Description
After the network converged, the local bridge was elected as the new root bridge in the topology.
Parameters
| Parameter Name | Parameter Meaning |
|---|---|
| ProcessID | Indicates the ID of an MSTP process. |
| InstanceID | Indicates the instance ID. |
Possible Causes
Cause 1: The local bridge was added into a new network topology.
Cause 2: The priority of the local bridge was increased.
Cause 3: The root bridge in the original topology was faulty.
Cause 4: The priority of the root bridge in the original topology was reduced.
Procedure
- Cause 1: The local bridge was added into a new network topology.
- Cause 2: The priority of the local bridge was increased.
- Cause 3: The root bridge in the original topology was faulty.
- Cause 4: The priority of the root bridge in the original topology was reduced.
- Run the stp [ instance instance-id ] priority priority command or the stp [ instance instance-id ] root primary command on the original root bridge to re-specify the original root bridge as the root bridge. Then, check whether the alarm is cleared. If the alarm persists, go to Step 2.
