VSI-Name indicates the VSI name.
OCTET Indicates MAC address flapping information.

Impact on the System

Traffic cannot be received correctly.

Possible Causes

Cause 1:

The interfaces that formed a loop were added to the same VSI.

Cause 2:

Cables were connected incorrectly.

Cause 3:

No loop prevention protocol such as STP was enabled.

Procedure

  1. Connect cables on the interfaces correctly and check whether the alarm persists.

    • If so, go to step 2.
    • If not, no further action is required.

  2. Check whether the two interfaces that learn the same MAC address can be added to different VSIs according to the networking.

    • If so, go to step 3.
    • If not, go to step 4.

  3. Add the two interfaces that learn the same MAC address to different VSIs. Then check whether the alarm persists.

    • If so, go to step 4.
    • If not, no further action is required.

  4. Enable a loop prevention protocol such as STP. Check whether the alarm persists.

    • If so, contact technical support personnel.
