2. The physical link became faulty, causing the error frame or error code.

Procedure

  1. Check the value of the EventLogType field in the trap:

    • 1: indicates a trap about error codes. Then, go to Step 2.

    • 2: indicates a trap about error frames. Then, go to Step 3.

    • 4: indicates a trap about error frame seconds. Then, go to Step 4.

  2. Run the display this command in the interface view to check whether the efm error-code threshold 0 command is configured.

    • If so, go to Step 6.

    • If not, go to Step 5.

  3. Run the display this command in the interface view to check whether the efm error-frame threshold 0 command is configured.

    • If so, go to Step 7.

    • If not, go to Step 5.

  4. Run the display this command in the interface view to check whether the efm error-frame-second threshold 0 command is configured.

    • If so, go to Step 8.

    • If not, go to Step 5.

  5. Check whether the physical link is faulty.

    • If so, go to Step 9.

    • If not, go to Step 10.

  6. Run the efm error-code threshold threshold command in the interface view to reconfigure the threshold for detecting error frames on the current interface as required. Then, check whether the alarm is cleared.

    • If so, go to Step 11.

    • If not, go to Step 5.

  7. Run the efm error-frame threshold threshold command in the interface view to reconfigure the threshold for detecting error frames on the current interface as required. Then, check whether the alarm is cleared.

    • If not, go to Step 5.

  8. Run the efm error-frame-second threshold threshold command in the interface view to reconfigure the threshold for detecting error frame seconds on the current interface as required. Then, check whether the alarm is cleared.

    • If so, go to Step 11.

    • If not, go to Step 5.

  9. Change the physical link and then check whether the alarm is cleared.

    • If so, go to Step 11.

    • If not, go to Step 10.

  10. Collect alarm information and configuration information, and then contact technical support personnel.

  7. Restore the module associated with EFM, and then check whether the alarm is cleared.

    • If so, go to Step 13.

    • If not, go to Step 12.

  8. Run the efm enable command in the interface view of the remote device to enable EFM. Then, check whether the alarm is cleared.

    • If so, go to Step 13.

    • If not, go to Step 12.

  9. Run the undo shutdown command in the interface view to check whether the alarm is cleared.

    • If so, go to Step 13.

    • If not, go to Step 6.

  10. After the remote device works properly, check whether the alarm is cleared.

    • If so, go to Step 13.

    • If not, go to Step 12.

  11. Replace the physical link and then check whether the alarm is cleared.

    • If so, go to Step 13.

    • If not, go to Step 12.

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

IfIndex

Interface index

IfName

Interface name

Impact on the System

EFM OAM loopback cannot be initiated.

Possible Causes

802.3ah loopback failed after no response to an 802.3ah loopback request was received within a specified period of time.

Procedure

  1. Check whether the remote interface denies the remote loopback request from the local end.

    Run the display current-configuration command. Check whether the efm loopback ignore-request command is used.

    • If this command is used, the remote interface denies the request. Run the undo efm loopback ignore-request command to enable the remote interface to receive the remote loopback request. Then go to Step 2.

    • If this command is not used, the remote interface is able to receive the request. Then go to Step 3.

  2. Then check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 6.

    • If the alarm is not cleared, go to Step 3.

  3. Check the EFM status.

    Run the display efm session all command. Check whether the value of the EFM State field is detect.

    • If the value of the EFM State field is detect, go to Step 5.

    • If the value of the EFM State field is not detect, go to Step 4.

  4. Check whether the physical link is working properly.

    • If the physical link is working properly, go to Step 5.
    • If the physical link is not working properly, troubleshoot the link fault (for details, see "Physical Interconnection Troubleshooting").

  5. Collect alarm information and configuration information, and then contact technical support personnel.
