Impact on the System

This trap is generated when the status of a common interface changes. This trap may affect the neighbor status. If the interface goes Down, the neighbor relationship will be interrupted.

Possible Causes

1. The physical interface went Up or Down.

2. The OSPFv3 neighbor relationship was being established.


  1. Run the display rm interface and display ipv6 interface brief commands to check whether the interface is Down.

    • If the physical interface is Down, check the link. Then check whether the trap is cleared.
      • If so, go to Step 4.

      • If not, go to Step 2.

    • If the physical interface is Up, go to Step 2.

  2. Run the display ospfv3 interface command to check whether the current interface is Up.

    • If so, go to Step 4.

    • If not, go to Step 3.

  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
