Parameters

Name Meaning
OID Indicates the ID of the MIB object.
EntityPhysicalIndex Indicates the physical index.
BaseTrapSeverity Indicates the alarm severity.
BaseTrapProbableCause Indicates the possible causes of the alarm.
BaseTrapEventType Indicates the alarm type.
EntPhysicalContainedIn Indicates the parent index of the entity.
EntPhysicalName Indicates the name of the entity.
RelativeResource Indicates the part related to the alarm.
ReasonDescription Indicates the description of the alarm cause.

Impact on the System

The problematic board does not work, and services on the board are interrupted. If a PHY failure has occurred, the RUN indicator on the board is off, and the Alarm indicator is steady red.

Possible Causes

Cause 1:

Optical modules used on the board are non-Huawei-certified switch optical modules. This alarm may also be reported for early delivered Huawei optical modules because vendor information of these optical modules is not recorded.

Cause 2:

The link between the CPU and PCI bridge has failed. (PCI stands for Peripheral Component Interconnect.)

Cause 3:

The link between the CPU and forwarding module has failed.

Cause 4:

The erasable programmable logic device (EPLD) does not work normally.

Cause 5:

The field programmable gate array (FPGA) does not work normally.

Cause 6:

The network processor (NP) does not work normally.

Cause 7:

The phase-locked loop (PLL) is abnormal.

Cause 8:

The complex programmable logical device (CPLD) does not work normally.

Cause 9:

The link between the CPU and PCI-PCIe bridge has failed. (PCIe stands for Peripheral Component Interconnect Express.)

Cause 10:

Physical ports on the chip do not work normally.

Cause 11:

Fans do not work normally.

Cause 12:

The Centralized Monitoring Unit (CMU) of the switch does not work normally.

Cause 13:

An error occurs when operations are performed on the flash memory.

Cause 14:

The PHY layer does not work normally.

Cause 15:

The TCAM does not work normally.

Cause 16:

The RTC does not work normally.

Procedure

  1. If non-Huawei-certified switch optical modules are used (cause 1), use either of the following methods to clear the alarm:

    1. If the optical modules were early delivered from Huawei, the alarm does not need to be handled. Run the transceiver phony-alarm-disable command to disable the alarm for non-Huawei Switch-nertified optical modules. If you cannot confirm whether the optical modules were early delivered from Huawei, contact technical support personnel.
    2. If the optical modules are non-Huawei-certified switch optical modules, replace them with Huawei-certified switch optical modules. Use either of the following methods to determine whether an optical module is a Huawei-certified switch optical module:
      1. Run the display transceiver command to check information about the optical module. If the Vendor Name field does not display HUAWEI, it is not a Huawei-certified switch optical module.
      2. Run the undo transceiver phony-alarm-disable command to enable alarm for non-Huawei-certified switch optical modules. If an alarm is generated for the optical module, the optical module is not a Non-Huawei-certified switch optical module.
        NOTE:

        Huawei-certified switch optical module identification is supported since V200R001.

        Boards with manufacture date later than June 30, 2013(January 1, 2016 for QSFP+ 40GE optical modules, CFP 40GE optical modules and CFP 100GE optical modules) in their electronic labels are considered new boards. The boards can report alarms periodically after non-Huawei-certified switch optical modules are installed. Old boards do not report alarms for non-Huawei-certified switch optical modules.

  2. If cause 1 is excluded, reset the board and check whether the alarm is cleared.

    • If so, the alarm handling ends.
    • If not, go to step 3.

  3. Replace the board and check whether the alarm is cleared.

    • If so, the alarm handling ends.
    • If not, collect alarm information and configuration information, and then contact technical support personnel.
