Learn how to display optical module information on Huawei devices using specific commands and understand the diagnostic details of optical modules.
Check whether the firewall supports the optical module based on the model of the optical module inserted into the interface and hardware description in the product documentation.
The optical module type does not match the optical fiber type. At least one of the two optical interfaces has been manually shut down. The transmit power of the optical module is too low or too high. The
Huawei is very open when it comes to 3rd party SFP. In most cases, all SFPs work, but it generates a message every day, which fills the log unnecessarily. This can be disabled. When
The possible cause of the LASER_MODULE_MISMATCH alarm is as follows: 1.The optical port type supported by the physical board does not match the type of the opticalmodule
Context If optical modules that are not certified for Huawei data center switches are used on devices, the devices will generate a large number of alarms to prompt users to replace these optical modules with
Possible Causes The optical module is not a Huawei-certified optical module. A software bug occurs, leading to a failure to read optical module information.
When using switches, we may encounter many confusions, such as what types of optical modules are needed for different models of Huawei switches, and how to resolve issues encountered
Remove and reinstall the optical module. If the fault persists, replace the optical module with a normal one of the same type to check whether the optical module is faulty. If the fault persists, collect log
This field indicates whether the rate of the optical module installed on the port matches the port rate. For example, if a non-XGE optical module is installed on an XGE port, the rate of the optical module
For details, see How Can I Determine Whether an Optical Module Is Huawei-Certified. If so, collect alarm information and configuration information, and then contact technical support
Check the model and working mode (single-mode or multimode) of the optical modules on the connected devices. Use the patch cords accordingly. If the optical port still fails to go Up, replace the
exception, SFP is not certified. (EntityPhysicalIndex=67453134, BaseTrapSeverity=5, BaseTrapProbableCause=136192, BaseTrapEventType=9, EntPhysicalContainedIn=67108873
Solve the problem of alarm indicator steady on by clear the alarm after it is confirmed that customer pull out the optical module and shutdown interface manually
For checking transmission links on Huawei Routers, it is good to know how to find out the optical power of 100GE modules or interfaces for troubleshooting and making sure the desired or
Unlock Huawei OLT devices to support any ONT brand ONU. Learn how to unlock Huawei OLT devices to support third-party ONT.
Check whether the optical module is Huawei-certified. If it is not certified by Huawei, replace it with a Huawei certified one. Remove and reinstall the optical module.
Possible Causes Cause 1: The optical module is not a Huawei-customized optical module. If this optical module was delivered from Huawei early. Cause 2: Temperature of the
Some non-Huawei-certified switch optical modules are not designed in compliance with EMC standards and have low anti-interference capability. Additionally, they bring electromagnetic
The following uses the Moduletek SFP-10G-LR module connected to a Huawei S6700 switch as an example to introduce how to read information of the connected optical module on a
Huawei switches using non-certified optical module may not be able to read the information, can not guarantee the accuracy of the information read, recommend the use of Huawei certified optical
Possible Cause The working rate, duplex mode, and negotiation mode of the two ends of the optical interface are different. The port does not match the optical module. The optical fiber does not match
In past projects and testing experience, it was commonly believed that Huawei CE series switches would not generate alarms when using third-party optical modules, while
