The owner node cannot receive SF packets from a faulty node when the link state is normal

The link between the owner node and the faulty node is available, but the owner node cannot receive SF packets sent by the faulty node. The RPL port is blocked.

Possible reasons include:

• ERPS is not enabled for some nodes on the ERPS ring.

• The ring IDs are different for the nodes on the same ERPS ring.

• The control VLAN IDs are different for the nodes in the same ERPS instance.

• A port on the ERPS ring is faulty.

To resolve the problem:

• Use the display erps command to examine whether ERPS is enabled for all nodes on the ERPS ring. If ERPS is disabled for some nodes, use the erps enable command to enable ERPS for the nodes.

• Set the same ring ID for all nodes on a ERPS ring and configure the same control VLAN for all nodes in an ERPS instance.

• Use the display erps detail command to examine the port status for all nodes. Bring up the ports in down state.

• Use the debugging erps command on all nodes to view debugging information about packets and node status.
