Impact on the System

Part of services were interrupted.

Possible Causes

The number of the Eth-trunk member links that can be selected is smaller than the lower threshold value.

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

10. End.
