Why the Fiber link fails to created between two Huawei DWDM device?

When you encounter fiber link fails to created between two NEs Huawei OTN network devices, you can analyze them in two step.

First,check the usage of the port as per below steps on the NMS:

Open NE explorer.

Open Signal view diagram.

Locate Huawei OSN 6800 OSN 8800 board which is in question.

Right click the board & choose (Show relevant fibers).

Check if any fiber is configured on that port.

If it is configured,delete it.

If no fiber is found configured on the port , carry out the second step of processing:

In Fiber/Cable Synchronization (Inventory > Fiber/Cable/Microwave Link > WDM Fiber/Cable Synchronization), check whether the desired port is found or not.

If yes, try to re-synchronize it. 

If no, proceed into the steps below to fix the issue:

1.Use Navigator to login into particular NE with the Error issue.

2.Use the command line "cfg-get-fibermgr:0,0,0,0" to list out all the logical fiber connection in that NE.

3.A list of logical fiber connection will be display.

For example: 0x00FDEFD         6        11     0x0WFDGRDF   8        4

                      Source Address   slot    port     Sink Address   slot   port

4.Use command "cfg-del-fibermgr: " to delete desire port.Make sure to get the correct information before proceeding to delete the logical fiber.

5.If the error shows it’s the source, then check the source address, and if it’s sink then check the sink address.

6.Once the logical fiber is deleted, the NE on the NMS will show the red arrow logo on the NE icon which indicate changes are successfully made and require to synchronize.

7.Proceed to "Synchronize the NE Configuration"  to synchronize  the NE.

8.Once the NE is synchronized, the logical fiber connection should be able to be created as it needed to be.

Root Cause

the root cause is due to incomplete deletion of the logical fiber connection/trail

Solution

Clear the port by delete the associated fiber using navigator

Which is the innovation of Huawei OSN 6800/8800 system?

Huawei OSN 6800 and OSN 8800 system innovations are the three-level traffic grooming infrastructure:                                                          

 1. integrating dynamic cross-connect (Multi-degree ROADM)

 2. flexible electronic grooming 

 3. embedded L2 switch processing capability

How to Back Up the NE Database to the SCC Board on Huawei DWDM Equipment?

You need to back up the NE database during daily maintenance, to ensure that Huawei TN52SCC board of the NE automatically restores to normal operation after a data loss or equipment power failure. When you back up the NE database to the SCC board, you actually back up the NE data in the DRDB database of the SCC board to the Flash database. When the NE is restarted after a power failure, the SCC board automatically reads the configuration from the FLASH and issues the configuration to the boards.

Prerequisite

You are an NMS user with "Administrators" privilege.

You must log in to the NE as an NE user with system level authority.

Tools, Equipment and Materials

U2000 or Web LCT

Precautions

By default, the NMS automatically backs up the NE database into the flash memory every 30 minutes.

Procedure on the U2000

1. Visit the following navigation path.
   
2. Back up the NE database to the SCC board on Huawei OSN 6800.
   

Procedure on the Web LCT

1. Select one or more NEs in the NE list. Click BackUp NE Database > BackUp to SCC.
   The NMS takes a few minutes to back up the NE database. Do not perform any operation in the process of backup.
2. Click OK in the confirmation dialog box.
3. Click Close in the Operation Result dialog box is displayed.

Which slots on Huawei DWDM equipment can be inserted into TN11M4002?

It depends on DWDM models, before buying Multiplexing Board TN11M4002 spare part, you need check your your device lots, because TN11 occupies 3 slots, which TN12 only occupies 2 slots.

Some questions and Answers about HG8546M that ISP encountered

Q: We bought Huawei ONT HG8546M, but when we add it to our network , the V1R9 U2000 is asking for a XML file related to HG8546M, what's the problem?

A: From your sreenshot,it is a "capability.XML" file, which is contained in the U2000 version file,your R9 U2000 have Huawei ONT R12, R13 capability.XML, but have no R16 or later capability.XML., so you need a new version U2000 with ONT R16 or later capability.XML.included.

Q: In our network, we only have R9 U2000 to manage Huawei OLT ONT, do you have one with newer version?

A: We have R14 U2000 at hand, but it hasn't been installed yet, because we have a Huawei OSN 6800 project which needs R9 U2000.

Q: May I have R14 U2000 for testing my HG8546M?

A: You can send email to supports@thunder-link.com, and they will response you very soon.
