Addition of ONT Huawei EchoLife HG8110 on Huawei SmartAX MA5683T

On the test, I wrote the profiles and added ONT Huawei EchoLife HG8110 to Huawei SmartAX MA5683T.

The first step is to connect to the Huawei SmartAX MA5683T and go into configuration mode:

enable
config

Create ont-srvprofile:

ont-srvprofile gpon profile-id 14 profile-name "Huawei HG8110"
ont-port pots 1 eth 1
port vlan eth 1 translation 228 user-vlan 228
commit

Create ont-lineprofile:

ont-lineprofile gpon profile-id 14 profile-name "Huawei HG8110"
tcont 4 dba-profile-id 11
gem add 1 eth tcont 4
gem mapping 1 0 vlan 228
commit

We learn the serial number of ONT and the number of the card to which it is connected by typing the command to search for new ONTs:

display ont autofind all

Let’s go into the setup mode of the desired Gpon card (in the port of which the ONT is connected):

interface gpon 0/5

Now add ONT with the serial number:

ont add 3 17 sn-auth "414C434CF23D5EAF" omci ont-lineprofile-id 14 ont-srvprofile-id 14 desc OPISANIE
ont port native-vlan 3 17 eth 1 vlan 228 priority 0

Where number 3 indicates the Gpon port number to which the ONT is connected.

The number 17 means ID ONT and is listed next in order after added in the ONT configuration, the list of occupied IDs can be seen after exiting the Gpon card setup mode and typing the command displaying the entire configuration (for each gpon port, their IDs ONT):

display current-configuration
display current-configuration | include service-port

Let’s exit the Gpon interface configuration mode:

quit

Add a service port that will give the Internet to ONT (the number 425 denotes the port service number and is taken from the free in the configuration):

service-port 425 vlan 228 gpon 0/5/3 ont 17 gemport 1 multi-service user-vlan 228

Save the configuration:

save

The standard IP address of Huawei EchoLife HG8110 is 192.168.100.1, the login is telecomadmin, the password is admintelecom.
In ONT, you do not need to configure anything.

How to find out the password for Huawei EchoLife HG8245

Configured today GPON ONT Huawei EchoLife HG8245C to OLT and it was necessary to go to its web interface to change the password on Wi-Fi, and the standard root login and password admin did not fit. I had to perform several manipulations.
Of course, to begin with, connect to any of the LAN ports, wait until the DHCP ONT is turned on, it will give out IP, such as 192.168.1.2 or set it manually.
Connect via telnet to ONT IP 192.168.1.1, enter login root and password admin.
Then type the following commands one at a time:

shell
cd /mnt/jffs2/
grep admin  myconfig.xml

As a result, the last command gives information about what is happening in the web interface:

useradmin
vufum

and

telecomadmin
nE7jA%5m

Passwords can also be written on the device label. In the settings you can change the password, in this case the user will be useradmin and the specified password.
For HG8245, the standard administrative login and password telecomadmin \ admintelecom, for users – admin/admin. For Chinese HG8245C standard – telecomadmin \ nE7jA%5m.
There may be further passwords for telecomadmin:

NWTF5x%RaK8mVbD
NWTF5x%

Adding ONT PICOTEL PU-G510 on Huawei SmartAX MA5683T

Suppose that we set up Huawei SmartAX MA5683T and added lineprofile/srvprofile using this instruction: Configuring Huawei SmartAX MA5683T through the console

Next, add ONT similarly as I wrote in the article Alcatel-Lucent I-010G

On the test after adding ONT PICOTEL PU-G510 to OLT Huawei SmartAX MA5683T, when connecting the computer to ONT – the Internet worked, when connecting the router – no.
Therefore, I still had to open the ONT web interface, pointing in the address line http://192.168.1.1 (login and password – admin), before registering the computer with a static IP 192.168.1.2.
In the web interface, select the menu “Admin” – “GPON Settings”, where “OMCI OLT Mode:”, if using Huawei OLT – select “Huawei OLT Mode” and click “Apply Changes”.

See how I did it on video:

Etnernet ports are disabled on ONT Huawei EchoLife

I recently noticed a problem that, when ONT, the Huawei EchoLife HG8110, HG8120 and HG8120R watched the Ethernet ports shutdown about 30 seconds after the ONT was turned on.
At the same time, ONT continued to work, the optical connection did not disappear.
On the Huawei EchoLife HG8110 the link did not disappear, but the interface ONT 192.168.100.1 stopped pinging.

The cause was defective power supplies.

Adding ONT Huawei EchoLife HG8120 and HG8120R

On the test I will use ONT Huawei EchoLife HG8120 (works only in Bridge mode as a media converter) and Huawei EchoLife HG8120R (can work as Router & Bridge, with reset settings has no configuration, so it works the same as HG8120 in Bridge mode).
The standard IP for both models is 192.168.100.1, the login is telecomadmin, the password is admintelecom.
I will use VLAN 228 for the Internet.

