What Can I Do If Two Connected Optical Ports on Huawei Switch Cannot Turn Up?

What Can I Do If Two Connected Optical Ports on Huawei Switch Cannot Turn Up?

Do the following if two connected optical ports cannot be up:

1. Check the port configurations. Ensure that the two ports are not shut down and have the
same duplex mode, rate, and negotiation mode.

2. Check the optical modules and fibers on switch like S6720-54C-EI-48S-AC. Ensure that the two ports use the same type of
optical modules, and the port rate is the same as the rate of optical modules. The optical
modules must match the fibers. Single-mode fibers are inserted into single-mode optical
modules and the multi-mode fibers are inserted into multi-mode optical modules.

3. Check whether the receive or transit power of the optical ports is within the allowed
range. If the receive or transmit power is excessively high or low, ports cannot turn Up.
The excessively long transmission distance or low optical fiber quality may also be the
reason why ports cannot turn Up.

4. If the preceding items are all normal, perform internal loopback test on the ports.
Connect the head and tail of a fiber to an optical module to check whether the port can
go Up.

You can also run the loopback internal command in the interface view to configure the
loopback function on Ethernet ports. This function can test port hardware performance
without connecting optical fibers to the port. If the port is Up, the port hardware is in
good condition.

5. If the fault cannot be located after the preceding operations are performed, replace the
optical modules or fibers.

Huawei MA5800 X7/15/17 Main Processing Board MPLB

Huawei H901MPLB board is a control board on Huawei MA5800. It is the core of the system control and service switching and aggregation. The H901MPLB board can also function as the management and control core of the integrated network management system (NMS). It communicates with service boards about the key management and control information through the master/slave serial port and inband GE/10GE upstream channel. In this manner, the H901MPLB board configures, manages, and controls the device, and also implements the simple route protocol functions

Supports active/standby switchover

Supports load sharing mode, doubling processing performance

Supports ISSU, saving the upgarde interruption time

Supports synchronization Ethernet

Supports 1588v2 and 1588ACR

Supports interfaces CON (RJ-45), ETH (RJ-45), ESC (RJ-45).

Supports Communication Interfaces TX0 RX0 to TX3 RX3 (4 x SFP+/SFP 10GE/GE ports).

Configuring an Huawei ONT VAS Profile

Huawei ONT value-added service (VAS) is used to support the function of provisioning the ONT value-added service on the ONT like GE ONT HG8546M, and to set the parameters for the VASs on the ONT, such as the ONT value-added service. Therefore, upgrade the ONT before configuring the VAS for the ONT.

Configuring an ONT VAS Profile

After configuring an ONT VAS profile and binding it to an ONT successfully, you can activate the ONT and directly apply the value-added service defined by the profile to the subscribers of the ONT. Each ONT can be bound to only one value-added service configuration profile.

Context

Value-added service configuration profiles vary with the types of the ONTs and software versions. An ONT value-added service (VAS) profile applies only to a certain ONT type and software version. This section considers Huawei HG8240 profile as an example.

To create a general ONT VAS profile based on existing profiles, right-click, and choose Create General VAS Profile from the shortcut menu.

Procedure

1. Choose Configuration > Access Profile Management (traditional style) from the main menu or select Fix-Network NE Configuration in Application Centerand choose Access Service > Access Profile Management (application style) from the main menu.

2. In the dialog box that is displayed, choose PON Profile > ONT VAS Profile from the navigation tree.

3. Click the ONT VAS Profile tab.

4. In the information list, right-click and choose Add from the shortcut menu.

5. In the dialog box that is displayed, set Profile Name, Vendor ID, Terminal Type, and Version. 

Key Item	Description
Import	Imports the .xml file that contains service configuration data to the configured VAS profile.
Export	Exports the parameters in the configured VAS profile to an .xml file.

6. Click OK.

Result

On the Terminal Reference tab, you can query the ONTs bound to this VAS profile.

