Description (partial)


Traffic that should be 'denied' is in fact matched and permitted. As per the MQC specification, 'actions' (permit or deny) defined within an ACL which is used for packet classification, are ignored when used within a QOS policy. All lines within the ACL are considered to be 'permit' lines even if the action has been defined as 'deny'.

A QOS policy which has a class-map using an ACL for packet matching, which in turn has ACL entries with 'deny' set as the 'action'.
