Symptom: QOS policies might not download upon reload if same COS value is matched between class-fcoe and any other class. Following error message might be observed upon reload: %IPQOSMGR-4-QOSMGR_PPF_WARNING: PPF library warning: Ses ff0101d930000002 Database download error 0x41ee005f type 1 from client id 0x40000290 uid 656 vdc 0 slot 1 node 1 for nodes . Conditions: Under certain mis-configuration the parser does not reject configuration and QOS policies are also applied real time. By default class-fcoe matches to COS 3 and similar match of COS value is not rejected. Example: class-map type qos class-fcoe class-map type qos match-any signalling-global match cos 3 match dscp 24,26 #show policy-map system Service-policy (qos) input: classify-5548-global policy statistics status: disabled Class-map (qos): class-fcoe (match-any) Match: cos 3 >>>>> by default set qos-group 1 Class-map (qos): signalling-global (match-any) Match: cos 3 >>> explicitly configured Match: dscp 24,26 set qos-group 3 Ideally parser should reject configuration and give such a warning: ERROR: Unable to perform the action due to incompatiblity: Module 1returned status "same 'match cos' value can not be shared by class-fcoe and another class"
