpon-olt_1/9/1
onu 1 type ZTE-F601 sn ZTEGC6A23B45

After 20 to 30 seconds, we check that the “head” has seen it.

show gpon onu state

(The PON lamp on the “ONT” should stop flashing and will be on continuously)
Create profiles on OLT for users as per your tariff policy.

profile tcont UP-500MB type 4 maximum 520000
profile traffic DOWN-500MB sir 520000 pir 540000
profile tcont UP-1GB type 4 maximum 1024000
profile traffic DOWN-1GB sir 1024000 pir 1024000

Prescribing settings for a specific “ONT”

interface gpon-onu_1/9/1:1
sn-bind enable sn
tcont 1 name T-INET profile UP-1GB

gemport 1 name G-INET tcont 1
gemport 1 traffic-limit downstream DOWN-1GB
switchport mode trunk vport 1

pon-onu-mng gpon-onu_1/9/1:1
gemport 1 flow 1
vlan port eth_0/1 mode tag vlan 2200

interface gpon-onu_1/9/1:1
service-port 1 user-vlan 2200 vlan 2200

pon-onu-mng gpon-onu_1/9/1:1
vlan port eth_0/1 mode tag vlan 2200

Checking for macs

show mac

As you can see from the picture in the 2200 vlan on one side is the mac address of the remote server and on the other side is the mac address of the end device.
To check that the traffic between my end device which is connected to the tested device I use iperf3. The server part is installed on the provider’s side – the client part on my local machine.
Run – if we see a similar picture – it means that we have succeeded.
(network card settings and iperf startup commands are not given in this guide).

If you want to remove “ONT” from the list

interface gpon-olt_1/9/1
no onu 1
show gpon onu uncfg