Dying gasp Alarm on Huawei OLT

Sometimes on Huawei OLT you can see Dying gasp Alarm (0x2e11a00b).

Since they often occur, most likely they can be seen by running the commands:

display alarm active alarmid 0x2e11a00b
display alarm history alarmid 0x2e11a00b

I will give an example:

ALARM 531377 FAULT MINOR 0x2e11a00b SERVICE QUALITY 2017-12-06 08:19:27+02:00
ALARM NAME : The dying-gasp of GPON ONTi (DGi) is generated
SRVEFF : SA
PARAMETERS : FrameID: 0, SlotID: 5, PortID: 6, ONT ID: 32, Equipment ID:
TL-GP110
DESCRIPTION : The ONT is power off
CAUSE : The power supply of the ONT is abnormal
ADVICE : Check the power supply of the ONT and ensure that the power
supply works in the normal state

These alarms occur when power is lost or the power cord is removed from the ONT, at this moment ONT manages to send the Dying gasp message to the OLT.
Dying gasp is also used on many other devices, for example, to correctly terminate the connection.

OID and MIB for Huawei OLT and ONU

Decoded from the firmware Huawei SmartAX MA5683T several OID.

Alarm solution 0x2e112007 “The OLT cannot receive expected optical signals from the ONT in four consecutive frames”

Recently noticed that OLT (MA5683T) disables one ONT and reports an alarm “0x2e112007”.

After watching the alarm history:

display alarm history all
display alarm active all
alarm active clear all
display alarm active all

Observed the following:

ALARM 470141 FAULT WARNING 0x2e112007 SERVICE QUALITY 2017-10-19 09:17:50+02:00
ALARM NAME : The distribute fiber is broken or OLT can not receive
expected optical signals from GPON ONT(LOSi)
SRVEFF : SA
PARAMETERS : FrameID: 0, SlotID: 4, PortID: 3, ONT ID: 38, Equipment ID:
I-010G
DESCRIPTION : The OLT cannot receive expected optical signals from the ONT
in four consecutive frames
CAUSE : (1) The fiber is broken
(2) The quality of the optical path is poor
(3) The ONT hardware fails
ADVICE : (1) Check tributary optical fiber connection and backbone
optical fiber orderly, clean the fiber connector and replace
the fiber if necessary
(2) Ensure that the optical attenuation of the optical path is normal
(3) Reset the ONT or replace the ONT
— END

I tried to activate ONT:

interface gpon 0/4
ont activate 3 38
quit

But OLT still turned it off, at different intervals of 1-10 minutes.

Example of viewing the statistics of the number of alarms:

display alarm statistics

Viewing the alarm configuration:

display alarm configuration 0x2e112007

The ONT model was TP-Link GP110 with a signal of -15 for receiving and 2.1-2.7 for sending.
We tried to replace ONT with Alcatel-Lucent I-010G, the signal became -17, and OLT even more often began to turn it off.
Cleaning the connectors and digesting the dividers also did not help.

The problem was in a sagging piece of cable that hung from a very high altitude, after its replacement, the alarm disappeared, and the send signal became stable 2.46.

Limiting access to management of Huawei SmartAX MA5600

For example, to allow to connect to the Huawei SmartAX MA5600 series via telnet only to the specified IP address ranges 192.168.0.100-192.168.0.254 and 172.16.24.1-172.16.24.50 we will connect to the device and go into the configuration mode:

enable
config

And execute the following commands (for non-specified IP access is immediately prohibited):

sysman ip-access telnet 192.168.0.100 192.168.0.254
sysman ip-access telnet 172.16.24.1 172.16.24.50
sysman firewall telnet enable

Similarly for SSH:

sysman ip-access ssh 192.168.0.100 192.168.0.254
sysman firewall ssh enable

And SNMP for example for one IP:

sysman ip-access snmp 192.168.0.100 192.168.0.100
sysman firewall snmp enable

To deny access to the specified subnet, we specify ip-refuse instead of ip-access, for example:

sysman ip-refuse telnet 192.168.1.200 192.168.1.220
sysman firewall telnet enable

On the test, I performed the settings for Huawei SmartAX MA5683T, they are essentially the same for the entire MA5600 series.

Reason for messages “Failure: System is busy, please retry after a while” on Huawei OLT

Once when executing commands in the Huawei SmartAX console, the MA5683T began to notice often the message:

Failure: System is busy, please retry after a while

As it turned out, the reason in my case was Zabbix, which every hour received SNMP levels ONT and drew graphics. SNMP requests from him were packed with packets of 30-50, separately for each port. I solved the problem by increasing the timeout in the Zabbix server configuration and the verification period for more hours, because OLT was slowly issuing information, Zabbix was not available, considered it inaccessible, paused briefly and sent requests again.
Also, in the settings of the Zabbix node, you need to uncheck “Use bulk requests”.
