qosUnmatchedPolicyDscpTrusted 1.3.6.1.4.1.9.18.2.1.4.1.1.5

If this attribute is true, then the Dscp associated with the packet is trusted, i.e., it is assumed to have already been set. In this case, the Dscp is not rewritten with qosUnmatchedPolicyDscp (qosUnmatchedPolicyDscp is ignored) unless this is a non-IP packet and arrives untagged. The packet is still policed as part of its micro flow and its aggregate flow. When a trusted action is applied to an input interface, the Dscp (for an IP packet) or CoS (for a non-IP packet) associated with the packet is the one contained in the packet. When a trusted action is applied to an output interface, the Dscp associated with the packet is the one that is the result of the input classification and policing.
