Traffic Forwarding Fails in an ERPS Ring

Procedure

1. Check the port roles in the ERPS ring and status of each device in the ring.

   In an ERPS ring, there should be only one RPL owner port. Other ports are common ports or RPL neighbor ports.

   Run the display erps [ ring ring-id ] verbose command in any view to check whether the value of Ring State is Idle. (Perform this operation on each device in the ERPS ring.)

   If the ERPS ring is incomplete or its status is abnormal, perform the following operations:

   1. Verify that all nodes in the ERPS ring are added to the ERPS ring.
   2. Check whether the ERPS ring configuration including the ERPS version number and major ring/sub-ring on devices in the ERPS ring are the same.
   3. Verify that port roles, control VLANs, and protected instances are correctly configured on all nodes in the ERPS ring.
   4. Verify that ports can allow packets of the specified VLANs to pass.
