ERRORDOWN

ERRORDOWN

ERRDOWN_1.3.6.1.4.1.2011.5.25.257.2.1 hwErrordown

Description

ERRDOWN/4/ErrordownOccur: OID [oid] Error-down occured. (Ifindex=[INTEGER], Ifname=[STRING], Cause=[STRING])

The alarm was generated when an errordown event occurred.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.257.2.1 Warning communicationsAlarm(2)

Parameters

Name Meaning
oid Indicates the MIB object ID of the alarm.
IfIndex Index of an interface.
Ifname Interface name.
Cause Cause of the errordown event.

Impact on the System

After the errordown event occurs, traffic cannot be forwarded on relevant interfaces and services are interrupted.

Possible Causes

The faults detected by service modules triggered errordown events. The possible causes are as follows:
  • EFM detected a link fault, which can be a fault that occurred on the remote end or a threshold-crossing event.

  • The MSTP edge port received BPDU packets.

  • After the number of secure MAC addresses learned by an interface reaches the maximum value, the interface receives packets from another MAC address.

  • MAC address flapping occurred.

  • The number of CRC error packets received by the interface during the alarm interval reached the alarm threshold.

  • The number of link flappings during the link flapping period reached the alarm threshold.

  • The current optical power of the interface fell below the lower alarm threshold.

  • Attack packets occurred on the interface.

Procedure

  1. Locate the fault based on the value of the Cause field in the alarm.

  2. Check whether the interface is specified as an edge port.

    • If the interface is not specified as an edge port, go to Step 3.

    • If the interface is specified as an edge port, go to Step 4.

  3. Perform the following steps.

    • Run:

      interface interface-type interface-num

      The interface view is displayed.

    • Run:

      undo stp edged-port and undo shutdown

      The edge port configuration is removed. Check whether the log still exists. If the log still exists, go to Step 5.

  4. Collect log messages and contact technical support personnel.

ERRDOWN_1.3.6.1.4.1.2011.5.25.257.2.2 hwErrordownRecovery

Description

ERRDOWN/4/ErrordownRecover: OID [oid] Error-down recovered. (Ifindex=[INTEGER], Ifname=[STRING], Cause=[STRING], RecoverType=[STRING])

The error-down fault recovered.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.257.2.2 Warning communicationsAlarm(2)

Parameters

Name Meaning
oid Indicates the MIB object ID of the alarm.
Ifindex Index of an interface.
Ifname Interface name.
Cause Cause of an alarm.
RecoverType Recovery type: automatic recovery or recovery using a command line.

Impact on the System

Services will not be affected.

Possible Causes

  • Services that generated the errordown events were unbound from the errordown module.

  • Services associated with the errordown events recovered.

Procedure

  • This log message is informational only, and no action is required.

Related Information

None.
