In this article I will give an example of GPON OLT BDCOM GP3600-08B configuration.Continue reading “Configuring BDCOM GP3600”
Suppose we went into the ONT TP-LINK TX-6610 web interface (standard IP 192.168.0.1, admin login, admin password) and specified transparent mode in the settings.
Watch how this is done in my video:
On the test, I will configure the time on the Huawei SmartAX MA5683T.Continue reading “Setting the time on the Huawei SmartAX MA5600”
I will give below an example of some commands and their description for managing users who manage the device.Continue reading “Create and manage users on the Huawei SmartAX MA5683T”
Suppose Huawei MA5683T has already added a lot of ONTs and they work, dba-profile created, but we need to add an ONT with a VLAN that has not yet been added and profiles have not been created with it.Continue reading “How to add ONT with new VLAN on Huawei MA5683T”
To view information about the ONU / ONT, connect to Huawei SmartAX MA5683T via telnet using the putty utility or via the windows command line, for example, by typing the command:Continue reading “View information about ONU on Huawei SmartAX MA5600”
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:
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:
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.
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.
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:
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.
