8) Verification
After the configuration, you can use the
display
command to view RRPP configuration and operational
information on each device.
Troubleshooting
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 may be:
z
RRPP is not enabled on some nodes in the RRPP ring.
z
The domain ID or primary control VLAN ID is not the same for the nodes in the same RRPP ring.
z
Some ports are abnormal.
Solution:
z
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.
z
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.
z
Use the
display rrpp verbose
command to check the link state of each port in each ring.
z
Use the
debugging rrpp
command on each node to check whether a port receives or transmits
Hello packets. If not, Hello packets are lost.
