– If the traffic behavior contains the re-marking action, delete the re-marking action
from the traffic behavior or delete the traffic policy from the interface.
– If the traffic policy fails to be applied or the traffic behavior does not contain the re-
marking action, go to step c.
l If the traffic-policy inbound command is not used, go to step c.
Step 4 Check whether there are configurations affecting priority mapping on the outbound interface.
1. Check whether traffic policing defining the re-marking action is configured on the outbound
interface.
Interface-based traffic policing takes precedence over priority mapping. If interface-based
traffic policing defining the re-marking action is configured on the outbound interface, the
AR2200-S re-marks packet priorities.
Run the display this command in the view of the inbound interface to check whether the
qos car outbound command with remark-8021p or remark-dscp configured has been
used.
l If yes, delete the re-marking action or run the undo qos car outbound command to
delete traffic policing.
l If not, go to step b.
2. Check whether the traffic policy defining the re-marking action is configured in the
outbound direction on the outbound interface.
A traffic policy takes precedence over priority mapping. If the traffic policy used on the
outbound interface contains priority re-marking, remark local-precedence, or car with
remark-8021p or remark-dscp, the AR2200-S re-marks priorities of packets matching
the traffic classifier.
Run the display this command in the view of the outbound interface to check whether the
traffic-policy outbound command has been used.
l If the display traffic-policy applied-record command has been used, run the display
traffic-policy applied-record command to check the traffic policy record and the traffic
behavior in the traffic policy.
If the traffic policy has been applied successfully, run the display traffic behavior
user-defined command to check whether the traffic behavior contains packet priority
re-marking, internal priority re-marking, or car with remark-8021p or remark-dscp.
– If the traffic behavior contains the re-marking action, delete the re-marking action
from the traffic behavior or delete the traffic policy from the interface.
– If the traffic policy fails to be applied or the traffic behavior does not contain the re-
marking action, go to step 5.
l If the traffic-policy outbound command is not used, go to step 5.
Step 5 Collect the following information and contact Huawei technical support personnel.
l Results of the preceding troubleshooting procedure
l Configuration file, log file, and alarm file of the AR2200-S
