Troubleshooting RRPP
Symptom
When the link state is normal, the master node cannot receive Hello packets, and the master node
unblocks the secondary port.
Analysis
The reasons can be the following:
•
RRPP is not enabled on some nodes in the RRPP ring.
•
The domain ID or primary control VLAN ID is not the same for the nodes in the RRPP ring.
•
Some ports are abnormal.
Solution
•
Use the display rrpp brief command to check whether RRPP is enabled for all nodes. If not, use the
rrpp enable command and the ring enable command to enable RRPP and RRPP rings for all nodes.
•
Use the display rrpp brief command to check whether the domain ID and primary control VLAN ID
are the same for all nodes. If not, set the same domain ID and primary control VLAN ID for the
nodes.
•
Use the display rrpp verbose command to check the link state of each port in each ring.
