Impact on the System

Part of services were interrupted.

Possible Causes

Cause: The number of the Eth-Trunk member links that were Up was smaller than the lower threshold value that was set, which caused the LAG to become Down. As a result, a PLL trap was generated.

Procedure

  1. Run the display interface brief command to check whether the interface is Down.

    • If so, go to Step 2.
    • If not, go to Step 4.

  2. Run the undo shutdown command to check whether the alarm is cleared.

    • If so, go to Step 10.
    • If not, go to Step 3.

  3. Check whether the physical link is faulty.

    • If so, go to Step 7.
    • If not, go to Step 4.

  4. Run the display eth-trunk [ trunk-id [ interface interface-type interface-number | verbose ] ] command to check whether there are member interfaces in the LAG.

    • If so, go to Step 5.
    • If not, go to Step 8.

  5. Run the display trunkmembership eth-trunk trunk-id command to check whether the lower threshold for Eth-Trunk member links is set in the LAG; whether the number of Eth-Trunk member links that are successfully negotiated is smaller than the lower threshold for the Eth-Trunk member links that can be Up.

    • If so, go to Step 6.
    • If not, go to Step 9.

  6. In the Eth-Trunk interface view, run the least active-linknumber link-number command to correctly set the lower threshold of Trunk member links that can be Up. Then, check whether the alarm is cleared.

    • If so, go to Step 10.
    • If not, go to Step 9.

  7. Repair the physical link and then check whether the alarm is cleared.

    • If so, go to Step 10.
    • If not, go to Step 4.

  8. Run the eth-trunk trunk-id command in the interface view and add the current Ethernet interface to the Eth-Trunk interface as required. Then, check whether the alarm is cleared.

    • If so, go to Step 10.
    • If not, go to Step 5.

  9. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
  10. End.
