LPT_CFG_CLOSEPORT

LPT_CFG_CLOSEPORT

Description

The LPT_CFG_CLOSEPORT alarm indicates that the LPT function shuts down a service port. After detecting that the remote access port fails or the aggregation port at the local NE fails, the LPT function automatically shuts down the local access-point port and reports this alarm.

Attribute

Major

Equipment alarm

Parameters

None.

Impact on the System

When this alarm is reported, a port is shut down. If no protection is configured on the port, services carried on the port are interrupted. If protection is configured on the port, services are switched to the standby link for transmission.

Possible Causes

Possible causes of the LPT_CFG_CLOSEPORT alarm are as follows:

  • A port failure is detected on the remote access point.
  • The aggregation port at the local end is faulty.
  • The LPT service network is faulty.

Procedure

  1. On the U2000, check whether the remote aggregation port reports the ETH_LOS or LSR_NO_FITED alarm.
    If... Then...

    The ETH_LOS or LSR_NO_FITED alarm is reported

    Handle the ETH_LOS or LSR_NO_FITED alarm, and check whether the LPT_CFG_CLOSEPORT alarm is cleared. If the LPT_CFG_CLOSEPORT alarm persists, go to the next step.

    The ETH_LOS or LSR_NO_FITED alarm is not reported

    Go to the next step.

  2. On the U2000, check whether the local aggregation port reports the ETH_LOS or LSR_NO_FITED alarm.
    If... Then...

    The ETH_LOS or LSR_NO_FITED alarm is reported

    Handle the ETH_LOS or LSR_NO_FITED alarm, and check whether the LPT_CFG_CLOSEPORT alarm is cleared. If the LPT_CFG_CLOSEPORT alarm persists, go to the next step.

    The ETH_LOS or LSR_NO_FITED alarm is not reported

    Go to the next step.

  3. Check whether a fiber cut or a tunnel signal degrade occurs on the LPT service network.
  4. Rectify the fault that occurs on the service network. Then, check whether the LPT_CFG_CLOSEPORT alarm is cleared.
    If... Then...

    The alarm is cleared

    No further action is required.

    The alarm persists

    Contact Huawei technical support engineers to handle the alarm.
