9.2.2 Priority Mapping Results Are Incorrect
This section describes the troubleshooting flowchart and provides a step-by-step troubleshooting
procedure to use when priority mapping results are incorrect.
Common Causes
This fault is commonly caused by one of the following:
l Packets do not carry the priority trusted by the inbound interface.
l The parameter override is not configured in the trust command on the inbound interface.
l Priority mapping in the priority mapping table is incorrect.
l There are configurations affecting priority mapping on the inbound interface, including:
– qos car inbound with remark-8021p or remark-dscp configured
– traffic-policy inbound with remark 8021p, remark dscp, or remark local-
precedence configured, or car with remark-8021p or remark-dscp configured
l There are configurations affecting priority mapping on the outbound interface, including:
– qos car outbound with remark-8021p or remark-dscp configured
– traffic-policy outbound with remark 8021p, remark dscp or remark local-
precedence configured, or car with remark-8021p or remark-dscp configured