Follow-up Procedure

If you want to bind a general ONT VAS profile to an Huawei ONT/ONU, select the right record, right-click, and choose Bind General VAS Profile from the shortcut menu.

Why Does Subcard LS5D00X4SA00 Fail to Register on S5320-32C-HI-24S?

Subcard LS5D00X4SA00 Fail to Register on Huawei S5320-32C-HI-24S, that's why?

Below are possible causes:

1, S5320-32C-HI-24S does not support the subcard.

2, The subcard is not hot swappable and can register successfully only after the switch restarts.

3, The subcard is not in a good contact with the backplane.

4, The system version of the switch needs upgrading.

When this occurs, send the bar code of the switch subcard LS5D00X4SA00 and S5300 switch version information to technical support personnel so that the technical support personnel can fix the problem quickly.

What Are the Functions of the HiGig Interface on the ETHB Board?

The HiGig interface provides a communication channel for two adjacent ETHB boards to implement binding of two adjacent ETHB boards. Two adjacent ETHB boards can implement load sharing and redundant protection only after they are bound together.

Because MABA, MABC.VER A, MABH.VER B, and MABV.VER B backplanes do not provide the HiGig interface, the ETHB board provides such an interface on the front panel. The HiGig interfaces of two ETHB boards are connected by using an external mini SAS high-speed cable. In this way, the two ETHB boards can communicate with each other. To set two ETHB boards to be in a protect group or to implement load sharing between two ETHB boards, connect their HiGig interfaces.

The MABC.VER B and MABH.VER C backplanes provide the HiGig interface. Therefore, two adjacent ETHB boards on Huawei MA5603T can communicate with each other through the backplane directly and they can implement binding without external mini SAS high-speed cables.

How to Display IGMP Messages on Huawei MA5600T

When the multicast duplication point is on Huawei MA5600T, how to display the IGMP messages exchanged between the MA5600T and the upper-layer device and between the MA5600T and IGMP users?

EPBA board:

• To display the messages, do as follows:

  huawei#terminal debugging
  % Current terminal debugging is on
  huawei#terminal monitor
  % Current terminal monitor is on
  huawei(config)#debugging igmp all
  

• To cancel the function of displaying the messages, do as follows:

  huawei#undo terminal debugging
  huawei#undo terminal monitor
  huawei#undo debugging igmp

Boards other than the EPBA board:

• The messages can be displayed only based on the index of the IGMP service port. To display the messages, do as follows:

  huawei#terminal debugging
  % Current terminal debugging is on
  huawei#terminal monitor
  % Current terminal monitor is on
  huawei(config)#debugging igmp service-port 68
  

• To cancel the function of displaying the messages, do as follows:

  huawei#undo terminal debugging
  huawei#undo terminal monitor
  huawei#undo debugging igmp

• The preceding methods apply to V800R006C02 and V800R008.
• After the function of displaying IGMP messages is enabled, the device performance may be affected. Therefore, disable this function when it is not used.

What is the Differences Between VDSL2 Service Boards?

Based on the number of supported users, VDSL2 service boards supported by the MA5616 can be classified into 16-channel VDSL2 service board, 24-channel VDSL2 service board, 32-channel VDSL2 service board, 48-channel VDSL2 service board, and 64-channel VDSL2 service board. These boards support VDSL2 and VDSL2 over POTS/ISDN access services.

The following tables list differences between VDSL2 service boards supported by Huawei MA5616.

• ^[1]: When AC power supply is used, the H83BVDMM board must work with the H831PAIC power board.
• ^[2]: Users can switch a configuration mode. To do so, log in to Huawei MA5616 as a super user and run the switch vdsl mode to command in diagnose mode. The default configuration mode is TR129. Considering the development trend, TR165 is recommended because it is more flexible than others.
• Vectoring-supported service boards take effect only when they work with power boards supporting vectoring
